PREFACE  TO  THE  SECOND  SERIES. 


The  study  of  Skin  Diseases  without  cases  or  colored  plates  is  like  the  study  of  oste. 
ology  without  bones,  or  the  study  of  geography  without  maps.  However  comprehensive 
or  practical  a  text-book  may  be,  its  verbal  descriptions  cannot  compare  in  value  with  a 
sight  of  the  thing  described,  or,  what  is  next  best,  its  faithful  representation 

It  is  now  eight  years  since  the  publication  of  the  first  edition  of  "  Photographic  Illus- 
trations of  Skin  Diseases."  The  extensive  sale  of  the  work  in  this  country  and  its 
translation  and  sale  abroad  have  been  largely  owing  to  the  fact  that  it  is  the  first  atlas 
in  which  the  recent  and  improved  photographic  processes  have  been  employed  in  the 
portrayal  of  diseases  of  the  skin.  A  continued  demand  for  these  plates  is  considered  by 
the  author  as  not  only  an  evidence  of  their  value  and  adaptation  to  the  wants  of  the 
general  practitioner  but  also  an  ample  excuse  for  a  new  and  improved  series. 

In  the  present  work  many  of  the  illustrations  have  been  doubled  or  trebled  in  order 
to  show  different  jihases  of  a  given  disease.  In  the  text,  which  has  been  increased  to 
over  two  hundred  quarto  pages,  special  attention  has  been  devoted  to  the  diagnosis  and 
treatment  of  skin  diseases,  and  the  work  is  now  presented  as  a  combined  atlas  and  text, 
book. 

As  heretofore,  the  plates  are  made  from  photographic  negatives  taken  from  life. 
The  Artotype  reproductions  of  these  negatives  are  the  work  of  Mr.  Edward  Bierstadt, 
and  the  hand-coloring  of  the  plates  has  been  entrusted  to  the  well-known  medical  artist. 
Dr.  Joseph  Gtertner.

LIST     OF     ILLUSTRATIOl^S, 

WITH  NOTES  OF  CASES. 


I.  Seborrhcea. — J.  S.,  set.  18.  Patient 
of  Dr.  F.  T.  Brown.  The  eruption  of  six 
mouths'  staudiug  began  upon  the  nose  in  the 
fi/rm  of  fine  red  blotches,  upon  the  surface  of 
■which  a  soft  yellowish  crust  developed.  This 
showed  a  disposition  to  return  quickly  when- 
ever it  was  removed,  until  application  of  tar 
effected  a  cure 9 

II.  a.  Varicella.— Patient  of  Dr.  G. 
W.  Eobiuson,  at  the  New  York  Dispensary 

5.  Variola. — From  a  photograph  fur- 
nished by  Dr.  W.  0.  Cutler,  of  Chelsea,  Mass.     21 

III.  a.  Erythema  esfoliativum. — For 
full  report  of  case  see  page  31. 

J.  Erythema  BTTLLOSUM. — H.  B.,  set.  15. 
Photograph  taken  on  the  tenth  day  of  the 
eruption  which  ran  its  course  in  three  weeks. 
Subsequent  eruptions  occurred  in  this  pa- 
tient at  intervals  of  one  or  two  years    .         .     31 

IV.  Erythema  multiforme. — Patient 
sent  by  Dr.  Few<mith,  of  Newark,  to  the  Skin 
Clinic  of  the  College  of  Physicians  and  Sur- 
geons. The  case  presented  a  most  striking 
appearance  and  illustrated  an  unusual  com- 
bination of  the  niarginate,  annular,  vesicular 
and  bullous  lesions  of  multiform  erythema. 
The  disposition  of  vesicles  to  form  concentric 
circles  is  well  shown  upon  the  arm  and  near 
the  timbilicus  and  constitutes  what  has  been 
designated  "  Herpes  iris."  Upon  the  ijreast 
the  coalescence  of  the  ring  of  vesicles  has 
formed  an  annular  bulla,  a  lesion  which  is 
very  rarely  observed      .         .         .         .         .35 

v.  Urticaria. — Patient  of  Dr.  Sherwell. 
A  yotmg  woman,  thin,  ansemio  and  nervous, 
who  had  suffered  for  years  from  an  almost 
constant  tirticaria.  Her  skin,  at  first  glance, 
appeared  normal,  but  examination  quickly 
revealed  the  fact  that  the  slightest  external 
irritation  would  produce  a  marked  conges- 
tion, while  a  scratch  or  trifling  blow  would 
quickly  evoke  one  or  more  distinct  wheals. 
In  the  photographic  gallery  the  operator 
focussed  upon  the  smooth  skin  of  the  arm  and 
while  preparing  his  p'ate  I  traced  with  a 
w.)oden  tooth  pick,  the  letters  which  are 
seen  in  the  illustration.  By  the  time  the 
photographic  plate  was  in  tiie  camera  and 
ready  for  exposure,  these  letters  stood  out  in 
bold  relief,  in  the  form  of  white  linear  wheals 
apon  a  bright  red  background      .         .         .39 


VI.  Urticaria  piomentosa. — J.  W., 
set.  5^.  Eruption  appeared  first  at  18  months 
of  age  as  '"hives,"  but  the  lesions  became 
dark  and  persistent.  Very  slight  improve- 
ment under  treatment  .....     41 

VII.  a.  Derm.vtitis  calorica. — J.  N. 
A  young  man  had  his  fingers  frost-bitten,  and 
soon  after  applied  to  an  apothecary  who  gave 
him  tincture  of  Arnica  to  apply.  Within  fif- 
teen minutes  the  fingers  began  to  swell  and 
large  bullae  formed.  Ulceration  occurred  in 
this  case  after  the  dead  epidermis  was  re- 
moved. 

h.  Dermatitis  venenata. — This  photo- 
graph  was  taken  of  the  fore-arm  of  a  man 
who  had  worked  in  the  woods  and  evidently 
come  in  contact  with  poison  ivy.  The  skin 
was  greatly  swollen  and  covered  with  fine 
aggregated  vesicles 43 

Vill.  Eczema  erythematoscm. — M.  L., 
set.  66.  The  eruption  in  this  case  was  of  two 
years'  standing,  having  nearly  disappeared  in 
the  summer,  but  occurring  in  a  most  annoy- 
ing and  obstinate  form  during  the  winter 
months.  It  had  always  been  dry  upon  the 
face  although  there  coexisted  a  moist  eczema 
of  the  leg.  The  itching  of  the  face  was  ter- 
rible and  local  applications  failed  to  subdue 
it  except  when  combined  with  free  purgation 
which  tended  to  lessen  the  congestion  of  the 
skin  and  thus  afforded  relief        .         .         .     4» 

IX.  Eczrma  rcbrum  et  squamosum. — 
The  legs  of  this  patientwere  in  asimilarcon- 
dition  until  a  few  minutes  before  the  photo- 
graph was  takeu.  The  scales  from  one  leg 
were  then  removed  by  vigorous  friction  with 
green  soap,  and  a  smooth,  red,  angry-looking 
skin  expo-!ed;  numerous  ragged  rents  in  the 
tense  epidermis  are  plainly  seen     .         .         .     53 

X.  EczEM.s  SQUAMOSUM. — a.  J.  Z. ,  set.  20. 
Eruption  began  asanacuteeczema.  Amisture 
of  lime  waterand  linseed  oil,  equal  parts,  was 
freely  applied,  and  the  arm  placed  in  a  sling. 

b.  This  case  illustrates  a  rare  papilloma- 
tous condition  of  the  .skin  which  is  usuallv 
observed  u|)0u  the  lower  third  of  an  eczenia- 
tous  leg  (Eczema  verrucosum).  Above,  the 
ordinary  squamous  form  of  the  disease  is  seen    67 

XI.  Eczema  intertrigo. — Mrs.  B.,  set. 
4G.  Suffered  for  three  months  from  inter- 
trigo of  axillary,  sub-mammary  and  inguinal

regions.  An  eczematous  condition  of  the 
patches  gradually  developed  and  assumed  a 
distinctly  marginate  character      .         .         .61 

XII.  Eczema  faciei. — In  the  first  illus- 
tration, a  baby  seven  months  of  age,  the  in- 
flamed and  excoriated  skin  is  shown.  Tho 
second  illustration,  of  an  older  child,  presents 
a  similar  eruption  covered  by  a  thick  crust. 
(Eczema  impetiginosum.)     .         .         .         .65 

XIII.  (7.  Eczema  barbje. — In  this  case 
there  was  a  profuse  watery  discharge  which 
dried  and  formed  thick,  blood-stained  crusts. 
The  eruption  showed  a  predilection  for  hairy 
parts,  altliough  occurring  also  behind  the 
ears. 

b.  Sycosis  BARB.a. — In  this  case  the  in- 
flammatory process  was  deeper  seated,  involv- 
ing the  hiiir  follicles  and  producing  an  erup- 
tion of  n  inierous  aggregated  pustules. 

c.  Trichophytosis  bakb^. — The  para- 
sitic source  of  the  sycotic  inflammation 
in  this  cae  is  shown  by  the  number  of  cir- 
cnmscribeil  ]iatchcs  and  by  the  well-marked 
ring  upon  the  neck 67 

XIV.  a.  Eczema  squamosum,  b.  Syph- 
ILODEKMA  squamosum. — There  is  scarcely 
a  cutaneous  lesion  of  syphilis  so  difficult  to 
be  distinguished  from,  and  so  likely  to  be 
confounded  with  eczema,  as  the  squamous 
eruption  upon  the  palms  and  soles.  The 
tendency  of  eczema  to  fade  away  at  the  mar- 
gin of  the  patch  and  of  syphiloderma  to 
spread  with  an  abrupt  margin  and  to  heal  in 
the  centre,  is  shown  by  contrast  in  this  illus- 
tration   69 

XV.  Dermatitis  exfoliativa.  —  A 
young  woman  at  the  Skin  and  Cancer  Hos- 
pital who  .suffered  from  an  acute  attack  with 
complete  recovery  in  three  months       .        .     73 

XVI.  Psoriasis  guttata. — W.  S.,  sat. 
25.  Eruption  has  persisted  for  eight  years, 
nearly  disappearing  during  summer  months    76 

XVII.  Psoriasis  nummulata.  —  This 
form  of  the  eruption  often  succeeds  the  gut- 
tate  form.  Many  of  the  discs  show  a  tendency 

to  hf  al  in  the  centre 77 

XVI II.  Psoriasis  ANNULATA.— This  case 
shows  both  scaly  rings  and  the  gyrate  bands 
of  scales  which  are  frequently  seen  at  the 
margin  of  a  large  pigmented  area  from  which 

the  active  eruption  has  disappeared       .         .     79 

XIX.  PsOBiASiSDiFFUSA.— Patient  of  Dr. 
L.  D.  Bulklev.  In  this  ca.se  the  scales  had 
been  removed  leaving  smooth,  red,  infiltrated 
patches  with  an  elevated  border.  Upon  the 
forehead  the  eruption  is  seen  in  a  character- 
isiie  jfication  ......     81 

XX.  Psoriasis  makuum  et  pedum. — 
This  patient  had  suffereil  for  many  years  fiom 
recurrent  attacks  of  general  psoriasis.     The 


(6) 


rarity  with  which  this  disease  aSects  the 
palms  and  soles,  even  in  cases  where  the 
eruption  is  very  extensive  upon  other  parts, 
has  led  some  (myself  among  the  number) 
to  deny  its  existence  in  these  localities.  That 
it  may  occur  upon  the  palmar  and  plantar 
surfaces  in  an  exceptional  case  is  shown  by 
this  plate      

XXI.  a.  Pityriasis  circinata. — In  this 
case,  as  in  the  illustration,  the  strong  resem- 
blance of  the  eruption  to  ordinary  ringworm 
was  very  marked.  The  sudden  development 
of  hypersemic  patches,  the  irregularity  of  the 
border  and  absence  of  vesiculation.  the  tawny 
color  of  the  epidermis  and  slight  tendency  to 
a  steady  increase  in  size  were  considered  to 
be  distinguishing  features. 

b.  LiCHEX  PLANUS. — The  eruption  in  this 
patient  had  existed  for  three  months  and  was 
confined  chiefly  to  the  forearms.  The  patches 
were  diffused  and  very  irregular  in  outline 
and  there  were  but  few  of  the  characteristic 
isolated  papules    ...... 

XXII.  Lichen  ruber. — In  this  case  the 
eruption  began  on  the  extremities  in  the  form 
of  acuminate  red  papules  mostly  surmounted 
by  fine  scales.  These  lesions  increased  rapidly 
in  number  until  the  entire  surface  of  tho 
skin  was  involved  ..... 

XXIII.  Herpes  facialis. — Patient  of 
Dr.  G.  T.  Jackson.  Eruption  was  preceded 
by  vomiting,  chill  and  fever.  It  lasted  about 
ten  days 

XXIV.  a.  Zoster  frontalis. — Patient 
photographed  on  the  eighth  day  of  the 
attack.  There  had  been  tenderness  of  the  eye 
and  one-half  of  forehead  and  scalp  for  three 
days  before  the  appearance  of  the  first. patch 
over  eye-brow.  The  eruption  extended  back 
upon  the  crown  of  the  head  and  was  accom- 
panied by  swelling  of  the  cervical  glands. 
The  use  of  galvanism  relieved  her  suffering 
considerably  and  the  eruption  ran  its  course 
in  less  than  three  weeks. 

b.  Zoster  LUMBOCRURALis. — In  this  case 
the  eruption  was  quite  extensive  upon  the 
lower  portion  of  the  abdomen  and  upon  the 
thigh.  Phosphide  of  Zinc  was  given  without 
any  positive  result 

XXV.  Pemphigus. — A  patient  at  Bolle- 
vue  Hospital,  under  treatment  for  cerebral 
syphilis.  A  very  large  tense  bulla  upon  tho 
back  of  the  hand  had  just  broken  before 
photograph  was  taken,  exposing  a  raw  sur- 
face       

XXVI.  Acne.— The  first  illustration 
shows  a  well-marked  pustular  acne  with  some 
induration  of  the  lesions.  It  occurred  in  a 
strumous  subject  with  a  poor  circulation  and 
worse  digestion.

LIST    OF    ILLUSTRATIONS. 


The  second  illustration  shows  the  erup- 
tions as  it  so  frequently  occurs  upon  the  back  101 

XXVII.  PoRRiGO. — The  child  whose 
hands  are  shown  in  this  illustration  presented 
an  eruption  upon  the  face  as  well,  consisting 
of  flattened  vesico-j^ustules  with  a  depressed 
centre  and  some  tense  hemispherical  purulent 
bulla3.  These  lesions  upon  drying,  became 
covered  by  yellowish  or  dark-colored  crusts, 
which  when  scratched  off  exposed  a  red,  raw 
surface.  The  young  man  whose  fore-arms 
are  shown  presented  another  phase  of  the 
same  disease.  In  his  case  the  lesions  dried 
into  thick  yellowish  crusts,  and  wherever  the 
skin  was  excoriated  by  the  finger-nails,  new 
lesions  developed,  showing  plainly  the  con- 
tagious nature  of  the  purulent  secretion.  This 
patient  was  under  the  care  of  Dr.  G.  T. 
Elliot  at  the  Skin  and  Cancer  Hospital         .   105 

XXVIII.  Purpura. — These  illustrations 
show  the  eruption  in  the  form  of  small 
petechise  and  larger  ecchymoses.  In  the 
second  case  there  was  considerable  oedema 
and  tenderness  of  the  legs    ....  115 

XXIX.  a.  OoRNUA  CUTANEA. — This 
patient  had  a  cutaneous  horn  u])on  the  cheek 
about  an  inch  in  length  and  of  a  dirty  yel- 
lowi.«h  hue.  It  has  existed  for  several  years 
and  had  fallen  off  repeatedly  only  to  develop 
again.  Near  the  eye  was  a  lesion  resembling 
a  small  sujierficial  epithelioma  which  also 
showed  a  tendency  to  form  a  horny  excres- 
cence. Tlie  growths  were  removed  by  the 
curette  and  did  not  return. 

b.  Keratosis  FOLLicuLARis.  A  patient 
of  Dr.  P.  A.  Morrow  exhibiting  a  very  un- 
usual development  of  small  spinous  projec- 
tions from  the  follicles  on  various  portions  of 
the  body.  (See  Journal  of  Cutan.  and  Ven. 
Diseases,  Vol.  IV.) 127 

XXX.  Ichthyosis. — These  cases  of 
ichthyosis  simplex  were  congenital,  compara- 
tively well  in  summer,  and  did  not  affect  the 
general  health  of  the  patients.  In  the  first 
illustration  the  roughened  epidermis  is  well

County  Hospital.  Age  19.  Lower  extremi- 
ties enlarged  since  childhood,  following  post- 
scarlatinal oedema.  Ulceration  and  slough- 
ing took  place  in  this  case,  the  health  failed 
and  death  from  exhaustion  followed.

contrast  with  the  normal  skin,  especially  in 
summer 141 

XXXIV.  Alopecia  areata. — a.  A 
married  woman  in  delicate  health.  Patch 
of  six  weeks'  standing.  The  application  of 
compound  chrysarobin  pigment  was  soon  fol- 
lowed by  a  growth  of  fine  downy  hair. 

b.  A  young  man  working  on  a  farm  and 
not  at  all  nervous.  The  disease  affected  the

upon  the  cheek  of  the  first  patient  was  of 
thirty-four  years  duration.  The  ajiplication 
of  a  bichloride  of  mercury  ointment  (two 
grains  to  the  ounce)  was  continued  for  three 
months  with  the  effect  of  making  the  nodules 
smoother  and  paler. 

The  hand  of  the  second  patient  pre- 
sented an  eruption  similar  in  nature  to  lupus 
vulgaris,  though  differing  in  its  clinical 
aspect.  This  eruption  has  been  termed

DISEASES  OF  THE  SKIIT. 


CHAPTER    I. 

GLANDULAR    DISEASES. 

The  sebaceous  and  perspiratory  glands  of  the  skin  are  numerous,  and  called  upon  to  play 
an  important  part  in  maintaining  the  health,  not  only  of  the  skin,  but  of  the  whole  economy. 
A  disturbance  of  their  functional  activity  gives  rise  to  a  series  of  affections  which  are  gen- 
erally annoying,  and  often  of  serious  import  as  indications  of  constitutional  disease.  In 
various  affections  of  the  skin  the  glands  are  incidentally  involved,  and  often  become  the  seat 
of  inflammation  and  organic  change.  liut  in  the  present  Chapter  the  affections  resulting  from 
purely  functional  derangement  will  alone  be  considered. 

The  natural  secretion  of  the  glands  may  be  abnormally  increased  or  deficient  in  amount. 
It  may  be  changed  in  character  and  retained  within  the  gland  or  its  duct.  Inflammation  is  not 
an  essential  element  of  these  affections,  although  it  may  be  present  in  some  cases.  Acne,  a 
disease  of  the  sebaceous  glands  which  is  always  inflammatory  in  character,  wiU  be  considered 
among  the  other  inflammatory  affections. 

SEBORRHCEA. 

Synonyms — Ac?ie  sehacea. — Dandriff. 

Seborrhoea  is  an  affection  in  which  the  natural  secretion  of  sebaceous  matter  is  abnormally 
increased.  The  skin  may  appear  and  feel  oily  to  an  unnatural  degree,  constituting  the  form 
of  the  affection  which  is  known  as  seborrhoea  oleosa,  or  it  may  be  covered  by  greasy  scales  or 
friable  crusts,  to  which  condition  the  term  seborrhcea  sicca  is  applied.  The  affection  is  usu- 
ally confined  to  a  limited  portion  of  the  skin,  and  is  notably  frequent  upon  the  scalp,  face, 
breast  and  back.  The  oily  form  of  seborrhoea  in  a  mild  degree  occasionally  iiivolves  the 
whole  surface  of  the  body. 

Seborrltwa  capitis.  An  abnormal  increase  of  the  sebaceous  secretion  is  very  common 
upon  the  scalp.  In  infants  this  is  usually  a  poition  of  the  greasy  coating  \vhich  covers  the 
skin  of  the  foetus  {cernix  caseosa),  and  which,  owing  to  the  presence  of  the  hair,  is  not  re- 
moved from  the  scalp  at  the  first  washing  of  the  new-bom  infant  as  readily  as  it  is  from  the 
remaining  portion  of  the  body.    This  fatty  csoating  upon  the  scalp  is  apt  to  increase  when  strict

DISEASES  OF  THE  SKIN.— GLANDULAR. 

attention  to  cleanliness  is  not  observed,  and  assumes  in  time  a  dirty  yellowisli  or  bro^Y^i-ll 
Ime  from  the  admixture  of  dust  and  dirt.  It  is  usually  limited  to  the  crown  of  the  head. 
When  the  mother  or  nurse  is  imbued  with  the  absurd  notion  that  the  removal  of  this  "  ci-a- 
dlecap"  would  jeopardize  the  health  or  well-being  of  the  infant,  it  ma j' remain  a  year  oi 
two,  until  it  gradually  dries  and  becomes  loosened  and  cast  off  by  the  giowth  of  new  hair 
In  certain  cases  this  greasy  crust  becomes  heaped  up  in  dry,  undulating  masses,  and  iu  one 
case  I  have  seen  it  in  thick  masses  over  the  forehead  and  cheeks  as  well  as  upon  the  cro^ni  of 
the  head. 

Seborrhopa  ca]>itis  occurring  in  the  fonn  of  a  liquid  secretion  ia  adults  is  rarely  objection- 
able as  the  excessive  secretion  is  readily  absoi'bed  by  the  hair,  but  when,  as  is  far  more  fre- 
quently the  case,  it  occurs  in  the  form  of  a  dry  scurf,  it  is  apt  to  produce  more  or  less  irrita- 
tion of  the  scalp  and  to  seriously  interfere  with  the  natural  growth  of  the  hair.  This  phase 
of  seborrhoea  is  extremely  common  and  is  well  known  under  the  familiar  name  of  "dand- 
riff."  Numerous  fine  and  dry  scales  form  upon  the  scalp,  especially  upon  the  anterior  por- 
tion, and  occasion  considerable  annoyance  by  falling  upon  the  shoulders  in  a  more  or  less- 
copious  shower,  whenever  the  head  is  scratched  or  brushed.  A  slight  amount  of  j^ruritus  is 
commonly  present.  In  certain  cases,  chiefly  in  male  adults,  this  diy  seborrhoea  forms  a  thick 
crust  which  welds  the  hair  together  upon  the  surface  of  the  scalp  and  splits  into  fibres  some- 
what resembling  asbestos  when  the  hairs  are  forcibly  drawn  apart. 

Seborrhoea  faciei.  In  yoimg  persons,  particularly  those  subject  to  acne,  an  oily  condition 
of  the  forehead  and  nose  is  not  uncommon.  In  rare  instances  the  affection  exists  in  such  a 
ma  rived  degree  that  the  oil  wUl  collect  in  drops  upon  the  surface  of  the  skin.  In  the  diy 
foim  seborrhoea  is  most  apt  to  occur  in  the  vicinity  of  the  eyebrows  and  upon  the  bearded 
iwrtion  of  the  face,  and  usually  in  connection  with  seborrhoea  capitis.  Upon  non-hairy  por- 
tions of  the  face  it  is  most  likely  to  be  located  in  the  furrows  at  the  base  of  the  alcB  nasi, 
whence  it  may  extend  upon  the  sides  of  the  nose  and  upon  the  cheeks.  It  now  forms  a  dirty 
crust  beneath  and  around  which  the  skin  is  sometimes  considerably  inflamed. 

In  elderly  persons  with  a  wrinkled  and  discolored  skin  seborrhoea  often  appears  in  the 
foiTn  of  small,  dry  and  dark  crusts,  especially  upon  the  forehead,  temple  or  malar  region. 
Wh(m  this  crust  is  removed  a  red  and  sometimes  a  raw  patch  is  discovered.  These  patches 
often  iiroduce  a  faintly  marked  cicatricial  condition  of  the  skin,  and  may  become  the  seat  of 
lupus  or  epithelioma.  Upon  other  portions  of  the  body,  seborrhoea  is  frequently  met  with. 
Over  the  sternal  and  inter-scapular  region  it  is  common  in  the  oUy  form  and  occasionally  in 
the  fonn  of  pinkish  marginate  patches  covered  %vith  thin  greasy  crusts.  In  the  region  of  the 
clitoris  and  the  coronal  furrow  of  the  glans  penis  it  is  often  present,  and  when  frequent 
abhition  is  neglected,  it  often  results  in  a  disagreeable  accumulation  of  smegma  and  a  conse- 
quent balanitis  or  vulvitis. 

Di.\o.\osis.  The  oily  form  of  seborrhoea  is  not  readily  mistaken,  but  the  dry  fonn  of 
1  he  affection,  whether  occurring  upon  the  scalp,  face  or  body,  is  apt  to  be  confounded  with 
several  other  diseases.     In  seborrhoea  of  the  scalp  the  diagnosis  is  not  always  an  easy  matter. 

(10) 


SEBOREHCEA. 

-he  liue  oranny  scales  wMcli  constitute  "dandriff  "  are  usually  of  mingled  epideiinic  M.iics;' 
md  sebaceous  matter,  and  the  relative  proportion  of  these  constituents  is  subject  to  consider- 
able variation.  The  scales  may  be  very  largely  composed  of  dried  sebum,  in  which  case  the 
diagnosis  of  seborrhoca  must  be  made.  But  on  the  other  hand,  the  scales  are  often  dry, 
white  and  powdery,  and  contain  little  or  no  sebaceous  matter.  In  such  a  case  they  are  the 
result  of  a  pre-existing  hyper?eniia  of  the  scalp,  and  constitute  that  mildest  fonn  of  ery- 
thematous eczema  which  has  been  described  by  many  writers  as  a  distinct  disease  under  the 
name  of  Pityriasis.  It  is  often  difficult,  without  resorting  to  a  microscopical  examination  o) 
the  scales,  to  decide  whether  the  sebaceous  or  the  epidennic  element  preponderates,  and 
many  cases  indeed  are  on  the  border  land  between  seborrhoea  and  pityriasis. 

^\^hen  seborrhoea  has  formed  a  dry  scurf  or  crust  upon  the  scalp,  it  bears  a  strong 
resemblance  to  an  eczema  which  has  reached  its  final  or  scaling  stage.  In  seborrhoea,  how- 
ever, the  crust  can  be  readily  removed  by  gentle  scrai^ing,  and  the  scalp  beneath  is  of  a  dul! 
greyish  or  pinkish  hue,  while  in  eczema  the  crust  is  adherent  and  the  scalp  beneath  it  is 
more  or  less  inflamed,  and  apt  to  bleed  if  the  crust  be  forcibly  removed.  In  seborrhoea  the 
affection  is  dry  from  the  outset,  while  in  eczema  there  is  usually  a  history  of  previous  mois- 
1  ure  and  a  considerable  amount  of  pruritus. 

Psoriasis  of  the  scalp  is  even  more  similar  in  appearance  to  seborrhoea,  and  is  very  apt 
to  be  mistaken  for  it  when,  as  occasionally  happens,  the  scaly  patches  are  not  present  upon 
other  portions  of  the  body.  But  the  scales  of  psoriasis  are  drier,  whiter  and  less  friable  than 
those  of  seborrhoea,  and  while  the  patches  of  the  latter  are  irregular  in  outline,  those  of  the 
former  are  commonly  circular  and  especially  apt  to  occur  along  the  frontal  margin  of  the 
scalp,  and  in  the  little  tuft  of  hair  which  extends  do^vn  in  front  of  the  ear. 

Seborrhoea  faciei  may  be  confounded  with  eczema,  lupus  erythematosus  and  rosacea. 
Occurring  as  it  frequently  does  in  the  furrow  upon  either  side  of  the  alw  na.n,  the  slvin 
beneii  ih  the  crust  is  apt  to  become  inflamed,  but  there  is  never  any  tendency  to  moisture,  as 
in  eczema.  Extending  upon  the  side  of  the  nose  and  cheek,  the  favorite  site  of  erythematous 
lupus,  an  error  in  diagnosis  becomes  quite  possible,  especially  as  the  sebaceous  glands  are 
involved  in  both  affections.  But  the  patches  of  lupus  are  characterized  by  a  more  chronic 
grade  of  inflammation,  a  slighter  amount  of  scaling,  and  by  a  somewhat  marginate  outline, 
which  the  patches  of  seborrhoea  never  present.  Lupus  also  leads  to  the  fonnation  of  cicatri- 
ces. SeborrhcEa  of  the  nose,  occurring  in  an  oily  form,  is  often  associated  with  slight 
redness  of  the  skin  and  hypertrophy  of  the  glands,  which  produces  a  notable  increase  in  the 
size  of  the  organ.  In  such  a  case  the  resemblance  to  rosacea  is  marked,  and  indeed  the  two 
diseases  are  not  infrequently  combined.  When  seborrhea  nasi  exists  alone  there  is  Uj 
capillary  dilatation  nor  formation  of  papulo  pustules  ("blossoms")  as  is  common  in  rosacea. 
Moreover  the  congestion  is  active  and  the  temperature  of  the  skin  is  elevated,  giving  rise  to  a 
burning  sensation,  while  in  rosacea,  on  the  other  hand,  the  congestion  is  passive,  the  tip  o? 
the  nose  feels  cooler  than  natural,  however  red  it  may  be,  and  there  are  no  subjectiv 
sensations.

DISEASES  OF  THE  SKIN.— GLANDULAR. 

In  the  very  rare  cases  of  seborrhce  sicca,  involving  a  large  portion  of  tlie  body  {S.  univer- 
salis,) the  diagnosis  of  ichthyosis  might  be  made.  The  nature  of  the  two  affections  however 
is  -widely  different.  In  the  former  there  is  an  increased  secretion  of  sebum,  forming  crusts, 
which  are  readily  removed,  leaving  the  skin  smooth  and  in  an  almost  nonnal  condition.  In 
the  latter  there  is  a  lack  of  fatty  secretion.  The  scales  are  epidei-mic  in  character,  not  readily 
removed,  and  the  skin  beneath  is  dry  and  thickened. 

Treatment.  If  the  systemic  conditions  which  predispose  to  seborrhcea  were  better 
understood  much  might  be  accomplished  by  attention  to  diet  and  internal  medication.  In 
the  present  state  of  our  knowledge  we  are  forced  to  rely  mainly  upon  external  treatment. 
There  are  two  objects  to  be  kept  in  mind  in  the  treatment  of  every  case,  viz.,  to  soften,  if 
necessary,  and  to  remove  the  sebaceous  secretion ;  and  to  stimulate  the  glands  to  healthy 
action.  The  first  aim  can  be  readily  accomplished,  the  second  sometimes  proves  to  be  a  diffi- 
cult task.  In  seborrhcea  oleosa  the  frequent  use  of  soap  tends  to  keep  the  skin  dry,  but 
rarely  effects  a  pennanent  change  in  the  condition.  After  bathing  the  skin  with  soap  and  hot 
water,  and  carefully  drying  it,  the  application  of  precipitated  sulphur,  tannic  acid,  or  some 
other  astringent  powder  is  usually  beneficial.  If  there  be  a  tendency  for  thin  crusts  to  form 
over  the  affected  surface  the  foIlo\ving  ointment  lightly  applied,  by  means  of  the  finger,  is

In  obstinate  cases  of  seborrhcea  of  the  nose,  and  these  cases  are  generally  obstinate,  I 
have  obtained  the  best  results  by  having  the  patient  rub  the  nose  vigorously  before  going  to

In  dry  seborrhcea  of  the  scalp  the  crust  may  be  readily  removed  by  soaking  it  thoroughly 

at  night  \vith  olive  oil  and  shampooing  the  head  in  the  morning  with  the  officinal  tincture  of 

green  soap.     This  will  leave  the  scalp  clean  and  natural  in  appearance,  but  a  cessation  of  the 

treatment  at  this  point  will  be  speedily  followed  by  a  return  of  the  crust.     The  patient  must 

therefore  be  directed  to  shampoo  the  head  twice  every  week,  or  oftener  if  it  seems  necessary, 

and  to  apply  meanwhile  some  slightly  stimulating  omtment  every  night.     Hyde  recommends

COMEDO. 

If  this  plan  of  treatment  is  carried  out  for  a  few  weeks  the  tendency  to  the  return  of  rlie 
i-rust  will  usually  cease.  In  the  many  cases  where  seborrhoea  does  not  form  a  thick  ci'iist 
upon  the  scalp,  but  occurs  in  the  form  of  dandriff  with  falling  of  the  hair,  it  is  often  neces- 
s;ny  to  prolong  the  treatment  for  several  months. 

COMEDO 

Synonyms — Acne  punctata  niyra — Black  heaiU. 

Comedo  is  an  affection  of  the  sebaceous  glands,  occurring  nlone  or  associated  with  acne. 
It  consists  in  an  excessive  secretion  of  sebaceous  matter,  which  becoming  hardened,  produces 
a  distension  of  the  sebaceous  ducts.  The  skin  may  be  tolerably  smooth  and  dotted  with 
numerous  dirty  specks,  which  indicate  the  mouths  of  distended  ducts,  or,  as  is  usualh'  i)ie 
case,  small  conical  papules  are  seen  with  black  dots  at  their  summits.  The  dark  color  of 
these  >' black  heads"  is  owing  to  the  adherence  of  particles  of  dirt  to  the  exposed  end  of  the 
fatty  plug  which  occupies  the  follicle.  In  patients  who  work  in  dusty  rooms,  and  especially 
among  such  as  are  sparing  in  the  use  of  soap,  these  black  dots  increase  in  number  and  prom- 
inence, until  the  face  looks  as  though  it  had  been  expo.sed  to  an  explosion  of  gunpowder. 
Unna,  of  Hamburg,  claims  that  the  black  end  of  the  comedo  is  not  due  to  the  admixture  of 
dirt,  but  results  from  the  presence  of  a  pigment.  W  hen  pressure  is  applied  to  opposite  sides 
of  a  comedo,  an  inspissated  mass  composed  of  sebum  and  eiuthelial  ceUs  can  be  extrnded  in 
the  shape  of  a  curdy  or  cheesy  "worm." 

The  affection  is  commonly  observed  upon  the  face,  although  the  upper  portion  of  the 
back  is  almost  as  frequently  its  seat.  Not  infrequently  a  few  comedos  (or  comedones,  as  they 
are  called  by  writers  who  prefer  to  retain  the  Latin  term),  are  seen  upon  the  sternal  region 
and  upon  the  sides  of  the  neck.  The  sebaceous  glands  of  the  nose,  which  are  numerous  and 
normally  of  large  size,  are  not  apt  to  be  gi'eatly  distended,  although  in  nearly  every  ca.se  of 
this  alfection  white  plugs  or  threads  of  sebum,  an  eighth  of  an  inch  or  more  in  length,  can  be 
expressed  from  the  follicles,  both  upon  the  tip  and  ahe  nasi.  In  the  concha  of  the  ear  the 
black  ends  of  a  group  of  comedos  are  frequently  seen.  In  this  location  they  are  firmly  im- 
bedded and  pressed  out  with  difficulty.  Upon  the  forehead  and  temples  comedos  do  not  at- 
tain as  large  a  size  nor  are  they  as  numerous  as  they  are  upon  the  cheeks.  They  may  be  soft, 
whitish,  an/l  curdy,  curling  as  they  are  extraded  from  the  sebaceous  ducts,  or  in  cases  of  long 
standing  iliey  may  be  more  or  less  hardened,  of  a  yellowish  color  and  jjyriform  shape,  and 
when  pressure  is  exerted  upon  the  walls  of  the  follicle  by  means  of  a  silver  tube  or  comedo- 
presser  they  pop  out  with  an  audible  sound.  Frequently  the  comedo  is  found,  upon  exami- 
nation, to  be  composed  of  three  parts,  a  black  end  corresponding  to  the  mouth  of  the  follicle. 
a  yellowish  or  homy  mould  of  the  duct,  and  a  soft  Avhitish  extremity  representing  the  fresh 
secretion  of  the  gland.  Microscopical  examination  of  the  sebaceous  matter  composing  the 
comedo  will  sometimes  reveal  the  presence  of  an  animal  parasite  called  the  stealozoon  or  aca- 
rus  folliculorum.    Several  of  these  microscopic  insects  may  be  found  in  one  follicle.     They  are 

(13) 


DISEASES  OF  TEE  SKIN.— GLANDULAR. 

perfectly  harmless,  and  occur  in  healthy  follicles  as  well  as  in  those  which  are  dislorxled  by 
an  accimuilation  of  sebum. 

Diagnosis.  Comedo  is  not  lUcely  to  be  mistaken  for  any  other  affection  of  the  skiu,  but 
in  the  treatment  of  acne  a  peculiar  blackening  of  the  mouths  of  the  sebaceous  glands  is  s/)me 
times  accidentally  produced,  and  this  condition  may  simulate  the  disease  under  consideration. 
\Vhen  ointments  or  lotions  containing  lead  or  mercury  have  been  applied  to  the  face,  and  a 
change  in  the  treatment  is  deemed  advisable,  an  ointment  or  lotion  containing  sulphur  is 
sometimes  thoughtlessly  prescribed  by  the  physician,  or  foolishly  applied  by  the  patient  with- 
out authority.  Under  such  circumstances,  a  chemical  combination  of  the  sulphur  with  the  lead 
or  mercury  takes  place,  and  to  the  patient's  dismay,  the  face  suddenly  assumes  an  appearance 
as  undesimble  as  it  is  unexpected.  The  cheeks,  and  especially  the  nose,  becomes  peppered 
\y\x\\  innumerable  black  dots,  each  one  indicating  the  orilice  of  a  sebaceous  follicle,  at  which 
point  the  above  mentioned  chemical  combination  has  taken  place. 

Treat JiENT.  The  treatment  of  comedo  is  usually  restricted  to  local  measures,  although 
attention  to  the  state  of  the  general  health  is  necessary  in  most  cases  to  check  the  tendency 
to  the  disorder.  Our  first  aim  should  be  to  evacuate  the  distended  ducts.  This  is  frequently 
accomplished  by  the  patient,  by  means  of  the  thumb-nails.  The  use  of  a  watch-key  is  a  bet- 
ter plan  of  treatment,  but  since,  on  account  of  its  square  bore  and  rough  end,  it  is  liable 
to  wound  the  skin,  several  little  comedo-pressers  have  been  devised  as  a  substitute.  The 
simplest  instrument  is  a  silver  tube,  live  or  six  centinieti-es  in  length,  Avith  rounded  extrem- 
ities, and  a  calibre  of  knitting-needle  size.  By  placing  the  end  of  this  tube  over  the  summit 
•  >f  the  comedo,  and  exerting  a  quick,  firm  pressure,  the  sebaceous  pliig  can  be  expressed  with 
tile  least  amount  of  discomfort.  In  pressing  out  comedos  over  bony  prominences,  such  as^ 
lh<-  cheek  bone  or  margin  of  the  jaw,  or  upon  the  nose,  care  must  be  exercised  lest  the  tube 
slip  ami  tear  the  surface  of  the  skin.  A  small  elongated  curette  can  often  be  used  to  better 
advantage  than  a  silver  tube,  especially  when  the  comedos  are  large  or  of  variable  size.  The 
bealc  of  the  curette,  which  is  held  at  an  angle  of  forty-five  degrees,  should  be  pressed  firmly 
ui)c>n  the  sldn  at  the  side  of  the  follicular  orifice,  and  by  performing  a  sort  of  tour  de  maiire 
with  the  instrument  kept  at  the  same  angle  with  the  skin,  pressure  is  successively  exerted 
tipon  each  side  of  the  comedo  and  its  easy  extrusion  from  the  duct  is  thus  accomplished.  In 
this  as  in  other  simple  manoeuvTes,  practice  makes  perfect.  When  the  comedos  are  consid- 
erably elevated  above  the  level  of  the  skin,  the  black  head  may  be  scraped  out  of  the  duct  by 
a  rapid  sweep  of  the  side  of  the  instrument,  after  which  a  natural  evacuation  of  the  gland 
will  soon  follow.  After  the  follicles  have  been  evacuated,  the  face  may  be  bathed  with  very 
hoi  wati-r  to  lessen  the  congestion,  which,  in  a  greater  or  less  degree  results  from  the  use  of 
any  iiitrunient.  The  daily  use  of  soap  should  be  prescribed,  both  for  the  sake  of  its  stimulant 
.iftidii  oil  the  gland^i,  and  for  the  purpose  of  removing  a  portion  of  the  fatty  matter  from 
.|ii<-i>  wliich  are  not  sufficiently  distended  to  warrant  the  use  of  the  comedo-presser.  Soap

MILIUM. 

When  there  is  any  tendency  to  glandular  inflammation,  and  the  use  of  soap  is  found  to  ag- 
gravate this,  it  is  well  to  bathe  the  face  in  warm  water,  to  which  a  little  borax  or  bran  may 
be  added.  Ladies  sometimes  object  to  the  use  of  soap  in  bathing  the  face,  on  account  of  the 
tense  and  shiny  condition  of  the  skin  which  is  sometimes  left.  This  is  easily  remedied  by 
slight  friction  with  a  piece  of  flannel  or  chamois-skin,  and  if  necessary,  by  the  application 
of  a  little  rice  powder  or  lycoiwdium.  As  a  lotion  to  be  used  in  cases  of  comedo,  the  follow- 
ing is  mildly  astringent  and  conducive  to  the  normal  action  of  the  glands  :

MILIUM. 

Synonym — Acne  punctata  albida. 

Milium  is  a  distended  sebaceous  gland,  forming  a  minute  whitish  tumor  of  the  skin.  It 
is  usually  of  the  size  of  a  pin's  head  or  a  mQlet  seed,  from  whence  it  derives  its  name.  It 
presents  the  appearance  of  a  little  pearly  globule  just  beneath  the  epidermis,  and  has  a  fine 
shotty  feeling  when  the  finger  is  passed  lightly  over  the  skin.  A  number  are  commonly  pres- 
ent in  a  given  case,  and  are  most  frequently  found  upon  the  eye-lids  and  the  malar  portion  of 
the  cheek.  They  are  most  apt  to  occur  in  middle  life  and  in  women  ^^ith  a  dark  sallow  slcin. 
They  form  gradually  and  for  some  time  may  escape  notice.  They  cau.^e  no  subjective  sensa- 
tion whatever,  and  often  remain  for  years  without  undergoing  any  ch.\uge  in  size  or  appear- 
ance, and  it  is  only  in  certain  cases  where  their  number  renders  them  •conspicuous,  that  the 
physician  is  called  upon  to  remove  them.  When  carefully  examined  after  removal  from  the 
«kin,  nulia  are  found  to  be  small  globular  masses  of  a  dense  cheesy  or  calcareous  character. 
They  are  fomied  by  the  retention  of  sebum  in  the  glands,  the  duct  of  which  h.\s  become  ob- 
literated. 

Diagnosis.  Upon  the  forehead  and  temples  of  young  persons  suffering  from  acne, 
^.amerous  whitish  punctate  elevations  of  the  skin  are  often  present  in  connection  with  come- 
dos and  acne  papules.  These  are  also  distended  sebaceous  glands,  shining  through  the  thra 
epiati-mis,  and  differ  from  milia  only  by  the  fact  that  the  duct  is  not  obliterated.  ^\Tiile 
milia  are  disposed  to  be  permanent,  these  little  glandular  nodules  usually  become  emptied  of 
their  contents  in  a  comparatively  short  time,  even  without  treatment. 

Trf  ktment.     The  simplest  and  best  mode  of  removing  milia  is  to  punrture  the  epi-

deniiis  over  each  one  with  a  sharp  acne  lance,  and  then  to  press  out  the  little  globular  tumor 
by  means  of  a  small  sized  curette.  This  need  not  cause  the  slightest  drop  of  blood  and  is 
sufficient  to  permanently  remove  the  milium.  I  have  never  seen  one  return  after  removal  in 
this  manner. 

CYSTIS   SEBACEA. 

Synonym —  Wen. 

A  sebaceous  cyst  or  wen  is  a  milium  oq  a  larger  scale.  It  is  a  collection  of  sebaceous 
matter  enclosed  by  a  sac  which  has  been  formed  by  a  gi-adual  distention  of  a  sebaceous  gland. 
It  forms  a  prominent  rounded  tumor,  varj-ing  in  size  from  a  pea  to  an  English  walnut.  "When 
small,  wens  are  usuaUy  of  linn  consistence,  and  movable  beneath  the  skin.  When  larger, 
they  are  apt  to  become  somewhat  softer  and  doughy  in  character.  The  skin  over  the  tumor 
is  usually  of  normal  color  and  texture.  It  may  become  somewhat  thinner  when  thegro^vth  is 
large  and  in  exceptional  instances  it  becomes  reddened  by  inflammation,  and  suppuration 
occasionally  occurs.  "Wens  are  usually  single,  but  several  of  varying  size  are  not  infrequently 
met  \v\x\\  upon  the  same  patient.  The  scalp  and  forehead  are  the  favorite  site  of  the  tumors, 
but  they  also  occur  upon  the  back,  the  scrotum  and  other  parts.  A  cyst  occvu-ring  upon 
hairy  portions  of  the  body  usually  becomes  bald  in  a  short  time,  the  hair  bulbs  being  de- 
stroyed by  the  tension  of  the  sldn.  Occasionally  the  duct  of  the  gland  is  not  entirely  obliter- 
ated and  through  this  canal  leading  to  the  cavity  of  the  cyst,  a  portion  of  its  contents  is  from 
time  to  time  extruded,  giving  the  tumor  a  flattened  appearance. 

The  contents  of  sebaceous  cysts  vary  in  character  from  a  soft,  white,  curdy  matter  to  a 
diy,  friable  and  sometimes  extremely  fetid  substance. 

Diagnosis.  A  wen  is  usually  recognized  \vithout  difficulty,  but  a  fatty  tumor  (ade- 
noma) or  even  a  subcutaneous  abscess  might  be  mistaken  for  it,  especially  when  not  occurring 
upon  the  scalp. 

TuKAT.MK.vT.  A  Complete  removal  of  a  sebaceous  cyst  is  usually  not  a  difficult  matter 
if  ordinary  care  is  exercised  in  the  operation.  The  skin  covering  the  tumor  should  first  be 
incised  to  a  sufficient  length  to  allow  the  globular  mass  to  pass  through  readily.  This  can 
then  be  easily  raised  from  its  bed  by  means  of  a  curved  spatida  or  small  spoon  handle,  as 
there  are  usually  no  adhesions,  except  in  cases  where  there  has  been  a  previous  unsuccessful 
operation  or  spontaneous  inflammation  around  the  tumor.  Care  should  be  taken  not  to  cut 
into  the  sac  and  allow  a  portion  of  its  contents  to  escape.  If  the  sac  is  merely  opened  and 
its  cheesy  contents  scraped  or  pressed  out,  a  return  of  the  tumor  may  be  expected.  Our  object 
should  be  to  remove  the  whole  or  greater  portion  of  the  sac,  and  when  this  is  accidentally 
punctured  by  the  knife,  and  the  tumor  becomes  partially  collapsed  through  loss  of  some  of 
its  contents,  it  is  more  difficult  to  get  rid  of  the  entire  growth.  Some  prefer  to  puncture  a 
Aven,  i>ress  out  the  contents  and  destroy  tlio  socretinrr  surface  of  the  ?ac  by  injecting  iodine  or

thiy  until  inflammation  ensues.     Then  a  puncture  of  the  base  of  the  tumor  will  allow  pus  ajiJ 
broken  down  sebaceous  matter  to  escape,  and  a  cure  follows. 

HYPERIDROSIS. 

lI\-Iieridrosis  is  an  affection  in  which  there  is  an  abnormal  functional  activity  of  the 
sweat  glnnds.  Profuse  perspiration  which  follows  vigorous  exercise  or  exposure  to  a  high 
temperature  is  purely  physiological  in  character  and  consistent  with  health.  The  col- 
liquative sweating  of  phthisis  as  also  that  which  is  observed  in  rheumatism,  intermittent 
fever  and  other  febrile  affections,  is  strictly  speaking  an  instance  of  hyperidrosis,  but  is 
usually  not  considered  when  viewing  the  condition  from  a  dermatological  standpoint.  Many 
who  are  otherwise  in  apparently  perfect  health  sweat  excessively  without  apparent  provoca- 
tion, and  are  annoyed  thereby  to  a  greater  or  less  degree.  Corpulent  people,  especially  in 
summer  time,  are  especially  prone  to  a  mild  degree  of  hyperidrosis,  but  some  who  are  not 
particularly  well  nourished  si.ffer  in  like  manner  and  at  various  seasons  of  the  year.  Tlie 
affection  may  occur  in  an  acute  form  and  subside  in  a  short  time,  the  obscure  cause  having 
ceased  to  act,  but  generally  it  is  extremely  chronic,  as  the  disposition  to  the  excessive  secre- 
tion of  sweat  is  not  easily  subdued. 

Hyi^eridrosis  may  be  general  (//.  imi  car  sails)  or  local  in  its  manifestation  {H.  localis). 
Occurring  over  the  whole  surface  of  the  body  it  is  not  usually  severe,  but  when  limited  to 
certain  parts  it  is  much  more  noticeable  and  constitutes  a  not  uncommon  and  an  extremely 
disagreeable  affection.  The  palms,  soles  and  axillae  are  the  parts  which  are  most  apt  to  be 
the  seat  of  the  trouble,  but  the  face  and  the  genital  region  are  not  unfrequently  affected.  In 
rare  cases  hyperidrosis  occurs  in  a  unilateral  form.  One  side  of  the  head,  or  one  of  the  ex- 
tremities, or  even  one-half  of  the  entire  body,  may  be  bathed  in  perspiration,  while  the 
opposite  side  retains  its  natural  condition.  A  story  is  told  of  a  celebrated  young  comedian 
wlio  was  subject  to  unilateral  hyperidrosis  of  the  face.  One  night  he  appeared  upon  the 
stage  as  an  old  man,  the  face  being  made  up  to  suit  the  part.  As  the  play  proceeded  the 
merriment  of  the  audience  became  excessive,  and  the  unusual  and  seemingly  uncalled-for 
shouts  of  laughter  which  greeted  his  acting  surprised  and  peq^lexed  him.  On  retiring  behind 
the  scenes  he  found  that  the  unilateral  iierspiration  had  washed  half  of  the  paint  from  his 
face,  which  had  presented  to  the  audience  the  appearance  of  wrinkled  age  upon  one  side  and 
blooming  youth  upon  the  other. 

Hyperidrosis  of  the  hands  is  not  only  annoying  to  the  patient  himsell'  but  to  those  with 
whom  the  social  custom  requires  him  to  greet  with  a  shake  of  tlie  hand.  A  Ivid  gk)ve  cannot 
be  worn  in  certain  cases  without  becoming  immediately  soaked  through  by  the  increaseil 
secretion,  and  often  the  affection  prevents  the  sufferer  from  following  any  occupation  involv- 
ing the  handling  of  fine  textures.  Frequent  wiping  of  the  hands  does  little  good,  and  m 
social  intercourse  the  consciousness  that  the  hands  are  unpresentable  and  the  consequeiii 
anxiety  of  mind  tend  only  to  increase  the  unfortunate  secretion.

DISEASES  OF  THE  SKIN.— GLANDULAR. 

HjTipridrosis  of  the  feet  is  often  associated  with  a  similar  condition  of  the  hand.^,  out 
either  may  exist  alone,  '\^^len  the  feet  are  theseat  of  the  affection,  the  stoc  kings,  howeTcr 
frequently  changed,  are  kept  moistened  by  the  secretion,  and  even  the  leather  covering  of  the 
feet  becomes  soaked  in  time.  A  disagreeable  odor  is  usually  occasioned  by  the  chemical 
change  which  the  secretion  undergoes. 

Treatment.  The  predisposing  causes  of  hyperidrosis  should  be  diligently  sought  foi 
in  every  case  and  removed  if  possible.  Nervous  derangement  and  an  impaired  circulaiioD 
are  frequently  underlying  conditions  which  demand  the  most  careful  hygienic  treatment. 
Among  the  drugs  which  have  been  recommended  as  cajiable  of  producing  beneficial  results  in 
this  affection  are  atropia  and  ergot.  Small  doses  of  jaborandi  have  also  been  employed  with 
good  effect  in  both  local  and  general  hyperidrosis.  As  it  is  impossible  in  many  cases  to 
determine  the  precise  cause  of  the  disorder,  we  are  generally  forced  to  depend  largely  upon 
external  applications,  many  of  which  give  immediate  relief  and  in  time  subdue  the  excessive 
secretion.  When  the  sweating  is  general  baths  containiug  sea  salt  or  carbolic  acid  may  be 
employed,  or  portions  of  the  body  rubbed  successively  \vith  a  soft  sponge  dipped  in  the  fol-

is  the  subnitrate  of  bismuth  rubbed  well  into  the  skin  after  bathing,  or  dusted  over  the  inside 
of  the  gloves  or  stockings,  llebra  advised  a  plan  of  treatment,  which  if  properly  carried  out, 
usually  affords  immunity  from  the  annoying  secretion  for  a  considerable  time,  if  it  does  not 
effect  a  cure.  This  plan  consists  in  spreading  diachylon  ointment  upon  pieces  of  linen  with 
which  the  lingers  and  toes,  as  well  as  the  rest  of  the  hands  and  feet,  are  carefully  enveloped. 
This  dressing  is  to  be  re-applied  twice  daily  for  a  week  or  two,  the  hands  not  being  washed 
in  the  meantime.  The  application  causes  an  exfoliation  of  the  epidennis,  leaving  the  skin 
soft  and  comparatively  dry. 

BROMIDROSIS. 

Synonym —  Osmidrosis. 
Bromidrosis  is  an  affection  in  which  the  perspiration  is  characterized  by  a  peculiar  and 

(18) 


BROMIBROSIS. 

usually  an  extremely  disagreeable  odor.  The  normal  perspiration  has  always  a  slight  odor 
from  admixture  \vith  the  sebaceous  secretion,  although  this  may  not  be  perceptible  to  the 
average  sense  of  smell,  except  in  summer,  or  after  violent  exercise.  In  disease  the  perspira- 
tion is  frequently  changed  in  character,  and  rheumatism,  intermittent  fever,  scurvy  and  other 
alfections  have  been  supposed  by  some  to  have  each  its  distinct  and  characteristic  odor.  In- 
deed, some  have  claimed  that  the  odor  emanating  from  various  skin  diseases,  notably  small- 
pox, scabies  and  sj'j^hilis,  might  be  utilized  as  a  basis  of  diagnosis.  Certain  persons,  whose 
skin  is  perfectly  free  from  disease,  and  whose  general  condition  is  good,  exhale  from  their 
bodies  a  peculiar  odor  which  seems  to  be  natural  to  them.  It  may  be  constant,  or  occur  only 
in  connection  vdth  mental  excitement,  or  other  unusual  conditions.  The  odor  is  usually  in- 
describable, although  it  has  been  likened  in  certain  instances  to  "violets,"  "pine  apple,"  <tc. 
In  brcmidrosis  the  secieticn  may  exist  in  normal  amount  or  it  may  be  in  excess.  The 
latter  is  commonly  the  case  upon  the  feet  and  in  the  axilla,  in  which  case  we  have  simply 
hyperidiosis  with  a  foetid  odor.  This  odor  may  not  be  due  to  any  change  in  the  composition 
cf  the  perspiratciy  secretion,  but  usually  results  largely  ficm  the  decomposition  of  the 
sweat  which  has  soaked  into  the  clothing  of  the  part.  In  brcmidrosis  of  the  feet  even  the 
shoes  may  become  saturated  with  the  fotil  secretion.  The  peculiar  odor  may  also  be  due  in 
great  part  to  a  peculiar  secretion  of  the  sebaceous  glands  which  becomes  mingled  with  the 
perspiration.  As  the  foetid  secietion  of  brcmidrosis  is  more  irritating  to  the  skin  than  a 
simple  excess  cf  perspiration  we  find  in  this  disease  a  maiked  tendency  cf  the  skin,  especi- 
ally cl  the  leet.  to  become  macerated  and  tender.  Upcn  the  scles  the  epidermis  is  always 
sodden,  and  often  peels  off  in  large  masses,  leaving  an  inflamed  and  often  eczematous  con- 
dition, through  which  locomotion  is  seriously  impaired. 

Treatment.  The  general  treatment  of  brcmidrosis  is  substantially  the  same  as  that 
ol  hjqieridrosis,  since  whatevei'  lessens  the  amount  of  the  secretion  tends  to  diminish  the 
unpleasant  odor.  The  natural  tendency  cf  some  persons  to  secrete  fatty  acids,  which 
give  tc  the  mingled  sweat  and  sebum  a  pungent  if  not  a  disagreeable,  odor  is  extremely 
difficult  to  overcome.  The  more  severe  forms  cf  foetid  sweating  are  fortunately  more  amen- 
able to  treatment,  and  are  often  checked  by  the  adoption  of  such  measures  a.s  promote  the 
general  health  ol  the  person  aflected.  In  the  meantime  a  resort  must  be  had  to  local  and 
more  oi  less  palliative  measures.  Lotions  and  dusting  powders  of  an  antiseptic  character 
have  been  found  most  useful  in  brcmidrosis,  especially  when  the  disease  involves  the  feet, 
as  it  is  most  apt  to  do.  Foi  bathing  the  skin  a  one  per  cent,  solution  (five  grains  to  the 
ounce)  ol  chloral  oi  permanganate  ol  potash  is  both  cleanly  and  beneficial.  It  should  be 
applied  with  as  little  friction  as  possible,  and  allowed  to  dry  upon  the  skin,  or  the  excess  of 
moisture  may  be  removed  by  the  pressure  of  a  soft  warm  cloth.  Ainsworth  recommends  the 
application  of  the  following  powder  :  —

Salicylic  acid    .        .        .  6     "

DISEASES  OF  THE  SKIN.— OLAKDULAR. 

TMn,  of  London,  after  a  careful  study  of  the  subject  of  bromidrosis,  found  the  moist  are 
which  collects  in  a  patient's  stocking  to  be  of  an  alkaline  reaction  and  swarming  with  bac- 
teria. This  fluid  acts  as  an  initant  to  the  skin  and  greatly  aggravates  the  disease.  As  a 
parasiticide  application,  and  one  calculated  to  aUay  the  irritation  of  the  skin,  he  recommends 
the  use  of  boracic  acid.  The  stockings  should  be  changed  tv^'ice  daily  and  the  stocking  feet 
placed  for  some  hours  in  a  jar  containing  a  saturated  solution  of  boracic  acid.  They  are  then 
dried  and  may  be  worn  again,  the  odor  liaving  disappeared.  To  prevent  the  foetid  perspiration 
soaking  into  the  soles  of  the  shoes,  and  thus  giving  rise  to  a  pennanent  stench,  cork  soles 
are  to  be  worn  during  the  day  and  soaked  over  night,  like  the  stocking  feet,  in  the  jar  of 
boracic  acid. 

Chkomidrosis  is  a  term  applied  to  a  discoloration  of  the  sweat.  This  may  be  blackish 
{melanidrosis)  and  occur  about  the  eyes  of  hysterical  women,  bluish  {cyanidrosis)  and  occur 
upon  the  body  in  sufficient  amount  to  stain  the  underclothing,  or  red  {hematidrosis)  in  which 
case  there  is  usually  an  extravasation  of  blood  into  the  sweat  glands. 

Anidrosis  signifies  an  absence  of  perspiration.  It  may  residt  from  disease  of  the  skin, 
as  in  ichthyosis,  or  from  internal  disease,  as  in  cases  of  diabetes.  For  the  relief  of  this  con- 
dition the  internal  use  of  pilocarpine,  or  a  resort  to  the  Turkish  bath,  would  suggest 
itself.

CHAPTER  II.  i 

INFLAMMATORY    DISEASES. 

This  class  of  skin  diseases,  including  those  in  which  inflammarion  is  the  essential  element, 
ranks  first  in  point  of  size  and  importance.  It  embraces  most  ol  the  common  affections  of 
the  skin,  and  a  thorough  api^-eciation  of  the  nature  and  treannent  of  these  will  enable  the 
physician  to  claim  the  mastery  of  more  than  one  half  of  Demiatology. 

Some  wTiters  have  separated  the  hypersemic  affections  from  those  in  which  exudation  is 
present,  but  in  practice  it  is  by  no  means  easy  to  keep  them  apart.  A  simple  erythema  w'uh. 
desquamation  merges  gradually  into  the  mildest  form  of  erji;hematous  eczema,  and  in  many 
cases  it  is  impossible  to  say  where  the  dividing  line  should  be  drawn.  Since  an  erythema 
which  is  not  e\anescent  in  character  is  usually  accompanied  by  redness,  heat,  ])ain  and  swell- 
ing in  at  least  a  mild  degree,  it  seems  botli  jiroper  and  desirable  to  include  the  purely  hyper- 
lemic  with  the  exudative  affections  under  the  same  head. 

The  exanthemata  naturally  fall  in  this  class,  but  as  they  are  fully  described  in  all  works 

on  general  medicine,  it  is  unnecessary  in  a  treatise  on  skin  diseases  to  devote  much  space  to 

their  consideration.  ;

RUBEOLA. 

St/ a  onyms — MorlnlU — Mensles. 

Measles  is  a  highly  contagious  febrile  affection,  the  chief  symptoms  of  which  are  a  ca- 
tarrhal condition  of  the  respiratory  passages  and  a  characteristic  exanthem.  It  is  commonly 
observed  among  children,  and  in  an  epidemic  form.  Like  the  other  exanthemata,  it  is  not 
likely  to  occur  but  once  in  a  lifetime  ;  but  exceptional  cases  are  not  infrequent  where  re])"ated 
attacks  in  the  same  person  have  been  noted  by  i)hysicians  who  would  not  be  likely  to  nii.stake 
the  nature  of  the  disease.  Measles  is  more  contagious  than  small-pox  or  scarlet  fever,  and 
even  on  i  he  first  day  of  the  fever  infection  is  ai)t  to  be  transmitted  to  unprotected  jiersons 
who  come  near  the  patient.  The  period  of  incubation  is  variable  in  duration,  ranging  from 
one  to  three  weeks,  during  which  period  the  patient  experiences  little  if  any  discomfort. 
The  attack  begins  suddenly  with  an  imtation  of  the  mucous  membrane  of  the  nose  and  suf- 
fusion of  the  eyes,  a  tendency  to  sneezing,  a  slight  thin  nasal  discharge  and  occasional  epis- 
taxis.  The  tem])erature  which  usually  rises  to  103-104°  F.  at  the  outset,  declines  on  the  second 
or  third  day,  but  rises  again  with  the  outbreak  of  the  eruption.     This  generally  occurs  on 

(21) 


DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

the  fouitb  day,  sometimes  on  the  third,  but  occasionally  on  the  fifth  day  or  even  later.  It  is 
lii-st  noted  upon  tlie  forehead  and  temples,  from  which  it  quickly  extends  down  upon  the  face, 
and  in  two  days  usually  covers  more  or  less  of  the  trunk  and  extremities.  In  its  natural 
course  the  fever  now  abates,  the  catarrh  and  cough  are  lessened,  the  rash  gradually  fades, 
and  in  less  than  two  weeks  the  skin  presents  a  characteristic  branny  desquamation. 

The  eruption  is  at  first  of  a  dusky  hue  and  of  a  maculo-papular  character.  The  lesions 
are  numerous  and  closely  aggregated  over  limited  portions  of  skin,  darkest  in  the  centre,  but 
disapjiearing  entirely  under  pressure  of  the  finger.  Tliey  are  sometimes  crescentic  in  form, 
but  usually  appear  as  a  deep  red  and  fine  mottling  ujion  a  swollen  and  erji;hematous  surface. 

The  disease  may  occur  without  the  catarrhal  symptoms,  and  on  the  other  hand  without 
the  appearance  of  anj'  rash,  or  one  so  slight  as  to  escape  observation.  In  rare  instances, 
which  occur  chietiy  among  poorly  nourished  and  weakly  children,  the  eruption  becomes 
hemorrhagic  in  character,  and  the  disease  assumes  a  malignant  fonn  (Black  Measles).  When- 
ever the  eniptiou  is  very  well  marked  there  is  liable  to  be  a  development  of  fine  miliary  ves- 
sicles  upon  some  portions  of  the  skin.  Occasionally  bullse  form,  and  frequently  urticaria 
appears  as  a  complication  of  the  rash. 

RUBELLA. 

Synonyms — Rotlum —  German  Measles. 

This  affection  is  one  v>-hich  was  formerly  regarded  as  a  mild  form  of  rubeola,  and  even 
now  is  often  mistaken  as  such.  There  is  little  doubt,  however,  that  it  is  a  distinct  affection, 
and  that  an  attack  of  the  former  does  not  exempt  a  patient  in  any  degree  from  an  attack  of 
the  latter  affection,  or  vice  versa. 

Tlie  sj-mptoms  of  rubella  are  similar  to  those  of  rubeola,  though  far  less  marked.  The 
prodi-omic  fever  is  very  slight  when  present,  never  more  than  twenty-four  hours  in  duration, 
and  frequently  the  rash  is  the  first  sjTnptom  of  the  affection.  There  may  be  a  slight  coryza, 
with  redness  of  the  conjunctiva,  but  rarely  sufficient  to  occasion  much  annoyance.  A  sore 
throat  is  a  more  common  symptom,  and  one  which  sometimes  persists  after  the  rash  has  dis- 
appeared. The  eruption  consists  of  numerous  minute  red  papules,  of  a  much  brighter  hue 
than  is  seen  in  measles,  and  exhibiting  a  tendency  to  coalesce  and  form  smooth  red  patches. 
It  fades  in  two  or  three  days  and  is  followed  by  slight  desquamation. 

SCARLATINA. 

Synonym — Scarlet  Fever. 

Scarlatina  is  an  acute  contagious  disease  characterized  by  fever,  sore  throat,  and  a  bright 
red  erj'thematous  eruption. 

The  period  of  incubation  is  quite  variable,  and  unlike  measles,  the  patient  is  not  likely 
to  infect  others  until  the  eruption  has  become  well  developed.     The  scarlatinal  poison  is  less 

(22) 


SCAIiLATIN-A. 

volatile  than  that  of  measles,  and  is  capable  of  remaining  a  long  time  in  clot  bin"-  and  other 
articles  which  have  been  in  close  proximity  to  a  scarlet  fever  patient,  and  this  fact  -ndll  on- 
■doubtedly  account  for  the  uncertainty  of  the  period  of  incubation. 

The  attack,  which  is  always  sudden,  is  usually  characterized  by  chills,  vomitin"-  and 
swelling  of  the  throat.  The  tongue  is  at  first  coated,  but  in  two  or  three  days  be"-ins  to 
assume  a  characteiistic,  bright  red  'strawberry"  appearance.  The  fever  is  of  high  grade, 
and  may  reach  105°,  or  more,  on  the  lirst  day,  the  pulse  being  rapid  in  character,  and  the 
skin  extremely  dry  and  hot.  It  sulfers  no  abatement,  but  on  the  other  hand,  may  increase 
with  the  development  of  the  exanthem. 

The  eruption  usually  appears  upon  the  second  day.  It  is  commonly  noted  first  upon  the 
neck  and  upper  portion  of  the  chest,  from  which  it  rapidly  spreads  upon  the  trunk  and  ex- 
tremities, reaching  its  full  development  upon  the  third  or  fourth  day.  With  the  exception 
■of  a  bright  flush  upon  the  cheeks,  the  face  remains  unaffected  at  the  outset  of  the  eruption. 
The  rash  is  at  first  punctate  in  character,  the  red  points  being  numerous  and  closely  set,  but 
hy  degrees  these  coalesce  and  fonn  laige  patches  of  imifonu  redness.  Upon  the  neck  and 
«hest  they  occasionally  become  slightly  vesicular.  Upon  the  fourth  or  fifth  day  the  rash 
usually  begins  to  fade,  and  in  ten  or  twelve  days  has  completely  disappeared,  if  the  case  is 
typical  in  its  course.  A  well  marlvPd  desquamation  of  the  greater  portion  of  the  body  then 
takes  place  and  continues  during  the  period  of  convalescence.  The  flakes  of  epidermis  may 
be  small  though  rarely  furfuraceous  as  in  measles,  but  generally  they  are  of  considerable 
size,  especially  upon  the  hands  and  feet.  In  some  cases  the  nails  and  hah-  fall  after  a  severe 
attack  of  scarlatina.  At  the  commencement  of  desquamation,  and  sometimes  earlier  in  the 
course  of  the  disease,  the  kidneys  are  notably  affected,  and  albumen  appears  in  the  urine  in 
•considerable  quantity. 

Scarlet  Fever,  with  all  the  usual  symptoms  except  the  eruption,  may  occur,  especially  in 
adults.  Althoitgh  the  disease  occurs,  as  a  rule,  but  once  in  a  lifetime,  it  is  not  imcommon 
for  some  physicians  and  nurses  to  be  affected  with  sore  throat  as  often  as  they  are  called 
*ipon  to  attend  a  case  of  scarlatina. 

There  is  a  great  variation  in  the  severity  of  the  disease  among  individuals  and  in  differ- 
•ent  ei)idemics.  While  one  child  may  have  scarlet  fever  and  scarcely  be  aware  of  the  fact, 
another  may  have  a  malignant  form,  with  terrible  throat  symptoms  and  hemorrhagic  erup- 
tions, or  even  die  before  the  rash  has  had  time  to  appear. 

L>iAti>rosis.  As  scarlet  fever,  measles  and  rubella  do  not  always  occur  in  a  typical 
ionn,  a  difficulty  in  diagnosis  is  very  apt  to  arise,  especially  when  the  case  happens  to  be  a 
sporadic  one.  The  features  of  the  three  diseases,  which  have  been  very  briefly  mentioned, 
must  always  be  taken  into  consideration  as  a  basis  of  diagnosis,  but  experience  \vill  generally 
be  found  to  be  the  only  reliable  guide.  For  convenience  of  reference  the  following  table^ 
arranged  by  Liveing,  is  appended : —

Treatment.  Typical  cases  of  these  three  affections  usually  run  their  course  w  ithout  re- 
quiring any  inteference  on  the  part  of  the  physician.  In  the  mildest  cases,  however,  a  strict 
professional  watch  care  is  demanded  in  order  to  detect  all  threatening  complications  at  the 
earliest  i)ossible  moment.  On  prophylactic  grounds,  complete  isolation  of  the  patient  is 
necessary,  and  after  convalescence  a  thorough  fumigation  of  the  apartment,  the  bedding  and 
clothing  is  advisable.    This  is  especially  so  in  case  of  scarlatina. 


VARIOLA. 

Synonym — Small  Pox. 

Variola  is  ordinarily  the  most  severe  and  the  most  dreaded  of  the  acute  exanthemata. 
Thanks  to  one  of  the  most  brilliant  achievements  of  medical  science,  this  terrible  scourge  of 
former  times  can  now  be  held  in  check,  and  measures  instituted  which  ^vill  exempt  all  intel- 
(igent  and  unbiased  me.'ubprs  of  n  community  from  its  direful  attacli. 

The  period  of  inniliaJioii  is  ii.siially  from  ten  to  iliirtet>n  days,  during  which  siifjhr  luii 

(•--4) 


VARIOLA . 

tjuor,  with  pain  in  the  head  and  back,  may  be  experienced.  The  initial  and  prodromal  sia^e 
is  usually  iishered  in  by  a  violent  rigor  or  repeated  chills.  This  is  followed  by  a  well-marked 
fever,  severe  headache,  and  aching  pain  in  the  lumbar  region  and  vomiting.  At  this  time  a 
diffuse  erythematous  rash  may  appear  upon  portions  of  the  body,  or  a  petechial  eruption  be 
(observed  upon  the  lower  portions  of  the  abdomen,  genitals  and  inner  surface  of  the  tliighs. 
These  disappear  before  the  occurrence  of  the  characteristic  exanthem  whirh  commonly  makes 
its  api)eurance  on  the  third  day.  This  begins  upon  the  scalp  ana  rorehead  in  the  form  of 
small  pale  red  and  slightly  elevated  macules.  These  qmckly  ap])ear  upon  the  face,  and  in  a 
few  hours  are  apparent  upon  the  body  and  extremities,  the  legs  :ind  feet  being  the  most 
affected.  In  about  two  days  these  lesions  have  devoped  into  hard  shotty  pap-ales,  which  on 
the  sixth  day  of  the  disease  become  conical  and  present  minute  vesicles  at  their  apices.  On 
the  eighth  day  these  vesicles  are  pea-sized  and  hemispherical  in  form.  A  peculiar  depression 
in  the  centre  ol  most  of  these  vesicles  now  takes  place  which  is  quite  characteristic  of  the 
disease.  On  the  ninth  day  of  the  disease  the  lesions  become  pustular  in  character  and  a 
congested  halo  appears  around  each.  ^VTien  the  lesions  are  closely  aggregated  a  considerable 
tumefaction  of  the  skin  ensues,  with  frequent  coalescence  of  the  pustules.  The  face  is  espe- 
cially apt  to  present  this  confluent  form  of  the  eruption,  and  the  swelling  becomes  so  great 
thni  the  patient  is  unrecognizable.  Owing  to  the  successive  development  of  the  lesions  upon 
'1  liferent  portions  of  the  body  the  eruj^tion  is  generally  observed  to  be  pustular  upon  the  face, 
while  it  is  only  in  the  vesicular  stage  upon  the  lower  extremities.  Even  when  the  eruptiou 
is  quite  discrete  upon  the  trunk,  the  hands  and  feet  are  usually  thickly  covered  and  intensely 
swollen.  The  mucous  membrane  of  the  oral  cavity,  and  particularly  the  hard  and  soft  palate 
present  an  eruption  somewhat  similar  to  and  coincident  with  that  upon  the  skin. 

The  temperature,  which  may  have  reached  104«  in  the  initial  stage,  falls  suddenly  with 
the  outbreak  of  the  eruption  to  nearly  normal  degree,  and  the  other  symptoms  likemse  abate, 
leaving  the  patient  in  a  comparatively  comfortable  condition.  With  the  development  of 
pustules  a  secondary  or  suppurative  fever  ensues,  accompanied  by  headache,  and  not  infre- 
quently delirium.  The  pustules  of  small-pox,  which  are  at  first  umbUicated,  like  the  pre- 
ceding vesicles,  may  become  rounded  from  a  loosening  of  the  trabecular  bands,  which  have 
produced  the  central  depression.  After  an  existence  of  two  or  three  days  a  partial  desiccation 
takes  place,  with  an  exudation  of  a  viscid,  honey -like  substance  upon  the  surface  of  the  pus- 
tules. Gradually  these  become  converted  into  brownish  crusts,  the  inflammatory  swelling  of 
the  skin  lessens  in  a  notable  degree  and  the  fever  subsides.  The  crusts  loosen  and  fall,  leav- 
ing a  dull  red  mark,  the  color  of  which  varies  according  to  the  suri'ounding  temperature  and 
the  activity  of  the  circulation.  With  the  drying  and  fall  of  the  crusts  intense  itching  is 
commonly  experienced  by  the  patient.  In  uncomplicated  variola  the  course  of  the  disease  is 
usually  four  to  six  weeks.  In  complicated  cases,  or  in  those  rare  and  malignant  cases  where 
hemorrhage  takes  place  in  the  pustules,  the  duration  of  the  disease  and  convalescence  is 
greatly  prolonged  unless,  as  frequently  happens,  death  cuts  short  its  course.

tibUity  is  slight,  or  in  those  who  have  been  partially  protected  by  inoculation  or  vaccination, 
is  comiiionly  Ivnown  as  varioloid  or  inodiiied  small  pox.     It  is  by  no  means  a  distinct  affection. 

The  most  strildng  feature  of  varioloid  is  its  tendency  to  run  an  irregular  course  as  re- 
gards the  diiiution  of  its  stages  and  the  character  of  its  symptoms.  The  eruption,  which  in 
variola  vera  appears  uniformly  on  the  third  day,  may  appear  on  the  first  or  seco).'5  in  vario- 
loid, or  be  unusually  delayed.  It  often  appears  first  upon  the  trunlc  instead  of  upr//  the  face, 
often  in  successive  crops,  and  the  lesions  do  not  run  such  a  I'egular  course  as  do  thof/j  of  typi- 
cal small  pox.  Frequently  the  lesions  are  absorbed  before  reaching  the  pustular  stage,  and 
again  they  may  run  such  a  rapid  course  that  desiccation  begins  on  the  seventh  or  eighth  day. 

DiAGXOSis.  The  diagnosis  of  variola  or  varioloid  must  always  rest  upon  a  familiarity 
wth  the  sjTnptoms  of  the  disease  and  a  very  careful  examination  of  the  case.  ^^Tien  doubt 
exists  it  is  advisable  to  visit  the  patient  repeatedly  at  short  intervals,  and  to  avoid  g'.nng  anv 
hasty  opinion. 

TuEATMEXT. — It  has  been  said  of  Small -pox  that  in  its  mildest  forms  medi.inal  treat 
ment  is  scarcely  called  for,  in  the  severest  it  is  useless,  and  indeed  under  any  ciicumstances 
it  has  but  little  influence  over  the  coiirse  of  the  disease.  Nevertheless  there  is  much  that  can 
be  done  in  its  treatment  ^nth  a  %iew  to  alleviating  the  sufferings  of  the  patient,  guarding 
against  threatening  complications,  and  preventing,  to  a  certain  extent,  the  unsightly  pitting 
of  the  face,  which  is  often  a  life-long  indication  that  the  bearer  has  suffered  from  small-pox. 

There  is  no  specific  remedy  as  yet  discovered  which  will  influence  the  course  of  the  dis 
ease,  and  treatment  of  the  various  sjonptoms  and  complications  as  they  present  themselves  is 
the  usual  duty  of  the  physician.  In  no  disease  is  good  nursing  more  essential,  and  attention 
to  minute  details  which  contribute  to  the  comfort  of  the  patient  will  often  turn  the  scale  be- 
tween life  and  death.  The  older  plans  of  treatment  by  sweating,  purging  and  blood-letting 
have  fortunately  now  but  an  historical  interest,  and  have  been  supplanted  by  various  hygi- 
inic  Pleasures,  such  as  keeping  the  patient  in  a  cool,  dark  and  well  ventilated  aiiartment,  and 
such  treatment  as  is  calculated  to  lessen  cutaneous  inflammation  and  to  support  the  strength 
of  the  patient.  The  free  use  of  cold  water  and  acid  drinks  to  allay  thirst,  and  the  applica- 
tion of  cold  compresses,  or  resort  to  cool  baths  oi-  sponging,  are  highly  recommended.  The 
application  of  caustic  to  the  pustules,  or  the  use  of  mercurial  plasters  and  solutions  of  iodine 
or  nitrate  of  silver,  with  a  view  to  prevent  pitting  of  the  face  is  of  doubtful  value,  and  cer- 
tainly inferior  to  an  attempt  to  control  the  inflammation  and  prevent  pus-formation  in  the 
deeper  portion  of  the  skin  by  the  use  of  cold  compresses. 

While  little  can  be  done  through  medical  skill  in  the  actual  treatment  of  a  case  of  small- 
pox, much  can  be  accomplished  in  preventing  the  spread  of  infection,  through  a  complete 
isolation  of  the  patient  from  the  very  outset  of  the  attack  to  the  close  of  convalescence  and 
tlie  careful  disinfection  or  destruction  of  all  clothing,  bedding  and  other  ai-ticles  whicli  might 
tran.smit  the  disease  to  others.  The  greatest  good,  however,  to  the  greatest  number,  results 
I'loni  the  prophylactic  measure  which,  if  faithfully  carried  out  in  every  community,  would 
sooner  or  later  annihilate  small-pox.  It  is  scarcely  necessary  to  add  that  the  measure  referred 
to  is  general  vaccination.

VACCIIflA. 
VACCINIA. 

Sy7t.onym —  Coxo-pox. 

A  disease  identical  with  or  analagous  to  variola  occurs  ia  several  species  of  our  largei 
domestic  animals,  and  is  characterized  by  a  limited  eruption  of  pustules.  These  commonly 
occur  about  the  fetlocks  in  horses,  and  upon  the  udder  and  teats  in  the  cow.  Vacciuatiou, 
or  the  inoculation  of  cow-pox  lymph,  produces  a  mild  disease  in  the  human  spec'es,  which 
has  been  found  to  furnish  a  certairi  degree  of  immunity  from  small-pox.  Vacciuia  may  be 
produced  in  the  human  subject  either  from  lymph  taken  dh-ectly  from  the  heifer  (bovine 
virus),  or  from  a  vaccine  vesicle  thus  produced  (humanized  virus),  and  transmitted  from  one 
person  to  another  through  many  generations.  The  dried  crust  of  the  vaccine  pustule  may 
also  be  used  to  furnish  the  necessary  virus  for  vaccination. 

In  the  performance  of  this  simple  operation  it  is  only  necessary  to  gently  remove  by 
scraping  the  horny  layer  of  the  epidermis  at  a  given  point  and  apply  the  lymph  to  tlie 
abi'aded  surface.  To  effect  this  a  clean  needle  may  be  employed  and  a  number  of  crosscil 
scratches  made  upon  the  surface  of  the  skin,  or  what  is  preferable,  an  abrasion  made  no  larger 
than  a  small  split  pea,  by  means  of  a  dull  lancet  or  clean  pen-knife  blade.  It  is  neither 
necessary  nor  advisable  to  draw  blood  in  the  operation,  and  if  care  is  taken  a  sleeping  infan; 
can  often  be  vaccinated  without  being  awakened,  or  without  being  made  to  cry  if  awake 
The  left  arm,  at  the  insertion  of  the  deltoid  muscle,  is  the  site  commonly  selected,  and  from 
one  to  three  abrasions  may  be  made.  One  vesicle  running  a  typical  coui-se  will  often  afford 
complete  protection  for  many  years,  but  three  vesicles  will  aiford  a  more  certain  immunity. 

The  development  and  course  of  the  vaccine  vesicle  is  strikingly  similar  to  that  observed 
in  the  cutaneous  lesions  of  variola.  With  the  exception  of  the  mark  which  simple  scratching 
of  the  skin  would  produce,  nothing  peculiar  is  noted,  as  a  rule,  nntU  the  third  day.  A  slight 
redness  and  swelling  of  the  wounded  skin  then  becomes  noticeable.  On  the  following  day 
the  epidermis  is  slightly  elevated  by  an  effusion  of  clear  serum,  and  the  vesicle  thus  produced 
steadily  increases  in  size  from  day  to  day,  and  becomes  depressed  in  the  centre.  The  outline 
of  this  lesion  is  circular,  elongated,  or  iiTegular,  in  accordance  with  the  shape  of  the  abrasion 
previously  made.  The  vesicle  attains  its  greatest  development  upon  the  seventh  or  eighth 
day.  The  liquid  contents,  owing  to  the  peculiar  fan-like  mesh-work  of  the  interior  of  the 
vesicle,  do  not  escape  readily  if  the  epidermis  is  pricked,  but  ooze  out  slowly  in  the  form  of 
a  mucilaginous  drop.  About  the  ninth  day  the  clear  serum  appears  turbid,  the  vesicle  rap- 
idly becomes  pustular-  in  character,  and  considerable  redness  and  swelling  is  noted  in  tht 
immediate  vicinity.  Its  appearance  now  is  indeed  like  "a  pearl  upon  a  rose-leaf."  By  tht 
eleventh  or  twelfth  day  the  vaccine  pustule  has  become  yeUowin  hue,- and  in  the  umbilicated 
portion  a  crust  has  begun  to  form.  With  the  development  of  the  areola  more  or  less  fevei 
and  constitutional  disturbance  is  noted,  and  when  several  vesicles  are  present,  the  local  paia 
and  discomfort  is  usually  considerable.     From  the  swollen  inflammatory  patch  upon  whicL

the  lesions  are  seated,  a  dermatitis  may  extend  down  upon  the  arm  or  into  the  axilla,  espe 
cially  if  external  violence  lias  been  encountered,  and  occasionally  a  severe  and  even  alarming 
erysipelas  may  develop.  Commonly  the  local  and  general  symptoms  subside  with  the  desic- 
cation of  the  pustule.  A  dark  or  mahogany  colored  crust  gradually  forms  and  falls  about 
the  nineteenth  or  twentieth  day,  leaving  a  scar  which  is  at  first  red,  but  which  in  time  be- 
comes white,  depressed  and  foveolated. 

In  connection  ^nth  vaccination,  a  number  of  so-called  vaccinal  eruptions  are  liable  to 
make  their  appearance  as  a  direct  or  indirect  result  of  the  operation.  In  certain  cases  vesico- 
pustules  form  not  only  at  the  point  of  introduction  of  the  vaccine  virus,  but  in  its  immediate 
vicinity,  and  occasonally  a  general  eruption  of  similar  lesions  is  noted.  When  the  vaccine 
vesicle  is  at  its  height,  it  is  not  unusual  for  erythematous  macules  to  appear  upon  the  arm  or 
other  portions  of  the  body,  and  even  the  papules  of  multiform  erythema  or  an  acute  eiiijition 
of  urticaria  may  occur  at  this  time. 

As  an  incidental  result  of  the  constitutional  disturbance  attending  the  development  of 
the  vaccine  vesicle,  eczema,  psoriasis  and  other  cutaneous  affections  may  be  induced  whenever 
a  pi  edisposition  to  their  occurrence  already  exists.  There  is  no  ground  whatever  for  the  be- 
lief entertained  sometimes  by  the  laity  that  these  affections  are  transmitted  by  means  of  the 
vaci  ine  lymph.  It  is  true  that  syphilis  may  be  and  has  been  repeatedly  transmitted  through 
:he  use  of  Ij-mph  mixed  with  blood,  or  a  crust  taken  from  the  arai  of  a  sjiihilitic  infant,  but 
in  the  great  majority  of  cases  where  an  outbreak  of  syphilis  appears  shortly  after  vaccination 
the  disease  is  hereditary  in  nature,  and  the  appearance  of  its  cutaneous  manifestations  is 
merely  evoked  by  the  vaccinal  disease. 

VARICELLA. 

Synonym —  Chicken-Pox. 

Varicella  is  a  well-known  exanthematous  affection  of  infancy  and  childhood.  The  name 
suggests  a  relationship  to  variola,  or  small-pox,  and  there  exists  indeed  a  resemblance  be- 
teen  the  two.  Until  the  inoculation  of  small-pox  prevailed  in  Europe,  varicella  w  as  regarded 
as  a  mild  form  of  this  disease,  and  its  history  is  intimately  associated  with  that  of  variola. 

At  the  beginning  of  the  eighteenth  century  Lady  Wortley  Montagu,  the  wife  of  the 
British  Ambassador  at  Constantinople,  became  acquainted  with  the  practice  of  inoculating 
small-pox  in  order  to  lessen  the  severity  of  the  disease,  and  having  subjected  her  own  chil- 
dren to  the  operation,  advocated  the  practice  with  such  earnestness  that  it  soon  prevailed  not 
only  in  England  but  throughout  Europe.  It  was  at  this  time  that  the  attention  of  physi- 
cians became  directed  to  the  study  of  varicella,  and  the  question  of  its  specific  nature 
assumed  a  vital  importance  in  determining  the  value  of  inoculation.  This  practice,  so  start- 
ling an  innovation  upon  established  custom,  naturally  met  with  opposition.  Its  opponents, 
observing  that  patients  after  having  contracted  (he  disease  by  inoculation  were  subsequently 
attacked  with  what  they  cnnsidcn d  to  bo  smnll-pox.  claimed  that  inoculation  possesecd  no 
prophylactic   value.      Its   .-iipiioiteis.   on    ilic   otlicr   luiiid,  claimed   that    the   pustular  and 


VARICELLA . 

vesicular  eruptions  sometimes  occurring  after  small-pox  were  not  cases  of  true  variola,  but 
distinct  affections,  to  which  they  gave  the  names  varioloid  and  varicella.  After  Jenner  s  discovery 
of  vaccination  the  controversy  respecting  the  identity  of  variola  and  varicella  raged  more 
fiercely  than  ever.  At  the  present  day  there  are  none  in  the  medical  profession  who  claim 
that  varioloid,  or  the  modified  form  of  small-pox  which  sometimes  occurs  after  vaccination, 
is  distinct  from  variola.  As  to  varicella,  however,  the  majority  of  physicians,  who  are  able 
to  pass  judgment  on  the  question,  are  agreed  that  it  is  a  distinct  specific  disease. 

Varicella  is  pre-eminently  a  disease  of  childhood,  and  is  very  seldom  met  with  in  adult 
life.  It  is  rarely  if  ever  seen  twice  upon  the  same  individual,  although  an  attack  of  mild 
small-pox  or  varioloid  may  either  precede  or  follow  the  eruption.  The  serum  contained  in 
the  vesicles  is  not  readily  inoculable,  and  the  eruption  has  no  prophylactic  or  modifying  in- 
fluence over  future  attacks  of  small-pox. 

Varicella  occurs  sporadically  and  in  epidemic  form.  In  large  cities  cases  are  always  to 
be  found,  and  epidemics  of  this  disease  occur  with  far  greater  frequency  than  do  thosp  of 
small-pox.  Some  claim  that  the  disease  is  not  contagious,  and  assert  that  its  occurrence 
among  several  children  of  a  family  is  merely  the  result  of  epidemic  influence.  It  certainly 
does  not  appear  to  be  as  contagious  as  the  other  exanthemata.  I  have  knowTi  three  out  of 
five  young  children  to  be  affected  in  one  household  while  the  other  two  escaped.  The  period 
of  inoculation  is  supposed  to  be  longer  than  that  of  small-pox  or  measles.  During  this 
period  the  child  may  evince  some  signs  of  languor,  but  generally  there  is  only  a  slight  fever  of  a 
few  hours'  duration  preceding  the  eruption,  and  very  frequently  the  eruption  itself  is  the  firs1> 
indication  that  the  child  is  not  in  perfect  health.  The  eruption  at  the  outset  presents  small  red 
macules  or  slightly-elevated  papules  upon  the  body,  and  shortly  after  upon  the  face  and  ex- 
tremities. In  a  few  hours  a  minute  vesicle  is  noted  in  the  centre  of  each  i-ed  macxde,  its 
shape  varying  in  different  cases,  being  either  conical  or  hemispherical,  and  usually  from  a 
pin-head  to  a  small  pea  in  size.  The  vesicles  are  disseminated  and  vary  in  number  from  a 
few  score  to  several  hundred.  They  are  quite  superficial,  covered  by  a  tense  layer  of  epi- 
dermis, and  surrounded  usually  by  a  naiTow  zone  of  inflammatory  redness.  The  contained 
fluid  is  clear,  colorless,  or  slightly  tinged  with  yellow,  and  of  an  alkaline  reaction,  differing 
in  this  regard  from  the  acid  serum  of  sudamina.  The  vesicles  after  the  first  day  may  appear 
cloudy,  but  they  never  become  purulent.  The  fever  subsides  on  the  third  or  fourth  day, 
unless  kept  up,  as  is  often  the  case,  by  successive  crops  of  vesicles.  These  may  become 
flaccid  through  absorption  of  their  contents  when  one  or  two  days  old,  or  they  may  burst 
from  excessive  distension  or  be  scratched  by  the  patient,  in  which  case  they  dry  in  the  centre- 
and  form  yellowish  or  bro\vnish  thin  homy  crusts.  At  this  stage  new  papular  lesions  may 
appear,  and  aborting  in  their  course,  fail  to  become  vesicular.  Some  of  the  vesicles  enlarge 
by  peripheral  extension  and  form  bullae,  which  are  umbilicated  when  the  centre  of  the  vesicle- 
has  begun  to  dry.  The  crusts  fail  in  a  few  days  or  are  scratched  off  by  the  patient  in  his- 
endeavors  to  alleviate  the  pruritus  or  burning  of  the  skin,  which  is  alwajs  present  in  greatc;- 
or  less  degree.      Beneath  is  left  a  small,  circular  and  slightly-depressed  patch  of  reddened

whiteness  and  softness. 

The  diagnosis  of  varicella  is  easily  made  if  the  eruption  is  seen  at  the  outset.  The  red 
papules  noticed  on  the  child's  body  or  neck  on  the  first  day  are  suggestive  of  mosquito  bites, 
and  are  frequently  mistaken  for  them.  The  development  of  vesicles,  however,  shows  that 
the  eruption  is  either  chicken-pox  or  the  vesicular  stage  of  mild  small-pox.  If  an  epidemic  of 
variola  is  in  progress  the  diagnosis  of  the  case  becomes  a  matter  of  considerable  importance, 
and  an  error  may  prove  unfortunate  for  both  patient  and  physician.  Although  variola  is  as 
a  rule  a  far  more  severe  disease  than  varicella,  it  may  run  an  extremely  mild  course,  and  does 
so  frequently  when  modified  by  a  previoiis  vaccination.  In  such  a  case  the  diilerential  diag- 
nosis is  not  always  easy,  but  the  chief  points  upon  which  it  may  be  established  will  be  seen

ERYTHEMA    SIMPLEX. 

This  is  a  common  and  usually  an  insignificant  affection  resulting  from  a  great  variety  of 
causes,  and  rarely  demanding  active  treatment.  It  consists  in  an  eruption  of  bright  red 
patches,  which  gradually  cliang'^  to  a  duller  hue.  They  are  circular  or  irregular  in  outline, 
of  variable  size,  and  occur  upon  various  portions  of  the  body.  These  patches  are  the  result 
of  an  active  or  passive  dilatation  of  the  capillary  vessels,  and  usually  run  an  acute  course. 
The  afl"ection  may  be  idiopathic  and  result  from  the  action  of  heat  or  cold  upon  the  skin, 
from  friction,  pressure  or  other  external  in-itating  agents,  or  it  may  be  symptomatic  of  some 
internal  disorder.     It  frequently  occurs  among  infants  and  young  children  as  the  result  of

ERYTHEMA  a  IMP  LEX. 

gastric  or  intestinal  disturbance,  and  in  adults  is  not  infrequently  due  to  the  ingestion  ol 
certain  drugs  or  unusual  articles  of  food. 

Diagnosis.  Simple  erj-thema  is  not  apt  to  be  mistaken  by  the  physician  for  any  other 
form  of  skin  disease,  but  the  significance  of  the  eruption  is  not  always  appreciated.  If  care- 
fully studied  it  may  serve  to  give  a  clue  to  some  severe  and  impending  constitutional  disease. 
For  instance,  a  peculiar  erj-thematous  rash  occurring  upon  the  extensor  surfaces  of  the  ex- 
tremities, especially  about  the  joints,  is  sometimes  a  j^rodrome  of  variola. 

When  erythema  occurs  in  the  f  onn  of  numerous  small  circular  spots  upon  the  trunk  or 
extremities,  it  has  been  designated  as  roseola.  This  form  may  be  due  to  dental  or  gastro- 
intestinal irritation,  or  it  may  appear  as  the  earliest  cutaneous  manifestation  of  constitutional 
syphilis.  In  such  a  case  the  term  erji;hematous  or  macular  syphilide  is  preferable  to  the  old 
expression,  syjohilitic  roseola. 

In  \dew  of  tlie  prevailing  tendency  to  depart  from  the  Willanic  or  lesional  classification 
of  skin  diseases,  the  terai  erythema  must  be  regarded  as  a  mere  symptom  rather  than  as  an 
independent  disease,  and  the  duty  of  the  physician  is  to  diagnosticate  between  the  multitude 
of  causes  which  may  give  I'ise  to  the  cutaneous  congestion. 

Treatment.  To  determine  whether  the  congestion  of  the  sldn  is  the  result  of  an  exter- 
nal or  an  internal  cause  is  the  first  stei)  in  the  treatment  of  erythema.  "When  it  results  from 
the  pressure  of  a  truss,  a  splint,  or  other  orthopaedic  apparatus  {E.  traumaticum)  the  inter- 
position of  canton  flannel  or  absorbent  cotton  between  the  hard  substance  and  the  skin  may 
prevent  the  occurrence  of  eczema  or  ulceration  from  the  pressure  exerted.  The  erythema 
I'esulting  from  the  action  of  heat  or  cold  {E.  calorieum)  speedily  disappears  with  the  cessa- 
tion of  the  cause.  Redness  and  irritation  of  the  skin  is  sometimes  produced  by  wearing  new 
stockings  and  undergarments  containing  aniline  dyes  {E.  venenatum).  To  relieve  this  a 
change  in  the  character  of  the  clothing  is  often  necessary. 

For  sympathetic  erj^hema,  which  is  often  persistent  and  sometimes  associated  \vith  a 
slight  burning  sensation,  a  removal  of  the  cause  is  of  the  first  importance.  For  the  flushing 
of  the  face,  which  is  apt  to  occur  in  women  at  the  time  of  the  menopause,  the  inhalation  of 
amyl  nitrate  and  the  administration  of  mild  doses  of  belladonna  have  been  found  useful. 
Locally,  a  dusting  powder,  will  commonly  act  as  a  placebo,  and  a  lotion  of  lead  and  opium,  if 
called  for  by  an  annoying  sensation  of  heat  in  the  part  affected,  will  prove  of  benefit. 

Erytiiejia  exfoliativum.  In  rare  instances  erythema  may  invade  the  whole  surface  of 
the  skin  and  cause  a  general  desquamation.  The  attacks  may  recur  at  intervals,  and  any  one 
of  them  might  be  hastily  mistaken  for  scarlet  fever.  The  follo^ving  case  will  serve  :is  an 
illustration  of  this  peculi?  r  form  of  the  affection  : — 

Chas.  O.,  eet.  23,  Gennan.— By  occupation,  a  porter.— The  patient  had  a  sallow  com- 
plexion, but  was  strong  and  apparently  iu  good  condition.  He  gave  the  following  history  : 
In  his  youth,  from  the  age  of  four  to  fourteen,  he  had  suffered  every  summer  from  a  general 
"peeling  of  the  skin."  The  attack  would  usually  confine  him  to  his  bed  for  five  or  six 
weeks,  and  he  remembers  that  large  sheets  of  skin  could  be  removed  entire  from  his  body.

DISEASES  OF  TEE  SKIN.—INFLAMMATOR  Y. 

At  the  close  of  each  attack,  the  thick  skin  of  the  soles  of  the  feet  would  separate  in  two 
portions,  one  from  the  ball  of  the  foot  and.  one  from  the  heel.  His  four  brothers  and  one 
sister  were  all  healthy,  as  was  the  patient  himself,  between  these  annual  attacks.  From  the 
age  of  fourteen  to  twenty-two  he  was  in  good  health,  and  free  from  his  early  trouble,  with 
the  exception  of  a  single  mild  attack,  which  occurred  when  about  nineteen.  Dui-ing  the  past 
six  months  he  had  at  least  six  mild  attacks,  in  such  rapid  succession  that  the  erythema  would 
sometimes  appear  upon  the  body  before  the  palms  had  finished  scaling  as  the  result  of  a 
former  attack.  When  first  seen  by  me  (January  20),  the  patient  stated  that  on  the  morning 
of  the  previous  day  he  had  awoke  to  find  his  body  and  extremities  reddened,  as  was  usual  at 
the  beginning  of  an  attack.  An  examination  revealed  a  vivid  erythema  upon  the  sides  of 
the  trunk,  the  neck,  arms,  and  thighs.  The  skin  on  the  palms  was  dry  and  harsh,  and  ap- 
parently beginning  to  separate.  (This  condition  resulted  from  a  preA'ious  attack,  which 
occurred  a  few  weeks  before).  It  began  to  exfoliate  shortly  after,  and  jjresented  the  appear- 
ance often  seen  after  scarlatina.  The  erji:hema  quickly  became  universal,  ^dth  the  exception 
of  the  face,  penis,  and  back  of  hands,  and  was  immediately  followed  by  a  desquamation  of 
the  epidermis.  On  the  scalp  it  occasioned  an  acute  attack  of  pityiiasis.  On  January  26th 
the  attack  was  waning ;  it  had  been  severer  than  his  recent  attacks,  but  did  not  compare  in 
severity  with  those  which  he  had  as  a  boy.  The  sldn  of  the  body  appeared  of  a  dusky  red 
hue.  indicati'/e  of  venous  congestion.  The  skin  on  the  inner  side  of  the  thighs  and  gluteal 
region  v  as  qidte  dark,  and  on  close  examination  presented  a  slightly  powdery  surface. 
Dra.virig  the  finger  nail  rapidly  over  it  a  number  of  times  produced  at  first  whitish,  chalky 
lines,  v.-hich  rapidly  assumed  a  bright  red  color,  contrasting  strongly  with  the  surrounding 
livid  hue.  There  was  no  evidence  of  urticaria,  and  this  initation  of  the  skin  was  unaccom- 
panied by  itching.  The  knees  appeared  whitish  from  the  presence  of  thin,  adherent  scales, 
and  there  was  a  certain  amount  of  pityriasis  on  various  portions  of  the  body. 

On  March  2nd,  patient  came  to  me  with  another  attack.  Two  days  before  he  had  felt  per- 
fectly well.  He  slept  well  that  night,  but  awoke  on  the  following  morning  with  the  redness 
of  the  whole  body,  excluding  head,  hands  and  feet.  The  skin  was  hot  as  well  as  red,  and  he 
experienced  a  bui-ning  sensation,  especially  at  the  flexures  of  the  joints.  He  felt  weak 
during  the  day,  and  complained  of  nausea,  but  again  slept  ^vell.  When  seen  by  me  the 
brightness  of  the  erythema  was  akeady  fading,  and  the  skin  appeared  like  that  of  an  Indian, 
or  as  it  sometimes  appears  after  staining  with  chrysophanic  acid.  His  red  flannel  under- 
clothing, which  had  lost  its  brightness  by  long  use,  very  nearly  matched  the  shade  of  the 
skin.  The  hyperemia  was  intense,  but  of  a  passive  character,  and  the  body  contrasted 
strongly  with  the  face,  which  was  pale  and  sallow.  On  ]\Iarch  5th  the  pui-plish  redness  had 
faded,  and  where  the  skin  was  naturally  thin,  the  desquamation  was  beginning  at  numerous 
points,  in  the  form  of  smaU  siliquose  elevations  of  the  epidermis.  From  these  points  the 
desquamation  proceeded  centrifugaUy,  leaving  patches  of  normal  skin,  surrounded  by  an 
irregular  white  line  of  exfoliating  epidermis.  On  March  7th  there  were  islands,  not  of  denuded 
skin,  as  before,  but  of  old  epidemiis.    These  remaining  patches  appeared  of  a  dirty  yellowish- 

(32) 


ERYTHEMA   INTERTRIGO. 

brown  color,  and  were  dotted  by  the  siliquose  elevations  of  epidermis,  and  small  circular 
spots,  from  wMch  the  epidermis  had  fallen.     The  patient  was  feeling  perfectly  well. 

ERYTHEMA  INTERTRIG-O. 

A  simple  erythema  is  freqiiently  produced  by  the  contact  and  friction  of  two  opposing 
surfaces  of  skin.  When,  in  such  cases,  heat  and  moisture  are  present  to  an  unusual  degi'ee, 
a  maceration  of  the  epidermis  and  the  production  of  a  raw  surface  frequently  takes  place  and 
gives  use  to  that  condition  which  is  usually  designated  by  the  term  "intertrigo."  The  affec- 
tion is  very  common  in  infancy,  when  the  skin  is  delicate.  It  also  occurs  in  adult  life,  espe- 
cially among  the  corjjulent.  The  genital  region  and  the  gluteal  furrow  is  its  most  common 
site,  but  in  very  fat  infants  it  is  also  observed  in  the  folds  of  the  neck  and  in  the  flexures  of 
the  joints.  In  women  with  large  pendulous  breasts,  and  especially  among  those  who  are 
nursing  infants,  it  is  very  common.  In  short,  it  is  liable  to  occur  wherever  two  surfaces  of 
skin  are  in  close  apposition  and  inclined  to  rub  against  each  other. 

In  hot  weather  the  affection  is  always  aggravated,  but  it  is  by  no  means  confined  to  this 
season  of  the  year.  It  usually  develops  suddenly,  or  at  least  increases  rapidly  in  severity 
as  soon  as  the  parts  begin  to  appear  chafed.  The  natural  heat  and  moisture  of  the  opposing 
surfaces  induce  congestion  of  the  skin,  and  this  naturally  increases  the  amount  of  heat  and 
stimulates  the  persph-atory  glands  to  excessive  action.  The  skin  now  becomes  deeply  red- 
dened, bathed  in  a  serous  discharge,  which  emits  a  very  disagi-eeable  odor,  and  in  the  deep- 
est portion  of  the  sldn  a  painful  fissure  is  very  apt  to  form.  In  infants  whose  urine  or  foecal 
discharges  are  allowed  to  remain  in  contact  with  the  sldn,  a  raw  or  even  an  ulcerated  surface 
may  be  produced,  and  this  is  more  especially  apt  to  be  the  case  if  the  mine  is  very  acid,  or  the 
discharge  from  the  bowels  is  loose  and  acrid  in  character.  The  affection  may  be  slight,  and 
disappear  spontaneously  in  a  few  days,  but  generally  it  tends  to  become  aggi-avated,  espe- 
cially in  the  case  of  infants,  and  often  persists  for  months  or  until  the  most  careful  treatment 
is  instituted. 

Diagnosis.  The  intertrigo  of  infants  is  readily  recognized  as  such,  but  in  certain  cases 
where  a  tendency  to  eczema  exists,  the  skin  becomes  gradually  thickened  and  tends  to  remain 
red  and  scaly  after  the  moisture  of  the  parts  has  disappeared.  Just  at  what  period  the  inter- 
trigo may  be  considered  as  having  become  transformed  into  an  eczema  is  not  always  easy  to 
determine.  The  redness  and  moisture  are  symptoms  common  to  the  two  affections,  but  the 
Infiltration  of  the  skin  is  not  met  ^vith  in  piu-e  intertrigo,  and  when  present  must  be  consid- 
ered as  indicative  of  eczema. 

Treatment.  The  successful  treatment  of  intertrigo  is  by  no  means  as  easy  a  matter  as 
one  with  little  experience  might  at  first  imagine.  The  indications  are- to  keep  the  parts  clean 
and  dry  and  the  qjji)osing  surfaces  separated  for  a  time  by  the  interposition  of  some  unirrita- 
ting  substance,  be  it  linen,  cotton,  powder  or  salve.  In  infants  these  indications  are  not 
always  easy  to  fulfil.      It  is  difficult  to  impress  upon  the  mind  of  some  mothers  and  nurses 

(33) 


DISEASES  OF  THE  SK/y.-EYFLAMMATOBY. 

the  great  importance  of  removing  the  napkins  immediately  after  the  passage  of  urine  or 
evacuation  of  the  bowels.  A  few  minutes'  contact  of  the  uriue  or  f ceces  with  the  tender  and 
inflamed  skin  will  often  destroy  the  good  results  of  the  most  careful  treatment.  When  the 
skin  is  but  slightly  inflamed,  the  parts  may  be  occasionally  washed  with  castile  soap  and 
water,  but  when  there  are  abmded  surfaces  this  plan  of  treatment  is  apt  to  aggravate  the 
ti'ouble,  and  especially  where  thei-e  is  a  tendency  to  eczema,  water  should  be  proscribed.  A 
dusting  powder  of  the  blandest  character  is  usually  of  the  greatest  service  in  the  treatment  of 
these  cases,  and  should  be  freely  applied  to  the  surface.  Where  there  is  but  slight  moisture 
lycopodium  is  doubtless  the  best  application,  but  when  a  powder  of  an  absorbent  character 
is  needed,  com  starch  may  be  used  in  preference  to  the  ordinary  starch  powder,  as  it  is  less 
gritty,  or  what  is  perhaps  still  better,  prepared  chalk  or  fullers'  earth.  "When  there  are  raw 
surfaces,  a  powder  prepared  by  saturating  French  chalk  or  talc  with  the  tincture  of  calen- 
dula, and  slowly  drying  the  same,  may  be  applied  with  excellent  results,  the  parts  being 
separated  by  the  intei-position  of  a  piece  of  soft  linen  cloth  slightly  greased  mth  mutton 
tallow  to  prevent  its  adherence. 

For  the  intertrigo  of  adults  a  similar  plan  of  treatment  may  be  adopted,  but  in  all  cases 
the  physician  must  see  that  his  directions  are  thoroughly  carried  out  or  success  will  be  unat- 
tainable, and  even  when  the  cure  is  apparently  accomplished,  the  possibility  of  a  relapse  must 
be  guarded  against. 


ERYTHEMA   MULTIFORME- 

Tlie  term  erythema  indicates  a  pathological  congestion  of  the  skin.  When  hjqiersemic 
redness  is  the  sole  lesidn  in  any  case,  the  affection  is  erythema  simplex.  When  the  conges- 
tion of  tlie  skin  is  accompanied  by  a  peculiar  jilastic  exudation,  we  have  an  entirely  different 
affection,  and  one  to  which  Hebra  applied  the  distinctive  title  of  erythema  exsudativum  mul 
tiforme.  Although  the  generic  term  erythema,  adopted  by  Willan  in  his  lesional  classiflca 
tion,  is  still  in  use,  the  reader  must  bear  in  mind  that  erythema  simplex  and  erythema  m,ul 
tiforme  are  not  mere  varieties  of  one  cutaneous  disease,  but  that  they  are  quite  independeni 
affections,  according  to  a  classification  based  on  etiology  or  pathology. 

Erji;henia  multifonne  is  an  acute  inflammatory  affection,  characterized  by  a  marked  de- 
gree of  supei-ficial  plastic  exudation.  This  leads  to  the  rapid  development  of  either  paijules, 
tubercles,  elevated  rings  or  diffused  marginate  patches.  In  exceptional  cases,  vesicles  and 
bullfc  develop  upon  the  sui'face  of  these  lesions.  The  varying  character  of  the  eruption  lias 
led  to  the  establishment  of  a  number  of  clinical  forms  which  ditl'ei-  from  one  another  in  exter- 
nal appearance.  Chief  among  these  may  be  considered  three  types  of  the  affection,  which 
are  known  as  Erythema  j)fipul<xtum,  Erj^hema  hullosum,  and  Erythema  nodosum. 

ERYTHEMA  PAPULATUM.  This  is  the  most  common  fonn  of  Erythema  multiforme 
and  occurs  chiefly  on  the  backs  of  the  hands  and  foreamis.  In  some  cases  it  appears  on  the  feet 
and  legs  as  well.     The  lower  extremities  are  rarely  affected  alone.     In  E.  tuberculatum  the

papules  are  simply  larger  and  firmer.  They  present  at  times  a  whitish  summit  and  appear 
like  buUfe  containing  gelatinous  contents.  In  a  case  which  I  recently  saw,  the  tubercles  on 
the  backs  of  the  fingers  were  dark  and  purpuric  in  character.  In  E.  annulatum  a  large  flat 
papule  or  disk  of  exudation  presents  a  depressed  central  areti,  and  in  rare  instances,  one  or 
more  outer  circles  form,  and  by  exhibiting  a  variation  in  color  give  rise  to  the  name  E. 
iris.  E.  marginatum  is  applied  to  the  eruption  when  it  appears  in  the  foi-m  of  diffused 
patches  with  an  abrupt  and  elevated  border  which  is  usually  scalloped  from  the  coalition  of 
smaller  circular  patches. 

The  following  case  will  illustrate  the  features  of  the  annular  form  of  erythema  : — W.  R.., 
set.  34,  American. — By  occupation,  a  pilot. — This  patient  was  sent  by  Dr.  Robert  Abbe  to  a 
meeting  of  the  New  York  Dermatological  Society,  and  afterward  kindly  placed  under  my 
observation.  He  was  a  large  and  powerful  man,  apparently  in  perfect  health.  A  searching 
examination  made  by  Dr.  Abbe  failed  to  reveal  any  history  or  evidence  of  syphilis.  He  had 
never  had  any  eruption  elsewhere  upon  the  skin,  and  with  the  exception  of  a  slight  attack  of 
rheumatism,  had  never  been  iU.  His  tongue  was  clean,  his  appetite  good,  his  bowels  slightly 
constipated,  and  his  urine  clear.  He  stated  that,  six  weeks  previously,  a  small,  itchy  red 
spot  appeared  in  the  centre  of  his  left  palm,  and  gradually  increased  in  size.  A  few  days 
later  two  similar  spots  appeared  in  right  palm.  About  six  months  before  this,  the  patient 
had  suffered  from  a  similar,  though  milder  attack.  There  were,  at  that  time,  two  or  three 
circular,  non-elevated  patches  in  each  palm,  which  itched  exceedingly,  and  disappeared  in 
about  a  month  without  treatment.  No  scaling  followed.  Upon  examination  of  the  palms 
during  the  second  attack,  the  centre  of  each  was  found  to  be  the  seat  of  a  nearly  circular, 
purplish-red  ring.  The  circle  in  the  left  palm  (see  illustration  in  first  edition),  pre- 
sented an  irregular  border,  and  appeared  as  though  one  or  two  small  rings  had  coalesced 
with  the  central  circle  by  centrifugal  extension.  On  the  right  palm  were  three  small  lesions, 
in  addition  to  the  central  circle,  two  being  near  the  latter,  and  one  on  the  long  linger,  near 
its  base.  The  e  small  lesions  were  just  beginning  to  grow  annular  by  a  fading  of  the  color 
in  the  centre.  The  central  circles  were  of  hali  dollar  size,  and  not  at  all  elevated,  although 
Dr.  Abbe  assures  me  that  they  were  so  at  the  outset.  Their  most  striking  feature  consisted 
in  a  double  border,  the  inner  one  being  of  a  purplish-red  color,  and  evidently  indicating  th( 
height  of  the  exudative  process,  the  outer  one  appearing  whitish,  like  the  epidermis  raised 
by  a  blister.  The  lesions  were  not  very  striking  in  appearance,  especially  the  incipient  ones. 
But  the  purple  band  of  the  central  circles  showed  very  plainly  when  the  lingers  were  forcibly 
extended,  so  as  to  blanch  the  surrounding  tissue,  or  when  the  palm  was  rubbed  briskly  for  a 
few  seconds  with  the  corner  of  a  dampened  towel.  The  eruption  was  accompanied  by  a  severe 
and  annoying  itching,  which  kept  the  patient  rubbing  or  picking  at  the  palms,  but  the  epi- 
dermis was  not  at  all  excoriated. 

The  treatment  adopted  at  first,  in  this  case,  was  purely  expectant,  but  as  the  eruption 
showed  no  tendency  to  disappear  of  its  own  accord,  as  it  had  done  six  months  before,  the 
patient  was  ordered  nightly  frictions  with  green  soap,  to  be  followed  by  the  uiuufjlon  of

mercurial  oiaiiiient.  This  appeared  to  have  no  effect,  and  on  January  6,  two  weeks  after  the 
photognii^h  was  taken,  the  rings  were  increasing  in  size,  and  very  itchy,  especially  after  wash- 
ing the  hands.  Rochelle  salts  internally  and  chrysophanic  acid  ointment  locally  were  ordered, 
and  the  eruption  disappeared  after  a  duration  of  ten  weeks. 

In  the  beginning,  the  eruption  of  Erythema  multiforme,  whether  papular,  annular  or 
marginate,  is  seated  upon  a  slightly  swollen  and  reddened  base.  "Within  twenty-four  hours 
the  encircling  hypereemia  subsides,  and  leaves  the  eruption  contrasting  strongly  with  the 
normal  skin.  The  color  changes  gradually  from  a  bright  red  to  a  dull,  livid  or  purplish  hue, 
and  the  affection  runs  its  course  in  from  one  to  six  weeks,  according  to  the  intensity  of  the 
exudative  process.  An  average  case  will  last  from  two  to  three  weeks.  Frequently  the 
lesions  develop  successively,  aiad  the  attack  is  thereby  prolonged.  Recurrent  attacks  at  cer- 
tain seasons  of  the  year  are  not  tmcommon.  The  outbreak  of  the  eruption  is  often  associated 
with  malaise  and  slight  fever,  and  according  to  my  experience,  the  eruption  is  usually  quite 
annojdng  on  account  of  the  burning  sensation  or  pruritus,  which  is  nearly  always  present. 
Most  writers,  however,  speak  of  the  subjective  symptoms  as  being  insignificant. 

The  causes  of  erythema  papulatum  are  rarely  apparent.  It  is  frequently  met  witli  in  the 
spripg  and  autumn,  and  the  sudden  changes  of  temperature  so  common  in  this  climate  seem 
to  me  to  be  an  etiological  factor  of  importance.  In  dispensary  practice  I  have  had  occasion 
to  note  that  immigrants  are  a  class  peculiarly  liable  to  be  affected.  In  many  cases  a  lowered 
tone  of  the  system  is  evident,  but  the  disease  does  not  seem,  like  urticaria,  to  be  attributable 
to  dietetic  en-ors.  It  is  generally  met  with  in  youth  and  middle  age,  and  neither  sex  is  ex- 
empt. 

DiACrifosis.  Erythema  papulatum  occurring  in  a  well  marked  and  typical  form  is  easily 
recognized  by  any  one  at  all  familiar  mth  the  clinical  appearance  of  the  affection.  In  many 
cases,  however,  it  might  be  readily  compounded  with  urticaria,  eczema  or  syphilis.  From 
urticaria,  to  which  it  is  closely  allied  in  its  pathological  nature,  it  may  be  distinguished  by 
the  persistence  of  its  lesions  and  by  the  subjective  sensation,  which  is  one  of  burning  rather 
than  itching.  The  papules  or  patches  are  never  white  like  the  wheals  of  urticaria,  nor  do 
they  ever  appear  and  vanish  as  suddenly.  "When  eczema  occurs  in  small  imperfectly  de- 
veloped patches  upon  the  backs  of  the  hands,  and  on  the  forearms,  a  difficulty  in  diagnosis 
might  arise  at  the  outset.  But  the  speedy  appearance  of  a  tendency  to  moisture,  or  the  in- 
evitable formation  of  scales  would  greatly  lessen  the  resemblance,  inasmuch  as  the  lesions  of 
papular  erythema  never  present  an  exuding  surface,  nor  become  scaly.  They  always  possess 
nioreover  an  abrupt  margin  which  is  very  rarely  met  with  even  in  small  jjatches  of  eczama. 

Tkkatmext.  The  treatment  of  the  affection  may  be  expectant  or  consist  in  good  nurs- 
iag.  Warm  baths  are  beneficial.  A  teacupful  of  carbonate  of  sodiiun  may  be  added  to  the 
Mater  ^^hen  the  eruption  is  extensive  and  accompanied  by  pruritus.  A  linen  cloth  saturated 
A-ith  a  lead  lotion  may  be  applied  to  the  affected  skin  at  the  outset,  when  the  inflammatory 
symptoms  are  very  acute.     Later  a  dusting  powder  may  be  prescribed  with  a  view  to  divert-

ERYTHEMA  BULLOSUM.  Hydroa,  a  term  first  employed  by  Bazin,  has  gradually 
come  into  use  during  the  past  twenty  years.  It  is  generally  applied  to  certain  cases 
of  vesicular  or  vesiculo-  bullous  eruption  occurring  upon  an  erythematous  base  and  pos- 
sessing clinical  features  which  serve  to  distinguish  them  from  herpes  and  from  pemphi- 
gus, with  which  afi'ections  they  were  formerly  confounded.  The  disease  is  not  a  common 
one,  and  while  the  cases  met  with  present  salient  features  which  mark  their  identity,  they 
vary  in  their  clinical  aspect  to  such  an  extent  that  a  concise  definition  cannot  be  given  which 
will  include  all  forms  of  the  affection.  For  the  most  part  they  present  the  features  of  multi- 
form erythema  with  the  vesicular  or  bullous  development  super-added.  The  term  erythema 
bullosum  is  therefore  preferable  to  the  term  Hydroa,  which  does  not  suggest  the  fact  that 
the  affection  is  but  a  phase  of  erythema  multiforme.  The  leading  characteristics  of  erythema 
bullosum  are  its  symmetrical  distribution,  its  peculiar  locality,  its  tendency  to  recur  at  longer 
or  shorter  intervals,  and  the  constitutional  derangement  which  usually  accompanies  the  erup 
tion.  It  begins,  as  a  rule,  by  the  sudden  development  of  erythematous  papules  or  patches, 
upon  the  central  portion  of  which  a  single  vesicle  or  group  of  vesicles  is  rapidly  f  onned.  These 
are  usually  of  large  size  and  hemispherical.  They  contain  at  first  clear  seram,  which  in  a  few 
days  becomes  cloudy  and  gives  to  the  patches  a  whitish  or  even  a  yellowish  aspect.  There 
are  generally  some  isolated  vesicles  or  bullae,  and  these  do  not  always  spring  from  an  erjrthe- 
matous  base.  They  may  attain  the  size  of  pemphigus  bullae,  and  become  surrounded  as  they 
mature,  by  a  narrow  zone  of  infiammation.  The  groups  of  vesicles  tend  to  become  depressed 
in  the  centre,  and  sometimes  an  advancing  vesicular  margin  is  noted.  A  tendency  to  succes- 
sive crops  of  vesicles  is  common,  and  when  the  eruption  is  subsiding  at  one  point,  a  relapse 
may  take  place  upon  some  other  portion  of  the  body. 

The  serous  contents  of  the  vesicles  and  bullae  tend  to  become  absorbed  and  leave  merely 
a  desquamating  epidermis,  but  when  the  lesions  are  ruptured  by  scratching  or  other  external 
violence,  a  yellowish  crust  or  a  dark  scab  may  form.  The  subjective  symptoms,  in  a  mild 
case,  consist  chiefly  in  a  burning  sensation,  but  in  many  cases,  and  especially  in  those  which 
run  a  more  chronic  course,  the  itching  may  be  intense.  There  is  generally  a  mai-ked  impair- 
ment of  the  general  health  preceding  the  attack,  and  while  the  eruption  is  present,  the  patient 
is  usually  wholly  unfitted  for  his  customary  duties.  There  occur  now  and  then  rheumatic  com- 
plications, and  effusion  into  the  knee  joint  has  been  reported.  The  disease  commonly  runs  an 
acute  course,  the  successive  crops  of  vesicles  disappearing  in  a  few  weeks  or  months,  but  it 
may  persist  for  years.  It  is  non-contagious,  and  though  in  many  instances  a  severe  affection, 
it  is  rarely,  if  ever,  fatal.

VISEASES  OF  THE  SKTX.— INFLAMMATORY. 


The  favorite  seat  of  erythema  bullosum  is  upon  the  extensor  surface  of  the  forearms  and 
hands,  the  face  and  ears,  the  genitals,  knees  and  feet.  In  many  cases  the  oral  cavity  is  like- 
•wise  affected,  the  uviila  and  soft  palate  being  frequently  the  seat  of  vesicles,  or  presenting  an 
inflamed  or  eroded  appearance.  The  affection  is  apt  to  attack  young  persons,  and  appears  to 
be  most  common  in  the  early  mnter  and  early  summer.  Some  may  have  a  number  of  attacks 
during  the  year,  and  cases  have  been  reported  where  an  annual  attack  has  occurred  since 
childhood.  The  causes  of  the  affection  are  obscure,  but  it  is  evident  that  the  eruption  is 
due  to  derangement  of  nerve-centres,  and  not  dependent  upon  any  blood  changes. 

The  diagnosis  is  not  difficult,  but  as  there  are  no  sharp  boimdary  lines  between  herpes, 
erythema  bullosum,  and  pemphigus,  cases  often  occur  which  illustrate  the  relationship  of  the 
three  affections  named,  and  a  question  might  arise  as  to  the  most  appropriate  term  for  a 
given  case.     The  main  features  of  the  three  affections  may  be  contrasted  as  follows : — 


Lesion. 
Location. 

Course. 
Treatme. 


Hekpes. 

Vesicles  in 
groups. 

Face  and  genitals 
only. 

Acute,  lasting  but 
a  few  days. 

None  required. 


Erythema  bullosum. 

Large  vesicles  or  bullse 
isolated  or  grouped. 

Face,  forearms,  scrotum, 
knees  and  feet.  Rarely 
general. 

Acute  or  chronic,  lasting 
a  few  weeks  or  longer. 

Treatment  may  hasten 
the  cure. 


Pemphigus. 

Bullse,  always  iso- 
lated. 

All      portions     ol 
the  body. 


Chronic,       lasting 
for  years. 

Is    rarely    cui-ed, 
and  often  fatal. 


The  chief  aim  of  treatment  in  a  case  of  erythema  bullosum  should  be  to  restore  to  the 
patient  his  natui-al  degree  of  health  of  mind  and  body,  talving  little  account  in  most  cases  ol 
the  eruption  upon  the  skin.  The  nervine  tonics,  such  as  arsenic,  quinine,  and  cod-liver  oil, 
are  highly  recommended,  and  ^^'ith  these,  and  the  beneficial  effects  of  a  complete  cessation 
from  work  and  wony,  with  perhaps  a  change  of  scene  when  it  is  practicable,  a  speedy  cure 
may  be  expected.  When  the  patches  aie  in  a  highly  inflammatory  condition,  the  common 
lead  and  opium  wash  is  of  sei-vice,  and  when  itching  is  a  prominent  symptom,  the  parts  may 
be  rubbed  with  camphoiuted  oil. 

ERYTHEMA  NODOSUM.  This  is  described  by  some  as  distinct  from  erythem;.  multi- 
forme, but  its  nature  is  thj  same  however  different  may  be  its  appeai-ance.  Although  it 
is  almo'it  always  met  with  alone,  it  may  co-exist  with  the  papular  or  marginate  forms.  It 
is  usually  met  with  upon  the  extensor  aspect  of  the  legs  and  arms,  and  is  characterized  by 
'  liH  ai)peai'ance  of  one  or  more  painful  swellings,  varying  in  size  from  an  almond  to  a  small  egg. 
These  appear  usual!}'  in  connection  with  marked  general  malaise,  and  more  or  less  fever,

lesions  will  prolong  the  disease.  The  nodose  swellings  reach  their  height  in  two  or  three 
days,  and  at  this  time  present  a  peculiar  bluish  red  appearance,  somewhat  resembling  a 
recent  contusion. 

The  border  is  never  abrupt  and  the  color  gi-adually  shades  off  into  tlie  surrounding  skin. 
The  subjective  sensation  is  of  a  burning  pain,  the  affected  skin  is  exquisitely  tender,  and 
when  the  lesions  are  numerous  upon  the  shins  the  patient  becomes  scarcely  able  to  walk. 
The  tumors  may  remain  in  this  condition  i'or  two  or  three  days,  when  the  tension  of  the 
skin  lessens,  the  swelling  subsides  slightly,  the  color  becomes  duller  and  sometimes  passes 
through  the  variegeted  changes  which  are  noticed  after  a  bruise.  Children  and  young  women 
are  most  apt  to  suffer  fi'om  the  affection,  and  more  especially  those  who  are  weakly  and  iU 
nourished. 

Diagnosis.  WTien  the  affection  occurs,  as  it  does  in  the  vast  majority  of  cases,  over  the 
shins,  it  might  be  mistaken  at  first  sight  for  a  number  of  contusions.  But  the  absence  of 
any  history  of  external  violence,  together  with  the  marked  constitutional  disturbance,  will 
serve  to  exclude  such  :i  diagnosis.  Abscesses,  boUs  and  the  gummy  tumors  of  sj^phOis  bear  a 
slight  resemblance  to  the  lesions  of  erythema  nodosum,  but  the  latter  are  too  highly  colored 
for  incipient  abscesses,  too  large  as  a  rule  for  furuncles,  and  too  acute  in  theu-  course  foi 
gummy  tumors.  WTien  the  lesions  occur,  as  they  may  do,  upon  the  face  or  body,  the  diag- 
nosis is  more  difficult  and  can  only  be  made  after  a  most  careful  study  of  the  case. 

Teeatment.  As  the  disease  runs  its  course  and  terminates  spontaneously  if  left  to  itself^ 
our  chief  aim  in  treatment  is  to  ease  the  suffering  of  the  patient,  which  is  usually  considera- 
ble. It  is  probable  also  that  judicious  treatment  will  shorten  its  natural  course.  Rest  in 
bed,  ^^'ith  hot  applications  to  the  painful  tumors,  is  of  the  first  importance.  Aconite  may  be 
administered  in  small  doses  at  the  outset  and  followed  by  iron  and  mineral  acids.  Locally, 
Piffard  recommends  the  application  of  hamamelis  and  arnica,  which  may  be  employed  to 
advantage  in  connection  with  the  hot  compresses.  Finally,  when  the  tenderness  of  the 
lesions  upon  the  legs  has  subsided,  the  finn  pressure  of  a  smoothly  applied  flannel  bandage 
w'ill  hasten  a  cure. 

.     URTICAIIIA. 

{Synonym — Nettle  Hash,     Hives.) 

Urticaria  is  an  affection  of  the  skin,  in  which  certain  peculiar  lesions  called  "wheals" 
appear  suddenly  'uith  or  without  apparent  cause,  and  after  a  brief  dvu-ation  of  a  few  hours 
disappear  almost  as  si.ddenly  as  they  came.  A  single  outbreak  of  these  wheals  may  consti- 
tute the  whole  of  the  uttack.  but  generally  they  appear  as  successive  crops,  and  thus  the  affec- 
tion assumes  a  chronic  form.  The  wheals  are  solid  inflammatory  elevations  of  the  skin  of  a 
perfectly  white  or  pinkish  hue,  with  an  abrupt  margin  and  a  bright  red  hj^per^mic  halo. 
They  are  commonly  circular  or  oval  in  shape  and  vary  greatly  in  size.  In  a  mild  case  they 
are  no  larger  than  the  tip  of  the  finger,  but  in  a  severe  acute  outbreak  they  may  occur  in

piitches  'A  iiTegiilar  fonn,  and  cover  portions  of  the  body  as  large  as  the  palm  of  the  hand. 
In  certain  cases  the  whole  trunk  wU  be  covered  either  by  the  wheals  themselves  or  by  the 
active  h\-perjBmia  which  surrounds  them.  Occasionally  the  wheals  arp  linear  in  fonn,  espe- 
cially when  induced  by  the  pressure  or  friction  of  the  clothing.  Though  commonly  raised  no 
more  than  an  eighth  of  an  inch  above  the  level  of  the  skin,  in  rare  instances  they  fonn 
tumors  ad  large  as  an  English  walnut  (giant  urticaria). 

Acccmpanying  the  lesions  there  is  always  a  bui-ning  or  stinging  sensation,  which  is 
extremel  r  annoying,  and  frequently  there  is  such  an  intense  pruritus  that  fierce  scratching 
and  exec  nation  of  the  skin  is  inevitable.  During  an  attack  the  skin  over  the  greater  portion 
of  the  body  is  abnormally  irritable,  and  the  scratching  only  serves  to  increase  the  number  of 
wheah.  The  affection  occurs  at  aU  ages,  but  the  acute  form  is  more  common  in  childhood. 
The  eruption  may  exist  alone  or  in  connection  va(h.  some  other  disease  of  the  skin. 

Etiology.  There  is  no  affection  of  the  skin  \vhich  may  result  from  so  many  distinct 
causes  as  urticaria,  and  as  success  in  its  treatment  depends  largely  upon  the  discovery  of  the 
cause,  an  acquaintance  with  its  various  etiological  factors  is  of  the  highest  importance.  The 
eruption,  or  at  least  the  peculiar  u'ritability  of  the  .skin  which  precedes  and  favors  the  erup- 
tion is  always  the  result  of  reflex  nervous  irritation,  and  the  exciting  cause  may  act  either 
within  or  without  the  body. 

The  external  causes  of  the  eruption  may  be  of  a  vegetable,  animal,  mechanical  or 
meteorological  nature.  The  contact  of  the  skin  with  certain  species  of  Urtica  or  stinging 
nettle  is  the  most  evident  of  all  the  external  causes  of  urticaria  or  nettle-rash,  and  the  one 
which  has  given  to  the  disease  both  its  scientific  and  its  poptilar  name.  The  stinging  power 
which  the  nettle  exerts  is  supposed  to  reside  in  minute  tubular  hairs  or  prickles,  which  transmit 
a  venomous  fluid  when  pressed.  It  is  well  known  that  the  bites  of  mosqtiitos,  bedbugs,  lice, 
and  ileas  often  evoke  urticarial  wheals,  not  only  at  the  seat  of  attack  but  upon  other  portions 
of  the  body.  In  the  case  of  the  two  latter  pests  the  exciting  cause  of  the  eruption  is  not 
infrequently  overlooked.  The  eruption  may  result  also  from  contact  with  the  slimy  secretion 
of  the  jelly-fish,  and  with  certain  hairy  caterpillars  of  the  genus  Bombyx.  Upon  a  healthy  skin 
a  linear  wheal  or  welt  can  readily  be  prodticed  by  giving  the  skin  a  sharp  cut  with  a  switch. 
Upon  the  skin  of  certain  susceptible  persons  a  somewhat  similar  lesion  may  be  produced  by 
the  pressure  or  friction  of  clothing  or  mechanical  imtation  of  any  sort.  Letters  traced  upon 
the  skin  ^\•ith  the  finger-nail,  or  any  pointed  instrument,  will  appear  in  white  relief  ttpon  a 
pink  background  in  the  course  of  a  minute  or  two  (  U.  factitia).  The  application  of  leeches, 
and  the  puncture  of  echino-coccus  cysts  have  repeatedly  been  followed  by  the  development  of 
urticaria.  The  disease  sometimes  coexists  or  alternates  with  asthma,  in  which  case  it  is  very 
apt  to  be  induced  by  exposure  to  cold  air. 

The  internal  causes  of  urticaria  are  even  more  numerous  than  the  external,  although  less 
susceptible  of  demonstration.  They  may  be  classified  as  dietary,  medicinal,  emotional  or 
morbid  in  character,  and  the  resulting  eruption  must  be  regarded  as  a  purely  symptomatic 
one.  Urticaria  from  the  use  of  certain  articles  of  food  usually  appears  in  an  acute  form,  with 
or  without  fever.     In  some  instances  the  eruption  appears  with  a  marvellous  suddenness,  even

before  the  offending  substance  has  been  fairly  swaDowed,  and  from  this  it  would  seem  pit)ba- 
ble  that  the  peculiar  irritation  of  the  nei-ves  of  taste  is  reflected  immediately  to  the  skin,  and 
that  the  eruption  is  not  due  to  the  absorption  of  the  substance  and  its  circulation  through  the 
blood.  The  articles  of  food  which  have  been  observed  to  produce  this  singular  effect  upon 
the  sldn  in  the  case  of  certain  individuals  are  eaten  by  others  with  perfect  impunity.  The 
list  of  such  articles  is  an  extensive  one  and  comprises  fish,  clams,  oysters,  lobsters,  crabs, 
pork,  eggs,  honey,  mushrooms,  cucumbers,  berries,  fruit,  etc.  Various  drugs,  when  taken 
internally,  are  liable  to  provoke  an  exanthematous  eruption  (Dermatitis  medicamentosa) 
which  is  ofteji  of  an  urticarial  character.  Quinine,  cinchonidia,  salicylic  acid,  belladonna, 
valerian,  copaiba,  chloral,  santonine  and  hyoscyatnus  are  among  those  whose  action  must  be 
watched  most  carefully  with  a  view  to  their  incidental  effects  upon  the  skin.  Urticai'ia  from 
mental  excitement  and  from  some  obscure  affection  is  possible,  and  this  fact  must  be  some- 
times considered  in  our  treatment  of  a  case. 

Diagnosis.  If  a  typical  case  of  urticaria  is  seen  when  the  eruption  is  at  its  height  a 
difficulty  in  diagnosis  could  hardly  occur,  as  the  wheal  is  a  lesion  which  is  peculiar  to  urti- 
caria and  met  with  in  no  other  affection  of  the  skin.  But  these  lesions  are  so  evanescent  in 
character,  both  in  the  acute  and  chronic  forms  of  the  disease,  that,  like  the  toothache  which 
so  of^en  disappears  at  the  dentist's  threshold,  they  are  frequently  invisible  when  the  physi- 
cian is  called  upon  to  examine  the  patient.  In  chronic  urticaria  the  diagnosis  must  often  be 
m'jde  when  no  wheals  are  present,  but  the  characteristic  history  which  the  patient  gives  of 
lesions  occurring  suddenly,  itching  or  burning  severely  and  disappearing  speedUy  will  usually 
lead  to  a  correct  appreciation  of  the  nature  of  the  eruption.  Moreover,  in  chronic  m-ticaria 
the  excoriations  of  the  skin  which  are  left  after  the  primary  lesions  have  gone  will  serve 
often  as  a  valuable  aid  in  diagnosis.  Since  patients  subject  to  m-ticaria  present  a  character- 
istic irritability  of  the  skia,  the  following  test  maybe  resorted  to  in  aU  cases  where  a  prui-itic 
condition  of  the  skin  is  complained  of  without  apparent  lesions.  If  the  finger-nail  be  quickly 
drawn  ortr  the  skin  in  parallel  or  crossed  lines,  or  the  skin  lightly  scratched  with  any  blimt 
pointed  Jistrument,  a  hyperffimic  surface  will  be  instantly  produced,  and  in  a  few  seconds  a 
number  of  ridges  of  a  pinkish  or  whitish  hue  wU  appear.  Occasionally  patients  are  met 
with  of  a  highlv  nervous  temperament  upon  whose  skin  this  factitious  urticaria  can  be  de- 
veloped at  will.     ySee  plate.) 

Erythema  multiforme,  an  affection  closely  allied  to  urticaria,  may  be  distinguished  by 
the  persistence  of  the  lesions.  Giant  urticaria  might  be  mistaken  for  erythema  nodosum  in 
the  rare  cases  in  which  they  occur,  but  the  course  of  the  lesion  mil  here  again  serve  as  a 
guide.  Upon  the  face  urticarial  lesions  often  produce  redness  and  swelling  of  the  eyelids 
simulating  erysipelas,  but  the  affection  is  never  ushered  in  by  a  chiU  nor  accompanied  with  a 
notably  elevated  temperature. 

Treatment.  It  has  been  Avisely  remarked  that  the  difficulty  in  curing  a  disease  i'' 
always  in  direct  proportion  to  the  number  of  remedies  which  have  been  recommended  in  it> 
treatment.      Ui-ticaria  is  no  exception  to  this  rule.     Its  frequent  obstinacy  is  attested  by  th^

DISEASES  OF  THE  SKI .\ .-1JSFLA21MATVRT. 

experience  of  nearly  every  physician,  and  yet  there  is  scarcely  an  affection  of  the  skin  foi 
which  so  many  drugs  have  been  vaunted,  tested  and  discarded . 

Of  the  treatment  of  acute  urticaria  little  need  be  said.  The  cause  is  usually  ephemeral 
and  a  purely  expectant  plan  of  treatment,  though  not  to  be  recommended,  will  be  followed  in 
most  cases  by  a  speedy  return  to  health.  Since  the  eruption  is  so  frequently  due  to  the  in- 
gestion of  iiTitating  substances,  the  main  indication  for  treatment  is  to  evacuate  the 
alimentary  canal.  The  emetic  which  is  so  commonly  prescribed,  though  rarely  until  after 
the  offending  substance  has  passed  through  the  stomach,  too  often  fails  to  remove  the  source 
of  trouble,  and  only  relieves  the  eruption  by  its  temporary  effect  upon  the  cutaneous  circu- 
lation. In  urticaria  db  ingestis,  particularly  in  children,  a  dose  of  rhubarb  and  magnesia,  or 
of  castor  oil,  Avill  usually  do  far  more  good  than  an  emetic,  since  the  irritation  which  pro- 
vokes the  eruption  is  more  frequently  intestinal  than  gastric.  In  acute  urticaria  from  other 
causes  treatment  consists  almost  whoUy  in  relieving  the  distressing  pruritus  during  the  con- 
tinuance of  the  attack.  For  this  purpose  one  of  a  great  variety  of  soothing  applications  may 
be  selected.  In  my  experience  alcohol  has  proved  to  be  the  most  convenient  and  beneficial 
lotion,  and  to  obtain  the  best  results  it  should  be  merely  dabbed  upon  the  skin  with  a  sponge 
or  soft  cloth  and  allowed  to  evaporate,  the  patient  being  cautioned  not  to  rub  the  affected 
parts.  Cologne  water,  sweet  spirit  of  nitre,  vinegar  and  dilute  nitric  acid  have  also  been 
highly  recommended.  The  dependence  of  urticarial  wheals  upon  contraction  of  the  cutaneous 
muscular  fibres  would  lead  one  to  regard  the  local  use  of  chloroform  as  of  probable  value, 
and  this  has  been  verified  by  experience.  Either  of  the  following  applications  may  be 
employed : — 

9.        Chloroform    ...     10  parts.  '^.     Chloroform      ....      10  parts. 

Cold  cream,  to    .     .    50      "  Oil  of  sweet  almonds  to  .  50     " 

M.  M. 

The  use  of  baths  in  acute  urticaria  may  tend  to  excite  the  skin  and  thus  do  harm  in 
some  cases,  while  soothing  the  skin  in  other  cases,  especially  if  carbonate  of  soda  with  boiled 
starch,  bran  or  oatmeal  be  added  to  the  water.  The  eruption  is  said  to  have  disappeared 
immediately  after  plunging  the  feet  and  legs  in  hot  mustard  water. 

The  successful  treatment  of  chronic  urticaria  must  depend  upon  a  knowledge  of  its 
etiology,  and  a  diligent  study  of  the  varying  causes  of  the  disease  will  prove  far  more  condu- 
cive to  its  cure  than  any  amount  of  blind  experimentation  mth  remedies. 

A  very  important  class  of  remedies  are  those  which  tend  to  eliminate  from  the  blood  the 
imperfectly  oxidized  products  of  digestion  and  the  impurities  resulting  from  tissue  metamor- 
phosis. Of  these  the  various  alkaline  diuretics  and  saline  purgatives  \\nl\  be  found  beneficial 
through  their  tendency  to  promote  the  excretory  functions  of  the  kidneys  and  bowels,  and 
thereby  to  lessen  cutaneous  congestion. 

Since  indigestion  is  such  a  common  cause  of  urticaria,  anotlier  important  class  of  reme- 
dies are  those  which  allay  irritation  of  the  gastro-intestinal  tract     Of  these  rhubarb  and  bis

miitli  have  been  justly  praised.  The  admmisti-ation  of  sulphurous  acid  in  teaspoonful  doses 
well  diluted  is  not  particularly  palatable,  but  it  will  often  produce  a  remarkable  effect  upon 
the  eruption,  probably  by  virtue  of  its  action  in  checking  the  fermentative  changes  in  the 
ingested  food. 

A  third  class  of  remedies  are  such  as  act  mainly  upon  the  nervous  system  and  tend  to 
lessen  reflex  irritability.  This  class  comprises  a  number  of  drugs,  most  of  which  have  a 
direct  influence  upon  the  cutaneous  circulation,  and  many  of  which  have  been  known  to 
produce  an  urticarial  eruption  when  administered  in  other  diseases.  Quinine,  cinchonidia 
and  cinchona  bark  e.  g.  are  reported  to  have  both  caused  and  cured  urticaria,  and  in  many 
cases  of  intermittent  fever  it  may  be  difficult  to  decide  whether  the  drug  or  the  malaria  is  the 
cause  of  the  eraption.  "When  the  disease  occurs  in  malarial  subjects  the  drug  may  be  ex- 
pected to  do  good  in  checking  the  eruption  if  it  has  not  already  been  given  in  large  doses. 

Bromide  of  potassium  or  sodium  given  in  sufficiently  large  doses  to  produce  symptoms 
of  bromism  will  often  have  a  speedy  and  marked  effect  upon  troublesome  and  persistent  cases 
or  urticaria,  especially  such  as  owe  their  origin  to  neurasthenia  rather  than  to  indigestion. 

Belladonna  and  atropia,  salicylate  of  sodium,  arsenic,  strychina,  aconite,  balsam  of 
copaiba,  ergot  and  a  host  of  other  remedies  have  been  highly  praised  by  some  while  they  have 
signally  failed  to  manifest  their  alleged  therapeutic  power  in  other  hands.  The  apparent 
value  of  many  remedies  has  undoubtedly  been  based  partly  upon  careless  observation  and 
partly  upon  the  fact  that  the  eruption  sometimes  disappears  suddenly  for  a  short  time  without 
any  treatment  whatever. 

DERMATITIS. 

Inflammation  is  the  essential  element  of  each  disease  of  the  class  now  under  consideration, 
but  the  limitation  of  the  inflammatory  process  to  certain  anatomical  elements  of  the  skin  pro- 
duces a  variety  of  lesions  and  a  peculiar  clinical  aspect  in  every  case.  When  simple  inflamma- 
tion attacks  the  skin  as  the  result  of  definite  causes,  it  has  been  found  convenient  to  apply  the 
term  dennatitis,  with  certain  qualifying  adjectives  which  serve  to  denote  the  nature  of  the 
cause.  The  usual  symptoms  are  merely  redness,  heat,  pain  and  swelling,  but  in  some  cases 
the  lesions  common  to  other  inflammatory  affections  are  met  with.  The  grade  of  inflamma- 
tion varies  in  accordance  with  the  nature  of  the  exciting  agent,  and  the  peculiar  susceptibil- 
ity of  the  skin.  In  many  cases  we  may  have  nothing  more  than  a  simple,  or  no  >i  exudative, 
erythema,  while  in  other  cases  the  inflammatory  process  leads  to  an  eruption  of  vesicles, 
pustules  or  blebs,  and  occasionally  the  occurrence  of  gangrene. 

DERMATITIS  TRAUMATICA.  This  term  includes  the  result  of  constant  pressure  and 
severe  friction,  bruises  and  wounds  of  various  sorts,  the  stings  of  iiisects,  and  the  excoria- 
tions produced  by  the  free  use  of  the  nails  to  allay  itching.  The  cause  of  the  trouble  may 
be  generally  determined  by  careful  observation  of  the  affected  skin  in  connection  with  the 
history  which  the  patient  gives.  The  necessary  treatment  naturally  involves  an  attempted 
removal  of  the  cause,  and  will  be  suggested  by  the  nature  of  the  case.

and  sub-cutaneous  tissue  is  destroyed,  and  sloughs  of  varying  size  are  produced.  These  be- 
come loosened  by  a  suppurative  process  in  four  or  five  days,  are  gradiially  cast  off  if  not 
intentionally  removed,  and  leave  an  ulceration  which  in  time  is  followed  by  a  contractile 
cicatrix.  The  scar  which  follows  an  extensive  bum  is  always  more  or  less  puckered,  and 
presents  ridges  which  often  radiate  from  the  point  where  the  destruction  of  tissue  was  most 
marked.  When  occurring  upon  the  face,  neck  or  neighborhood  of  joints,  a  considerable 
deformity  is  often  i^roduced  by  the  gradual  contraction  of  the  cicatricial  tissue. 

The  diagnosis  of  a  bum  is  easily  made,  as  the  patient  can  easily  furnish  information  as 
to  the  active  cause.  The  lesions  of  the  skin  which  result  from  the  action  of  intense  cold,  are 
essentially  the  same  as  those  resulting  from  a  high  degree  of  heat.  A  scald  or  bum  resulting 
from  the  action  of  hot  liquids  differs  from  a  burn  produced  by  the  contact  of  iiame  or  hot 
metal,  inasmuch  as  the  hair  upon  the  surface  of  the  skin  is  immediately  destroyed  in  the 
latter  case,  but  not  in  the  former. 

The  treatment  of  burns  varies  according  to  the  nature  of  the  case ;  and  the  selection  of  a 
local  application  may  be  made  from  an  infinite  number  which  have  been  highly  recommended. 
For  a  bum  of  the  first  degi'ee,  or  even  one  more  severe,  no  better  application  can  be  made  at 
the  outset  than  a  saturated  solution  of  bicarbonate  of  soda.  This  being  usually  on  hand  in 
every  household,  can  be  applied  immediately  by  means  of  moistened  cloths,  and  in  most 
cases  it  affords  immediate  relief  from  the  pain.  Later  a  dusting  powder  of  corn  starch,  or 
precipitated  oxide  of  zinc  may  be  prescribed,  and  when  the  skin  begins  to  peel  an  emollient 
ointment  is  advisable. 

In  burns  resulting  in  the  formation  of  bullae,  it  is  important  to  protect  the  part  from 
external  '.oolence.  The  serum  confined  in  tense  blebs  may  be  evacuated  by  a  needle  prick  or 
incision  of  the  elevated  epidermis,  but  care  should  be  taken  that  this  is  not  torn  or  rubbed 
off,  ni  a  portion  of  it  may  become  reunited  to  the  skin  beneath,  and  all  of  it  serves  as  the  best 
possible  protection  to  the  raw  surface.  The  bullae,  after  careful  evacuation  of  their  contents, 
may  be  dressed  with  the  familiar  combination  of  limewater  and  linseed  oil,  or  sprinkled  over 
vrith  bismuth  powder. 

When  sloughs  have  formed,  the  best  plan  of  treatment  is  to  keep  the  parts  covered  -vvith 
ot  enveloped  in  hot  compresses  sprinlded  with  some  disinfectant  fluid.  Such  dressings,  re- 
D.owed  every  two  hours,  will  lessen  the  inflammation,  hasten  the  separation  of  the  sloughs 
and  promote  the  healing  of  the  resulting  ulcers. 

Frost-bite  (Congelatio),  or  the  cutaneous  inflammation  caused  by  exposure  to  a  very  low 
temperature,  is  characterized  by  symptoms  quite  similar  to  those  already  described  under  the 
head  of  burns.  According  to  the  intensity  of  the  cold  and  duration  of  the  exposure,  we  may 
have  a  varying  degree  of  inflammation,  varying  from  slight  redness  and  swelling  (Congelatio 
erythematosa),  to  the  formation  of  large  blebs  (c.  bullosa),  and  subsequent  sloughing  of  the 
skin  (C.  gangrenosa).  A  frost-bitten  portion  of  skin  is  at  first  white  and  stiff,  but  this  con- 
dition quickly  gives  place  to  a  dull  red  or  livid  hue  when  the  patient  enters  a  warm  atmos- 
phere. 


DISEASES  OF  TEE  SKIN.— INFLAMMATORY. 

A  frost-bite  3f  the  first  degree  frequently  affects  the  ears,  nose,  cheeks  and  hands,  and 
although  the  redness  and  swelling  usually  disappears  entii'ely  in  a  few  weeks,  it  is  not  mi- 
common  for  the  parts  to  remain  in  a  chronic  erythematous  condition  until  warm  weather 
returns,  and  in  some  cases  this  passive  hj^persemia  persists  for  years. 

The  second  degree  of  dennatitis  fi'om  cold  is  most  frequently  noted  upon  the  fingers, 
where  large  tense  bullae  form,  as  seen  in  the  illustration.  {See  plate.)  This  condition  leads 
to  superficial  ulceration,  and  frequently  to  a  temporary  loss  of  the  nails.  If  the  fluids  con- 
tained in  the  tissues  have  been  completely  frozen,  a  restoration  of  the  circulation  in  the  part 
is  not  to  be  hoped  for,  and  one  or  more  phalanges  of  the  fingers  or  toes  are  usually  lost  by 
the  subsequent  sloughing  which  inevitably  takes  place. 

The  very  first  step  to  be  taken  in  the  treatment  of  a  severe  case  of  frost-bite,  provided 
the  patient  is  ■seen  in  time,  is  to  prevent  a  too  rai)id  retiirn  of  the  circulation  in  the  affected 
part.  To  this  end  the  patient  should  be  kept  in  a  cool  or  even  cold  room,  and  compresses 
dipped  in  cold  water  applied  freely.  When  the  hands  and  feet  are  the  parts  affected,  an 
elevation  of  the  limbs  will  tend  to  lessen  the  intense  reaction,  and  thereby,  to  a  certain  ex- 
tent, control  the  consequent  dermatitis.  The  buIljB  which  fonn  should  be  pricked  or  freely 
incised,  to  allow  an  escape  of  their  serous  contents,  but  the  epidermis,  as  in  the  case  of  burns, 
should  be  retained  as  a  natural  covering  for  the  inflamed  tissue.  Should  gangrene  set  in, 
surgical  measures  should  be  promptly  resorted  to.  with  a  view  to  the  prevention  of  septic 
poisoning. 

Chilblain  (Pernio),  is  a  chronic  circumscribed  inliainination  of  the  skin,  which  occurs 
chiefly  in  the  ^^inter,  and  is  prone  to  affect  children  and  adults  of  low  vitality  and  poor 
circulation.  Its  most  common  site  is  upon  the  toes,  although  other  exposed  parts  may  be 
affected.  The  skin  is  swoUen,  of  a  bluish  red  hue,  and  a  disagreeable  burning  or  itching  is 
commonly  present.  In  the  treatment  of  this  common  and  annoying  affection,  careful  atten- 
tion must  be  paid  to  the  general  health  of  the  patient.  The  feet  must  be  warmly  clad,  and 
exposure  to  cold  and  dampness  avoided  as  far  as  possible.  Of  external  applications  a 
countless  number  have  been  recommended  and  employed  Avith  a  varying  degree  of  success. 
In  most  cases  a  stimulating  application,  such  as  spirit  of  turpentine  or  balsam  of  Peru,  may 
be  rubbed  gently  upon  the  affected  skin  at  night  with  benefit,  or  flexible  coUodion  or  solution 
of  gutta  percha  may  be  kept  constantly  applied.

ment \vill  be  found  of  value  :

DERMATITIS  VENENATA.  Under  this  head  are  classed  certain  inflammatory  condi- 
tions of  the  skin  which  result  from  the  peculiar  irritating  action  of  various  external  agents. 

(46) 


DERMATITIS. 

These  include  tlie  escharotics,  such  as  nitric  acid,  potassafusa,  and  the  various  caustic  applica- 
tions ;  the  rubefacients,  such  as  mustard,  castor  oil  and  cantharides,  and  a  number  of  poisonous 
plants.  When  applied  to  the  skin,  either  intentionally  or  accidentally,  these  exert  an  inflam- 
mation characterized  b}^  simple  redness  or  the  formation  of  vesicles  or  pustules,  and  usuallv 
of  such  a  peculiar  appearance  that  the  nature  of  the  exciting  cause  can  be  di\ined. 

One  of  the  most  interesting  forms  of  dermatitis  venenata  is  that  produced  by  the  contact 
of  the  skin  with  certain  species  of  sumach,  and  especially  the  Rhus  toxicodendron,  or  poison 
ivy,  and  the  Rhus  venenata,  or  dogwood.  The  eruption  generally  appears  upon  the  hands 
at  first,  as  these  are  most  likely  to  come  in  contact  with  the  plant,  but  usually  in  a  few  hours 
the  forearms,  face  and  frequently  the  genitals  become  similarly  affected.  The  first  symi:>tom 
of  the  eruption  which  may  not  be  noted  until  several  hours  after  the  exposure  is  a  smart- 
ing or  tingling  sensation  in  the  skin.  Erj^hematous  patches  now  develop,  upon  the  sur- 
face of  which  numerous  small  and  thickly  crowded  vesicles  soon  appear.  The  skin  often  be- 
comes swollen  and  painful,  and  in  addition  to  the  local  discomfort  a  slight  febrile  condition 
may  be  observed.  The  eruption  runs  a  course  similar  to  that  of  an  acute  eczema,  and  in  from 
five  to  ten  days  the  vesicles  have  usually  disappeared  and  given  jjlace  to  a  reddened  and  des- 
quamating condition  of  tlie  affected  jiarts.  A  fresh  outbreak  of  the  eruption  may  now  take 
place,  even  without  renewed  exposure,  and  in  this  way  the  eruption  is  sometimes  prolonged 
for  many  weeks.  Some  patients  who  have  suffered  severely  from  ivy  poisoning  ^^dll  com^^lain 
of  an  eczematous  eruption,  which  seems  to  occur  every  year  upon  the  face  and  hands  at  about 
the  time  of  the  year  when  they  were  first  affected. 

There  is  a  marked  difference  in  the  susceptibility  of  persons  to  this  i)eculiar  eruption. 
While  some  can  handle  the  i^lant  with  impunity,  and  even  rub  the  leaves  or  juice  exuding  from 
the  broken  stems  upon  their  skin  without  exciting  the  slightest  dermatitis,  there  are  others 
who  become  affected  in  a  marked  degree  by  the  i^oisonous  exhalation  which  pervades  the  im- 
mediate vicinity  of  the  fresh  plant.  I  have  a  patient  who  assures  me  that  he  cannot  drive 
through  v.-oods  where  the  poison  siimach  abounds  without  subsequently  suffering  from  the 
charactei'istic dermatitis,  and  that  merely  passing  to  the  leeward  of  a  field  where  farmers  were 
burning  brush  has  repeatedly  been  sufficient  to  evoke  the  eruption.  The  poisonous  influence 
is  frequently  carried  in  gloves  and  other  articles  of  clothing,  and  in  knives  which  have  been 
employed  in  cutting  the  leaves  or  branches,  and  thereby  certain  susceptible  individuals  may 
be  unexpectedlj'  affected.  Physicians  have  been  known  to  handle  the  rhus  without  injury  to 
themselves  but  with  detriment  to  susceptible  patients  whose  skins  they  have  shortly  after- 
wards touched  and  j)oisoned. 

Diagnosis.  The  eruption  resulting  from  ivy  poisoning,  when  seen  at  its  height,  can 
only  wdth  difficulty,  if  at  all,  be  distinguished  from  an  outbreali  of  acute  eczema.  But  the 
characteristic  localization  of  the  eruption  upon  the  hands,  face  and  genital  region  will  usually 
excite  suspicion  as  to  its  nature,  and  the  history  which  the  patient  often  gives  of  having  been 
in  the  woods  just  before  the  outbreak  of  the  eruption  will  serve  to  verify  the  diagnosis. 

Treatment.     There  are  few  affections  of  the  skin  for  which  a  greater  number  and  variety 

(47) 


DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

of  remedies  have  been  recommended  than  for  the  dermatitis  of  rhus  poisoning.  A  mere  list 
of  them  woald  require  several  pages,  and  though  many  of  them  have  been  vaunted  as  infal- 
lible, it  is  probable  that  most  of  them  have  been  tried  in  vain  by  other  and  less  enthusiastic 
physicians.  It  is  extremely  doubtful  whether  there  is  any  specific  remedy  which,  given  inter- 
nally or  applied  locally,  will  cut  short  the  attack,  and  yet  much  may  be  done  to  relieve  the 
suffering  of  the  patient.  Enforced  rest,  light  diet  and  cooling  drinks  wiU  prove  of  benefit  in 
every  severe  case,  while  smaU  doses  of  gelseminum  or  grindelia  robusta  will  certainly  do  no 
harm.  Of  local  remedies  the  one  which  I  have  found  to  be  as  valuable  as  any  of  the  number 
which  I  have  tried,  is  lime  water.  If  this  is  applied  frequently  by  means  of  linen  cloths  dur- 
ing the  height  of  the  eruption,  a  soothing  effect  may  be  expected.  The  liquor  sods  chloratse 
may  also  be  used  to  advantage,  either  pure  or  diluted,  with  rain  water.  When  the  acute 
infiammation  has  subsided  a  soothing  ointment  will  protect  the  tender  skin  and  prove  less 
troublesome  in  its  application  than  the  lotion. 

ECZEMA. 

Synonyms — Salt  rheum.     Moist  tetter. 

Eczema  is  the  most  common  affection  of  the  skin  which  the  physician  is  called  upon  to 
treat.  According  to  the  various  statistics  of  private  and  dispensary  practice,  it  includes 
about  one-third  of  all  the  cases.  It  occurs  at  all  ages,  in  both  sexes,  and  among  all  classes. 
There  is  scarcely  a  family,  rich  or  poor,  of  which  some  member  has  not  suffered  at  some  pe- 
riod in  his  lifetime,  from  eczema  in  a  slight  or  more  severe  form.  It  is  furthermore  one  of 
the  most  annoying  affections  to  which  the  skin  is  heir,  and  this  fact,  coupled  with  that  of  its 
frequency,  renders  it  beyond  doubt  the  most  important  of  all  skin  diseases  and  one  with 
which  the  physician  should  be  most  familiar.  The  disease  is  always  amenable  to  proper 
treatment,  and  in  no  field  of  medical  practice  can  the  physician  more  readily  secure  reputation 
and  reward  than  in  the  diagnosis  and  cure  of  Eczema. 

The  term  eczema  (from  e«  and  Ctu  ),  meaning  "to  boil  out,"  or  "effervesce,'"  implies  a 
catarrhal  condition  of  the  skin.  A  moist  surface,  or  at  least  a  tendency  of  the  affected  skin 
to  become  moist  through  exudation  of  a  gummy,  albuminous  serum,  is  the  chief  character- 
istic of  the  disease.  It  has  been  claimed  that  a  moist  surface  is  always  present  at  some  time 
in  the  course  of  the  disease,  but  clinical  experience  shows  that  cases  of  erythematous  and 
papular  eczema  may  remain  dry  from  beginning  to  end.  Even  these  cases,  however,  evince 
a  tendency  to  develop  a  moist  sm-face  upon  slight  external  irritation,  and  moist  patches  are 
not  infrequently  found  upon  an  extensive  eruption  which  elsewhere  is  perfectly  dry.  Fre- 
quently patients  will  state  that  their  eczema,  now  in  its  decline,  has  always  been  drj%  and 
the  thickened  patch  of  skin  may  appear  to  be  due  to  increased  cellular  growth  or  some  cause 
other  than  infiltration  of  the  sldn  with  a  serous  fluid.  If  the  scaling  epidermis  be  rubbed 
briskly  with  soap  and  a  piece  of  I'ough  cloth  it  will  be  readily  removed,  and  the  catarrhal, 
and   hence  the  eczematous   nature   of  the   patcli,   will  be  revealed   by   the  minute  pearly 

(48) 


ECZEMA    ERYTHEMATOSUM 


tOTTPE,  E.  BIERSTADT,  N.  Y. 


ECZEMA. 

beads  of  serum,  which  ooze  out  on  the  surface  of  the  partially  denuded  corium.  It  is  iLIj 
tendency  to  exudation  upon  the  surface  of  the  skin  which  distinguishes  a  patch  of  eczema 
from  simple  inflammation  or  dermatitis. 

The  exudation  in  eczema  varies  in  amount,  being  so  slight  in  some  cases  as  not  to  appear 
upon  the  surface,  while  in  others  it  is  poured  out  so  abundantly  that  the  whole  epidermis  is 
washed  away  and  a  smooth  red  patch  is  exposed.  It  varies  also  in  character.  In  some  cases 
the  exudation  is  plastic,  and  being  retained  in  the  cutaneous  tissue  produces  papulation  on 
the  surface,  and  infiltration  and  hardening  of  the  subcutaneous  cellular  tissue,  while  in  other 
cases  it  readily  permeates  the  cells  of  the  rete,  and  elevates  the  horny  layer  in  the  form  of 
vesicles.  Upon  the  surface  of  the  skin  the  exudation  feels  sticky,  and  cloths  or  banda<^es 
soaked  by  it  stiffen  upon  drying,  and  appear  stained.  In  strumous  and  ill-conditioned  sub- 
jects, the  exudation  assumes  a  purulent  character.  This  variation  in  the  character  of  the 
exudation  results  in  a  variety  of  lesions,  no  one  of  which  has  any  claim  to  be  regarded  as  the 
special  lesion  of  eczema.  The  disease  is  not  merely  a  vesicular  affection,  as  it  was  classed  by 
the  earlier  dermatologists,  but  is  frequently  papular  and  pustular  as  well,  and  in  many 
instances  there  is  no  vesiculation  from  beginning  to  end.  When  the  surface  exudation  is 
profuse,  the  serum  dries  and  forms  crusts.  The  crust  of  typical  eczema  is  thin  and  dark, 
cracking,  and  allowing  the  exudation  to  ooze  from  the  cracks.  Often  it  is  composed  partly 
of  dried  blood,  the  result  of  scratching.  When  the  exudation  is  purulent,  the  crusts  are 
lighter  in  color  and  thicker,  increasing  in  bulk  by  augmentation  from  beneath.  The  exuda- 
tion is  sometimes  of  a  thick,  honey-like  character,  producing  a  bright  yellow  crust. 

The  thickening  of  the  skin  in  eczema  is  most  marked  in  chronic  cases.  It  is  partly  due 
to  cellular  infiltration,  and  partly  to  the  exudation  of  plastic  serum  into  the  subjacent  areolar 
tissue.  In  acute  cases  and  in  parts  of  the  body  liable  to  passive  congestion,  e.  g.  the  legs,  a 
temporary  oedema  often  increases  the  thickness  of  the  integument. 

The  itching  of  a  patch  of  eczema  is  a  feature  which  is  rarely  absent,  but  on  the  contrary^ 
usually  present  in  a  marked  degree.  In  adults  it  is  apt  to  be  most  troublesome  in  the  ery- 
thematous and  papular  forms  of  the  disease.  In  children  it  is  xisually  severe,  although,  in 
the  jDustular  form  which  occurs  so  often  in  those  of  a  strumous  diathesis,  the  symptom  may 
be  much  less  marked. 

The  pathological  process  which  takes  place  in  the  affected  skin  consists  mainly  in  con- 
gestion and  cell-proliferation.  In  some  cases  the  congestion  is  the  main  feature,  and  the- 
affection  is  only  to  be  distinguished  from  erythema  by  the  characteristic  pruritus  and  des- 
quamation. In  most  cases,  however,  there  are  marked  cellular  changes,  as  has  been  shown 
by  microscopical  examination.  The  disease  in  its  mildest  form  may  begin  as  a  simple  h  j^iei'- 
gemia.  The  skin  becomes  sightly  thickened,  itches  more  or  less,  and  finally  desquamates. 
Usually,  however,  the  initial  hyperemia  is  followed  by  the  development  of  papules,  vesicles^ 
or  pustules.  Pruritus  and  exudation  become  prominent  features,  and  eventually  the  affected 
skin  desquamates,  as  in  the  fonner  instance.  The  disease,  then,  alwaj's  begins  in  hyperaemia 
and  ends   in  desquamation.     It  is  characterized   by  a  tendency  to  moisture  of  the  surfacf,

which  may  result  in  crusting,  by  infiltration  of  the  deeper  tissues  which  produces  thicken- 
ing, by  the  development  usually  of  papules,  vesicles  or  pustules,  and  by  slight  or  severe 
itching. 

Following  Willan.  the  illusti'ious  pioneer  of  English  Dermatology,  some  wi-iters  ha\e 
divided  eczema  into  a  mild  variety  {E.  simplex),  an  inflammatory  variety  {E.  rubrum),  and  a 
purulent  variery  {E.  im'petiginodes).  This  division  is  rather  broad  and  indefinite,  and  as 
many  cases  do  not  fall  naturally  into  one  of  the  three  classes,  it  is  of  little  practical  value. 
As  a  guide  in  the  study  of  the  disease,  an  aid  in  the  description  of  cases,  and  a  hint  as  to  the 
requisite  mode  of  treatment,  it  is  a  better  plan  to  divide  eczema  into  stages  through  which 
the  majority  of  cases  pass  in  their  progress  toward  recovery,  and  to  classify  all  cases  in  accord- 
ance with  certain  well-marked  clinical  forms  or  phases  assumed  by  the  eruption,  and  to 
which  a  special  nomenclature  is  applicable. 

The  stages  of  eczema  are  three.  The  initial  stage  is  characterized  mainly  by  hypersemia, 
with  slight  interstitial  exudation,  and  in  most  cases  by  an  eruption  of  papules,  vesicles,  or 
pustules.  Tliis  lasts  but  a  few  days  or  weeks  at  the  most  before  passing  into  the  second 
•  stage,  which  is  characterized  by  exudation  and  crusting.  The  extidation  may  be  serous  or 
sero-purulent  in  character,  and  the  inflammatory  sjonptoms  are  usually  well-marked.  The 
surface  exudation  destroys  the  integrity  of  the  epidermis  and  dries  into  light-colored  crusts 
when  not  mingled  with  blood,  which  often  flows  freely  from  numerous  excoriations.  The 
second  stage  of  eczema  is  of  indefinite  duration  ;  but  sooner  or  later  the  exudation  subsides, 
the  crusts  fall,  leaving  a  thin,  newly-formed  epidermis,  and  we  have  then  the  third  or  term- 
inal stage,  characterized  by  desquamation  and  a  certain  amount  of  inditration  of  the  affected 
pait.  In  some  instances-the  initial  stage  passes  directly  into  the  terminal  stage,  without  the 
occurrence  of  extidation  upon  the  surface  or  the  development  of  any  lesion  besides  the  ery- 
thematous patch,  and  not  infrequently  the  third  stage  relapses  into  the  second,  the  scaling 
surface  again  becoming  moist.  Very  often  a  case  of  eczema  will  exhibit  the  three  stages  on 
different  portions  of  the  skin  at  the  same  tizne.  At  the  spreading  margin  of  an  exuding 
patch  (second  stage)  we  see  hyperjemia  and  vesiculation  (first  stage),  while  a  neighboring  patch 
may  have  become  dry  and  scaly  (third  stage).  The  terms  "acute"  and  "chronic,"  a, -i  ap- 
plied to  eczema,  are  conveniently  used  in  describing  cases,  and  are  always  suggestive  of  the 
appropriate  plan  of  treatment ;  but  it  must  be  borne  in  mind  that  these  terms,  as  commonly 
employed,  do  not  refer  so  much  to  the  length  of  time  which  the  eruption  has  existed  as  to 
the  grade  of  inflammation  which  it  presents.  An  eczema  of  thirty  years'  standing  might, 
therefore,  during  an  exacerbation,  be  regarded  as  an  acute  eczema,  and  treated  as  such  itntil 
the  inflammatory  symptoms  have  subsided. 

The  clinical  forms  of  eczema  are  numberless,  and  innumerable  expressive  tenns  have  been 
coined  and  applied  to  them.  It  is  simply  a  question  of  convenience  whether  we  shall  employ 
five  terms  or  fifty  for  purposes  of  description.  Certain  it  is,  however,  that  there  are  six  strik- 
ing phases  assumed  by  eczema,  and  in  accord  with  Wilson,  the  most  admirable  wi-iter  on  this 
disease,  the  following  clinical  forms  wiU  be  described  : 

(50) 


ECZEMA. 

1.  Eczema  erythematosmn  (Pityriasis). 

2.  Eczema  papillosum  CLichen  simplex). 

3.  Eczema  vesiciilosum. 

4.  Eczema  ichorosmn  (E.  madidans.     E.  rubnun). 
6.  Eczema  pustulosum  (E.  impetiginosum). 

6.     Eczema  squamosum. 

The  first  two  and  last  of  these  forms  are  always  dry  {E.  siccum),  while  the  remaining 
three  are  more  or  less  moist  (^.  Jiumidum),  although  the  moist  surface  is  sometimes  concealed 
by  a  crust.  These  forms  of  eczema  may  be  accompanied  by  exceptional  peculiarities,  such  at> 
a  circumscribed  border,  the  existence  of  oedema,  and  the  development  of  tubercles,  fissure;^ 
or  a  warty  surface.  The  term  Eczema  marginatum  is  applied  to  an  erythematous  or  papulai 
patch  which  does  not  shade  off  at  its  borders,  as  is  commonly  the  case  in  eczema.  The  con- 
dition is  frequently  seen  about  the  genito-crural  folds,  and  is  likely  to  be  confounded  with 
trichophytosis  of  this  i-egion,  of  which  it  is  sometimes  a  sequel.  The  tenn  Eczema  rimosum 
{E.  fissum)  is  used  when  a  squamous  or  ichorous  eczema  of  the  hand  or  of  the  flexure  of 
joints  is  accompanied  by  the  development  of  numerous  fissures  (see  plate  of  E.squaviosum). 
Eczema  verrucosum  indicates  a  warty  condition,  most  frequently  seen  near  the  ankle,  and  gen- 
erally in  connection  with  ulceration.  These  accidental  features  are  of  little  importance,  and 
cases  of  eczema  exhibiting  them  will  be  found  to  fall  naturally  into  one  of  the  six  divisions. 

The  older  wi-iters  on  Deimatology  were  specially  disposed  to  indulge  in  the  use  of  a  great 
variety  of  adjectives  to  indicate  the  peculiar  featui'es  of  eczema,  and  Bulldey  has  made  a  col- 
lection of  the  terms  thus  employed,  and  has  found  that  not  less  than  one  hundred  and  twenty- 
five  Latin  names  have  been  given  to  the  phases  of  this  one  eruption. 

Erythematous  eczema,  as  the  name  implies,  is  characterized  mainly  by  hypersemia. 
There  are  no  vesicles,  pustules,  or  well  marked  papules,  no  moisture — nothing  but  a  tolerably 
smooth,  reddened  surface,  with  a  moderate  amount  of  fine  desquamation.  In  its  incipient 
form  it  is  merely  a  persistent  erj-thema,  with  slight  infiltration  of  the  skin  and  consequent 
pruritus.  By  scratching,  or  other  external  irritation,  the  skin  may  become  considerably 
thickened  and  covered  with  fine  branny  scales.  This  form  (classed  with  E.  squamosum  by 
Hebra,  and  described  as  pityriasis  by  older  writers)  is  frequently  met  with  on  the  face,  and 
usually  predominates  when  the  disease  extends  over  the  greater  portion  of  the  body.  In  the 
plate  of  E.  universale  it  is  seen,  together  with  patches  of  the  ichorous  and  the  squamous  form. 

When  hyperfemia,  which  is  the  distinguishing  feature  of  both  erythematous  and  papu- 
lar eczema,  is  not  merely  confined  to  the  superficial  network  of  blood  vessels,  as  in  the  ery- 
thematous form,  but  involves  also  the  follicular  plexuses,  we  have  discrete  congestive 
papules  developed  upon  a  reddened  patch  of  skin.  This  papidar  eczema  may  be  transitory 
when  produced  by  external  agencies  (a  poultice  of  Avater-dressing,  e.  g.),  but  it  is  often  chronic 
and  obstinate.  When  the  congested  follicles  are  not  seated  upon  a  hypergemic  and  infiltrated 
patch,  but  are  scattered  in  groups  upon  the  normal  skin,  the  term  lichen  simplex  has  been 

(51) 


DISEASES  0I>  TEE  SKIN.— INFLAMMATORY. 

used  to  denote  the  condition.  "\"\Tiile  it  is  convenient  for  purposes  of  description  to  use  the 
old  terms  lichen  and  impetigo,  it  must  always  be  borne  in  mind  that  they  are  not  distinct 
affections,  but  merely  modifications  of  the  papular  and  pustular  forms  of  eczema. 

Vesicular  eczema  was  formerly  regarded  as  the  type  of  the  disease.  Vesicles,  however, 
are  rarely  present  in  cases  of  eczema  when  seen  by  the  physician,  and  hence  are  of  little  use  in 
diagnosis.  In  many  cases  there  has  been  neither  vesiculation  nor  even  a  moist  surface 
throughout  the  course  of  the  disease.  The  vesicular  form  of  eczema  is  quite  uncommon.  It 
consists  of  numerous  small  acuminate  vesicles,  crowded  together  upon  a  highly-congested 
base.  It  may  rim  an  acute  course,  and  terminate  in  a  week  or  ten  days  (and  this  is  usually 
the  case  when  it  is  due  to  the  action  of  some  severe  local  initant),  or  the  exudation  may  con- 
tinue after  a  rupture  of  the  vesicles,  and  the  disease  then  assumes  the  ichorous  fonn.  Vesicu- 
lar eczema  attacking  the  face  is  often  mistaken  for  erysipelas,  especially  when  its  outbreak 
is  accompanied  by  slight  fever.  The  smooth,  tense  skin,  Avith  an  abrupt  margin  of  the  patch, 
is  not  seen,  however,  in  eczema,  and  the  speedy  development  of  fine  vesicles,  or  an  exuding 
surface,  dispels  all  doubt. 

In  the  ichorous,  or  moist  fomi  of  eczema,  we  have  the  condition  of  most  frequent  occur- 
rence. The  affected  part  is  swollen  and  tender,  and  the  surface  either  presents  a  reddened, 
raw  appearance  {E.rubrum),  or  is  covered  by  a  thin,  dark  crust,  through  which  and  beneath 
which  the  characteristic  gummy  exudation  appears.  A^esiculation  may  or  may  not  have 
preceded  this  condition.  The  exudation  may  have  permeated  the  epidermic  cells  and  washed 
them  away  en  masse.  Indeed,  a  moist  surface  may  be  present  in  some  cases  without  even 
destruction  of  the  epidennis.  When  folds  of  skin  lie  in  contact,  as  they  do  about  the  nec!c 
and  joints  of  fat  babies,  and  beneath  the  breasts  and  in  the  inguinal  region  of  obese  females 
the  epidermis  becomes  macerated,  and  frequently  assumes  the  character  of  epithelium.  For 
a  short  time  the  skin  may  appear  as  though  converted  into  a  mucous  membrane,  and  dis- 
charge a  viscid  serum  {B.  mucosum).  Eczema  ichorosum,  in  which  the  disease  is  at  its 
height,  cannot  be  well  confounded  with  any  other  affection  of  the  skin. 

The  pustular  form  is  in  some  cases  not  readily  distinguished  from  the  ichorous  form. 
The  exuding  s'jrum,  instead  of  being  clear  and  waterj",  may  be  thicker,  honey-like  con- 
sistence, and  dry  into  yellowish  crusts.  The  contents  of  the  vesicles  may  assume  a  sero-puru- 
lent  character,  or  pustules  may  be  scattered  over  the  surface  along  with  the  vesicle,  while  in 
either  case  yellowish  or  slightly  brownish  crusts  are  formed,  which  increase  in  thickness 
from  additions  to  the  under  surface.  Pustular  eczema  is  common  in  strumous  and  poorly- 
nourished  subjects.  It  is  very  apt  to  appear  in  connection  with  scabies  and  with  phtheiriasis 
both  of  the  body  and  of  the  head.  Isolated  pustules  are  frequently  developed  when  external 
initation  coincides  wdth  impaired  energy,  e.  (/.,  after  a  season  of  intensely  hot  weather,  but 
it  is  an  open  question  as  to  whether  these  are  justly  regarded  as  being  eczematous  in  nature. 
Though  eczema  commonly  leaves  no  scars,  this  pustular  form,  the  "milk-crust"  of  infancy, 
sometimes  pits  the  cheeks,  and,  even  in  later  years,  the  child  shows  marks  which  might  be 
mistaken  for  the  effect  of  variola. 

(62) 


ECZEMA. 

The  squamous  form  is  the  terminal  stage  of  one  of  the  other  forms.  It  is  but  an  ex;;  "- 
geration  of  the  erythematous  form — the  acute  hypersemia  and.  branny  desquamation  giving 
place  to  thickening  and  induration  of  the  skin  and  subjacent  tissue,  with  exfoliation  of  the 
epidermis.  It  sometimes  occurs  in  patches  upon  the  extensor  siu-face  of  the  extremities, 
when  it  is  with  difficulty  distinguished  from  psoriasis.  The  gi-adual  shading  ofl'  of  the 
patches  at  the  margins,  contrasted  with  the  circumscribed  border  of  psoriatic  scales,  and  the 
existence  of  moisture  beyond  that  condition  which  exists  in  psoriasis  when  tlie  scale  is  re- 
moved and  the  corium  exposed,  are  features  which  'ndll  usually  determine  the  diagnosis. 
Squamous  eczema,  when  universal,  resembles  Dermatitis  exfoliati\a  ;  but  in  this  rare  affec- 
tion the  flakes  of  epidermis  are  much  more  abundant,  there  is  no  thickening  of  the  ?kin,  no 
moist  patches,  no  severe  itching,  and  frequently  there  is  a  high  grade  of  fever  and  great 
prostration. 

According  to  the  German  school,  eczema  is  a  local  disease,  and  usually  independent  of 
any  constitutional  vice  or  humor.  External  treatment  is,  therefore,  of  the  greatest  curative 
value.  The  idea  of  "driving  in"  the  eruption,  or  of  its  possible  metastasis  to  some  internal 
organ  is  rejected,  and  the  relapse  Avhich  so  often  occurs  in  eczematous  patients  is  referred  to 
perverted  cell-groMh  of  the  affected  part  rather  than  to  any  disposition  to  the  affection  exist- 
ing throughout  the  economy. 

The  French  school  has  always  been  the  champion  of  the  constitutional  nature  of  eczema. 
The  dartrous  diathesis  which,  emigrating  to  Ameiica,  appears  as  the  rheumic  diathesis,  is 
a  term  employed  to  indicate  that  general  condition  of  which  the  eniption  in  eczema  (and 
psoriasis  as  well)  is  believed  to  be  a  mere  outward  expression.  The  local  treatment, 
according  to  the  supporters  of  this  view,  is  of  minor  importance,  and  a  radical  cure  is  only 
to  be  obtained  by  remedies  aimed  at  the  constitutional  defect. 

The  English  writers  on  dennatology,  while  not  generally  accepting  this  view  of  the  dia- 
thetic nature  of  eczema,  lay  great  stress  upon  it.s  association  with  and  dependence  upon 
gout,  rheumatism,  dyspepsia,  etc.,  in  a  large  proportion  of  cases,  and  are  more  disposed  to- 
favor  a  judicious  combination  of  internal  and  external  remedies.  In  America,  these  opposing- 
views  meet  on  a  common  ground,  and  time  will  tmdoubtedly  declare  the  "survival  of  the 
fittest.'" 

The  predisposing  causes  of  eczema  are  not  thoroughly  understood.  There  are  plenty  to 
be  found  outside  of  the  profession  who  satisfy  themselves  by  saying  that  it  arises  from  "  heat 
in  the  blood,"  or  "  bad  humor,"  or  "  scurvy,"  and  there  are  many  able  writers  in  the  pro- 
fession who  delude  themselves  into  the  belief  that  everything  is  clear  when  tlie  disease  is 
ascribed  to  "assimilative  debility,"  "perverted  innervation,"  or  to  some  favorite  "diathesis." 
Piffard,  an  able  champion  of  the  "rheumic."  diathesis,  claims  that  -eczema,  psoriasis  and 
pityriasis  exhibit  certain  general  characteristics  which  indicate  a  mutual  relationship,  and 
mentions  the  following  features  which  they  possess  in  common  : 

They  are  not  contagious.

DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

They  are  frequently  general ;  not,  however,  by  simultaneous  invasion  of  the  surface,  but 
by  spreading  from  dliferent  foci. 

They  are  frequently  symmetrical. 

They  are  usually  chronic. 

Their  natural  duration  is  indefinite. 

They  are  obstinate  and  do  not  readily  yield  to  treatment. 

They  are  frequently  observed  in  different  members  of  the  same  family. 

T^vo  or  more  forms  may  be  present  at  the  same  time,  or  may  appear  successively. 

They  do  not  always  preserve  their  individuality,  but  sometimes  merge  one  into  the  other. 

Relapses  are  frequent. 

They  sometimes  alternate  with  affections  of  other  organs,  especially  of  the  pulmonary 
and  gasti-ic  mucous  membranes  and  of  the  joints. 

niey  itch. 

The  lesions  are  always  superficial. 

They  never  leave  cicatrices. 

They  are  more  or  less  amenable  to  certain  definite  methods  of  treatment,  which  have 
little  if  any  effect  upon  oth^'  cutaneous  affections. 

We  know  that  eczema  is  frequently  associated  with  a  rheumatic  tendency,  and  with  some 
of  the  many  phases  of  dyspepsia,  and  that  it  is  aggravated  by  poor  food,  intemperate  habits, 
care,  and  overwork  Its  association  with  dentition,  gestation,  worms,  diabetes,  etc.,  has 
been  noticed  so  often  as  to  suggest  a  relationship,  and  the  fact  should  not  be  lost  sight  of 
when  ( ailed  upon  to  treat  the  disease.  If  not  hereditary  in  many  instances,  it  is  certainly 
more  prone  to  occur  among  those  who  inherit  the  delicate  and  irritable  skin,  and  the  rheu- 
matic and  gouty  tendencies  of  their  eczematous  progenitors.  The  exciting  causes  are  mostly 
local.  Any  continued  irritant  of  mechanical  or  chemical  nature  wiD  produce  an  eczema  upon 
almost  any  skin,  and  all  the  more  readily  when  some  of  the  predisposing  causes  exist.  The 
use  of  over-stimulating  ointments  in  other  skin  affections — as  sulphur  in  scabies,  mercurial 
ointment  in  phtheiriasis  pubis — often  evokes  an  eczema.  Grocers,  bakers,  bricklayers,  and 
others  engaged  in  pecidiar  occupations,  often  acquire  eczema  upon  the  hands  and  other  parts 
exposed  to  the  irritating  action  of  sugar,  lime,  brick-dust,  etc.  Persistent  moisture  favors 
the  development  of  the  disease,  and  hence  infants  and  corpulent  adults  are  often  affected 
where  the  folds  of  the  skin  come  in  contact.  Washerwomen  are  very  prone  to  a  severe 
eczema  of  the  hands,  which  is  often  incui-able  so  long  as  the  hands  are  frequently  in  water. 

Diagnosis.  Eczema  is  the  most  protean  of  cutaneous  affections.  Occurring,  as  it  does, 
at  any  age  and  upon  any  jiortion  of  the  body,  and  presenting  the  greatest  variety  of  lesions, 
it  is  capable  of  assuming  a  similitude  to  almost  any  affection  of  the  skin.  In  ordinary  cases 
it  is  readily  recognized,  but  when  it  does  not  present  a  typical  form  it  is  frequently  mistaken 
for  some  other  disease.  The  advice  which  has  been  jokingly  given  to  call  every  doubtful 
<Tuption  a  case  of  eczema  is  not  at  all  bad,  for  in  nearly  every  doubtful  case  the  diagnosis  of 
eczema  must  be  considered,  and  where  the  doubt  can  not  be  expelled  the  physician  will  do 

(54) 


ECZEMA. 

better  to  consider  it  as  eczema  and  endeavor  to  cure  it  by  attention  to  the  patient's  genei-al 
health,  than  to  regard  it  as  a  possible  manifestation  of  syphilis,  and  acting  upon  this  suspi- 
cion to  subject  the  patient  to  an  unnecessary  course  of  specific  medication. 

In  the  diagnosis  of  eczema  the  characteristic  symptoms  of  the  eruption  must  be  borne  in 
mind,  and  if  the  case  in  question  presents  redness  and  thickening  of  the  skin,  scaling  or 
crusting,  a  tendency  to  moisture,  and  a  severe  pruritus,  the  diagnosis  is  evident.  But  some 
of  these  symptoms  may  be  absent,  and  it  will  be  often  f oimd  necessary  to  consider  the  char- 
acteristics of  certain  other  affections  which  may  be  suggested  by  the  clinical  appearances  of 
the  case  and  then  arrive  at  a  diagnosis  of  eczema  by  a  process  of  exclusion.  The  thickening 
of  the  skin  in  eczema  is  sometimes  too  slight  to  serve  as  a  basis  of  diagnosis  and  as  has  been 
already  stated,  the  moist  surface  is  not  an  essential  feature  of  the  disease.  The  itching  of 
the  skin,  however,  is  always  present  and  most  serviceable  in  suggesting  the  eczematous  nature 
of  the  disease. 

In  the  diagnosis  of  skin  diseases  in  general  it  is  often  a  good  plan  to  regard  them  aU  as 
belonging  to  two  classes,  viz. :  those  which  itch  and  those  which  do  not  itch.  If  the  eruption 
is  not  at  all  itchy  (and  to  decide  this  point  it  is  far  better  to  look  for  evidences  of  scratch- 
ing upon  the  skin  than  to  inqidre  of  the  patient),  it  is  evident  that  it  is  not  eczema,  urticaria, 
scabies,  phtheixiasis  or  any  other  affection  belonging  to  the  first  of  the  two  classes.  On  the 
other  hand,  if  the  lesions  are  excoriated  and  the  skin  decorated  by  numerous  scratch  marks, 
we  know  that  the  eruption  can  not  be  of  a  syiDhUitic  origin,  or  one  of  those  of  the  second 
class,  in  which  there  is  little  or  no  prui-itus.  Unfortimately  for  the  perfect  working  of  this 
plan  of  diagnosis  there  are  some  affections  which,  like  erythema  multiforme,  burn  or  itch  in 
a  slight  degree — or  like  psoriasis,  may  cr  may  not  itch — but  nevertheless  it  often  enables  one 
to  narrow  the  possibilities  of  diagnosis  to  a  considerable  extent. 

The  erythematous  form  of  eczema  may  be  mistaken  for  erythema,  erysipelas,  rosacea  and 
pityriasis.  Simple  erythema  differs  from  a  mild  case  of  erythematous  eczema  in  a  very  sligh' 
degree.  There  is  no  thickening  of  the  skin,  the  surface  not  at  all  scaly  save  in  exception?^  i 
instances  where  an  extensive  desquamation  follows  the  hypersemia  and  the  sensation  accom- 
panying the  eruption  is  one  of  burning  rather  than  itching.  Erythema  multiforme  is  usually 
distinguished  by  its  characteristic  localization  on  the  backs  of  the  hands,  or  by  its  margiiiate 
configuration  when  occurring  upon  the  trunk.  When  eczema  occurs  in  an  acute  form  r.pon 
the  face  of  an  adult,  the  stidden  redness  and  swelling  of  the  skin  is  very  apt  to  lead  to  a 
diagnosis  of  erysipelas,  but  the  absence  of  fever,  the  occtirrence  of  vesicles  or  surface  exuda- 
tion in  place  of  bullse,  and  the  course  of  eruption,  will  soon  reveal  the  mistake. 

Rosacea  occiu-ring  in  old  men  with  weather-beaten  faces,  often  presents  a  counterfeit  ap- 
pearance of  erythematous  eczema  of  the  forehead,  nose  and  cheeks.  In  the  former  affection 
the  congestion  is  of  a  chronic  passive  character,  and  the  skin  feels  cool  to  the  touch,  while  in 
the  latter,  the  congestion  is  active,  and  accompanied  by  an  elevated  temperature  and  severe 
itching.     Pityriasis  might  be  considered  as  the  mildest  form  of  erythematous  or  squamous 

(65) 


DISEASES  OF  TEE  SKIN.— INFLAMMATORY. 

eczema.  In  its  clinical  appearance  it  differs  only  in  being  more  superficial,  and  not  present- 
ing the  bright  red  color  and  annoying  pruritus  of  eczema. 

The  papular  form  of  eczema  may  be  confounded  with  scabies,  phtheiriasis,  urticaria, 
lichen  planus  and  syphilis.  In  scabies,  indeed,  the  eruption  is  nothing  more  than  an  artifi- 
cial papular  eczema,  but  the  extent  of  the  eruption,  its  peculiar  localization,  and  the  history 
of  contagion,  even  without  the  discovery  of  the  characteristic  burrows  of  the  itch  mite,  will 
serve  to  indicate  the  parasitic  origin  of  the  disease.  In  both  scabies  and  phtheiriasis  the 
eruption  is  largely  due  to  the  action  of  the  finger  nails  upon  the  skin,  and  there  never  co-ex- 
ist patches  of  moist  and  thickened  skin,  such  as  inevitably  accompany  an  extensive  eruption 
of  papular  eczema. 

It  should  be  borne  in  mind,  however,  that  a  secondary  eczema  is  not  infrequently  pro- 
duced in  these  parasitic  cases  by  the  irritation  of  the  skin,  and  hence  a  double  diagnosis  is  of- 
ten necessary.  Urticaria  could  not  be  mistaken  for  anything  else  if  it  were  always  seen  at  its 
height,  but  inasmuch  as  the  wheals  have  often  disappeared  when  the  patient  seeks  relief,  and 
nothing  is  left  upon  the  skin  but  a  number  of  excoriations  and  papules  which  have  resulted 
from  scratching,  the  diagnosis  of  papular  eczema  can  only  be  excluded  after  a  consideration 
of  the  history  of  the  case.  Lichen  planus  differs  from  papular  eczema  in  the  peculiar  char- 
acter of  the  lesions, which  are  low,  flat,  and  often  angular  in  outline,  and  with  a  shining  sur- 
face and  a  central  depression.  These  lesions  are  very  apt  to  form  patches,  but  a  tendency  to 
moisture  or  crusting  is  never  observed.  Lichen  ruber  is  too  rare  and  too  severe  a  disease  to 
be  often  mistaken  for  eczema.  The  miliary  papular  syphilide,  on  the  other  hand,  has  fre- 
quently jiassed  unrecognized,  and  been  treated  for  eczema  until  other  undeniable  manifesta- 
tions of  syphilis  have  made  the  error  apparent.  The  eruption  in  the  two  affections  may  be 
quite  similar  in  appearance,  although  the  papules  of  eczema  are  always  of  a  brighter  red  hue, 
and  usually  more  or  less  excoriated.  The  concomitant  sjTiiptoms  of  the  syphilitic  eruption 
will  usually  decide  the  diagnosis. 

The  vesicidar  form  of  eczema,  when  at  its  height,  resembles  the  dermatitis  which  results 
from  ivy  poisoning  and  the  inunction  of  strong  mercurial  and  other  vesicating  ointments. 
It  differs  from  these  in  its  tendency  to  occasion  a  decided  infiltration  of  the  skin  and  a  moist 
"weeping"  surface.  This  condition,  which  is  the  most  tj-pical  phase  of  eczema,  could  not 
possibly  be  confounded  with  any  other  affection,  unless  it  be  intertrigo,  in  which  the  moist- 
ure of  the  opposing  surfaces  of  skin  is  chiefly  sweat,  and  devoid  of  the  sticky  character  and 
tendency  to  stiffen  the  linen,  which  is  the  essential  feature  of  the  eczematous  discharge. 

The  pustular  form  of  eczema  may  be  mistaken  for  sycosis,  porrigo  or  favus.  Between 
eczema  of  the  beard  and  sycosis  a  difference  exists  which  is  not  admitted  by  all  ^vl•iters.  The 
inflammatory  process  in  the  latter  affection  is  deep-seated  and  the  pus  which  forms  in  and 
around  the  base  of  the  follicles,  loosens  the  hair  and  appears  at  the  opening  of  the  follicles 
in  the  form  of  minute  pustules,  through  each  of  which  a  hair  passes.  In  eczema  of  the  beard 
there  is  a  more  uniform  redness  and  swelling  of  the  skin  and  the  hairs  are  not  loosened.  Por- 
rigo (or  impetigo  contagiosa)  differs  from  pustular  eczema  in  the  size  of  the  lesions  and  the

character  of  the  crusts  formed ;  while  the  latter  are  usually  numerous,  small  and  thickly 
crowded  and  form  a  large,  irn-egular  dirty  yellow  or  even  brownish  crust,  the  lesions  of  the 
former  affection  are  larger,  circular  and  discrete,  and  form  a  lightly  adherent  straw-colored 
crust  beneath  which  there  is  a  pinkish  patch  of  skin  with  no  moisture.  When  pustular  eczema 
has  formed  a  thick  yellowish  crust  upon  the  scalp  it  maj"  bear  a  resemblance  to  the  mortar- 
like crust  of  favus,  but  the  hair  is  wholly  unaffected  in  the  former  case  and  there  are  no 
bright  yellow  cup-shaped  crusts  at  the  mouths  of  the  hair  follicles  as  are  commonly  seen  in 
cases  of  favus. 

The  squamous  form  of  eczema  is  most  apt  to  be  confounded  with  psoriasis  or  dermatitis 
exfoliativa  when  severe  and  general,  and  mth  the  squamous  syi)liilide  when  it  is  limited  to 
the  palm.  Eczema  and  psoriasis  may  be  undistinguishable  as  far  as  the  lesion  of  the  skin  is 
concerned,  but  the  shape  of  the  patches,  the  general  configuration  of  the  einiption  and  the 
history  of  the  case  serve  as  a  basis  for  diagnosis.  While  in  eczema  the  patches  are  rarely  cir- 
cular, and  usually  shade  off  into  healthy  skin  at  the  margin,  the  scaly  spots  of  psoriasis 
or  larger  confluent  patches  are  either  circular  or  if  confluent  retain  the  sharply-defined  border 
of  the  original  discs.  While  eczema  is  often  unsymmetrical  and  especially  liable  to  afl'tct 
the  flexures  of  the  joints,  the  genital  region  and  other  parts  where  the  skin  is  thin,  psoria- 
sis is  usually  remarkably  symmetrical,  and  prone  to  affect  chiefly  the  extensor  aspect  of  the 
extremities.  The  squamous  form  of  eczema  is  subject  to  occasional  exacerbations,  at  which 
time  a  moist  surface  is  very  apt  to  develop.  Psoriasis  presents  the  peculiarity  of  increasing- 
in  intensity  at  certain  seasons  of  the  year,  and  nearly  or  qaite  disappearing  at  regular  periods, 
usually  through  the  summer  mouths. 

A  general  eczema  bears  a  strong  resemblance  to  dermatitis  exfoliativa,  but  it  does  not,  as. 
a  rule,  involve  every  inch  of  skin,  as  is  the  case  with  the  latter  affection.  Moreover,  it  pro- 
duces a  marked  thickening  of  the  skin  which  is  notably  absent  in  dermatitis  exfoliativa.  In 
general  eczema  there  are  usually  moist  patches  which  are  characteristic,  but  even  in  exfolia- 
tive dermatitis  these  may  be  develojjed  as  a  secondary  eruption  about  the  flexures  of  thv, 
joints. 

Eczema,  when  limited  to  the  palms  and  soles,  is  extremely  difficult  in  many  cases  to  dis- 
tinguish from  a  squamous  syphilide.  If  the  eruption  is  symmetrical  and  irregular  in  outline 
and  without  a  well-defined  border,  the  probabilities  are  that  it  is  eczema.  On  the  other  hand 
if  but  one  palm  or  sole  is  affected  and  if  the  eruption  assumes  a  circular  or  semi-circular  form, 
is  serpiginous  in  character,  with  an  abrupt,  elevated  margin  and  a  comparatively  smooth 
centre,  it  is  usually  safe  to  consider  it  as  of  syphilitic  origin.  The  itching  and  cracking 
which  are  supposed  to  be  characteristic  of  eczema  are  symptoms  which  may  likewise  be 
present  in  the  chronic  squamous  syphilide  of  the  palm. 

Treatment.  Among  the  laity  there  exist  many  absurd  and  erroneous  notions  regarding 
eczema,  and  chief  of  these  is  the  very  common  impression  that  certain  chronic  cases  ai"^ 
incurable.  It  is  true  that  many  cases  tax  the  skill  and  patience  of  even  the  physician  who 
has  had  a  large  experience  in  the  treatment  of  skin  diseases,  but  it  may  be  positively  stated 

(57) 


BTSEASES  OF  THE  SEIN.—INFLAMMA  TOR  Y. 

that  every  case  of  eczema  is  amenable  to  proper  treatment.  The  great  majority  of  cases,  in- 
cluding those  which  involve  a  large  extent  of  cutaneous  surface,  and  which  are  apparently  of 
the  worst  t\-pe,  Avill  yield  at  once  if  judicious  methods  are  instituted.  These  measures  are 
necessarily  various  and  miist  be  selected  in  accordance  with  the  varying  etiology  of  different 
cases.  While  constitutional  invigomting  treatment  is  of  the  greatest  importance  in  one  case, 
the  next  will  require  nothing  beyond  a  careful  selection  of  local  applications.  Most  cases, 
however,  require  a  combination  of  both  constitutional  and  local  treatment  to  effect  a  radical 
and  speedy  cure. 

The  constitiitional  treatment  of  eczema  may  be  summed  up  in  the  advice  to  improve  the 
patient' s  health  in  every  possible  way.  There  is  no  routine  plan  to  pursue,  or  at  least  there 
should  be  none.  Give  tonics  when  needed,  regulate  the  diet,  improve  the  digestion,  when 
impaired,  relieve  existing  constipation,  if  possible,  and  rectify  all  errors  of  hygiene. 

Of  tonics,  a  plentiful  supply  of  fresh  air,  and  where  it  is  feasible,  a  change  of  air  and 
scene,  is  one  of  the  most  reliable  in  the  treatment  of  eczema,  as  of  numerous  other  ills.  Iron, 
quinine,  cod-liver  oil,  and  other  remedies  may  be  called  for  by  the  condition  of  the  patient, 
but  these  have  little  or  no  direct  effect  upon  the  diseased  skin.  The  diet  of  the  patient  is  an 
important  matter  to  consider,  although  eczema  is  less  dependent  upon  gastric  and  intestinal 
derangement  than  some  of  the  other  inflammatory  affections,  e.  g.,  acne  and  urticaria.  In 
many  cases  the  diet  must  be  restricted  in  amount,  or  an  increased  amount  of  exercise  strongly 
insisted  upon  in  order  to  ensure  the  perfect  digestion  of  the  food  w^hich  is  taken  into  the 
stomach.  The  amount  of  nitrogenous  food  consumed  by  many  patients  suffering  from  ec- 
zema is  greatly  in  excess  of  their  needs  and  should  be  lessened.  In  hot  weather  I  have  gen- 
erally found  it  advisable  to  prohibit  entirely  the  use  of  meat.  "When,  as  is  frequently  the  case, 
there  exists  an  aversion  to  fat  meat,  often  the  result  of  whim  or  education  rather  than  natural 
taste,  the  patient  should  be  encoiiraged  to  take  plenty  of  cream,  butter,  or  fat  in  some  form. 
Cod-liver  oil,  especially  in  strumous  children,  is  frequently  of  the  greatest  benefit. 

There  is  no  specific  treatment  in  eczema,  no  single  remedy  of  pre-eminent  value.  The 
administration  of  arsenic,  as  a  first  and  last  resort  in  every  case,  is  a  prevalent  custom  whirh 
I  must  emphatically  condemn.  Arsenic  is  a  valuable  remedy  in  pemphigus  and  psoriasis,  and 
indeed  in  some  cases  of  eczema  ;  but  of  so  little  value  is  it  in  the  latter  disease,  as  compared 
with  other  remedies,  that  I  very  rarely  find  any  occasion  to  prescribe  it. 

The  value  of  purgation  in  eczema  is  debated.  While  not  accepting  the  old  idea  of  a 
maieries  morbi  being  carried  out  of  the  system  in  this  way,  I  must  say  that  clinical  experi- 
ence demonstrates  that  in  many  cases  of  both  acute  and  chronic  eczema,  particularly  of  the 
erj-thematous  variety,  the  administration  of  purgatives  for  a  few  days  wUl  be  followed  by  an 
immediate  and  permanent  improvement,  and  this,  too,  in  cases  which  are  not  being  treated 
locally,  or  in  which  local  applications  have  had  comparatively  little  effect.  Diuretics,  by 
.stimulating  the  kidneys,  and  thus  relieving  the  skin  of  some  of  its  functional  duties,  certainly 
])roducc  a  most  decided  improvement  in  many  cases  of  eczema,  and  are  almost  indispensable 
\vhen  treating  patients  with  gouty  or  rheumatic  tendencies.     Our  natural  mineral  waters  have

ECZEMA. 

a  \ery  beneficial  effect  in  most  cases  of  chronic  and  obstinate  eczema,  and  the  Ballston  waters 
which  contain  a  large  amoimt  of  lithia,  I  can  especially  recommend.     Of  the  alkaline  salts, 

either  the  acetate  or  the  citrate  of  potassium,  in  one  or  two  gram  doses  (gr.  xv. xxx.),  will  be 

found  of  great  service.     This  should  always  be  taken  well  diluted,   and  either  a  half  horn- 
before  or  an  hour  after  each  meal. 

Gelseminum,  cypripedium  and  the  bromides  may  often  be  given  with  good  effect,  especi- 
ally at  night,  to  lessen  the  intense  prui-itus  from  which  eczematous  patients  suffer. 

The  success  of  local  treatment  in  eczema  depends  upon  its  adaptation  to  the  case  in  hand. 
Innumerable  are  the  remedies  which  have  been  recommended,  but  without  a  knowledo-e  of 
the  principles  which  govern  its  use,  no  remedy  can  be  of  much  service.  I  ^^-ill  venture  to 
assert,  that  so  far  as  local  applications  are  concerned,  the  great  majority  of  cases  of  eczema 
can  be  successfully  treated  \\-ith  two  simple  ones,  which  are  always  on  hand,  or  very  easily 
obtained,  viz.,  sweet  oil  and  soft  soap.  Of  course,  I  do  not  advise  the  reader  to  use  these, 
since  there  are  various  emollient  applications  superior  to  the  former,  and  stimidatino-  reme- 
dies which  may  ad\  antageously  supplant  the  latter ;  but  I  hold  that  it  is  far  better  to  luiow 
how  and  when  to  use  even  the  two  remedies  mentioned,  which  typify  two  opposite  modes  of 
treatment,  than  to  have  a  well-stocked  drug  store  at  command,  and  to  use  its  contents  with- 
out definite  purpose.  AVhat  mil  a  bland  oil  or  an  emollient  ointment  accomplish  in  the 
treatment  of  eczema  ?  It  wiU  soften  and  remove  any  crusts  which  may  be  present,  it  will 
soothe  the  inflamed  parts,  and  alleviate  the  itching,  and  it  will  protect  the  denuded  corium 
from  the  desiccating  influence  of  +he  air  and  the  irritating  action  of  water,  and  thus  allow  the 
growth  of  a  new  and  healthy  epidermis.  In  the  acute  eczema  of  infancy,  and  in  the  acute 
form  of  the  disease,  at  whatever  age  it  may  be  met  with,  it  matters  little  what  oil  or  ointment 
or  lotion  be  employed  so  long  as  it  is  the  most  soothing  application  that  can  be  made.  "What 
wUl  soap  accomplish  in  the  treatment  of  eczema  \  It  will  free  the  surface  of  the  skin  from  a 
mass  of  dead  epidermis,  it  ^^^.ll  give  exit  to  confined  serum,  it  ^vill  stimulate  the  circulation 
of  blood  in  the  diseased  skin,  and  thereby  promote  the  absorption  of  the  infiltrated  products 
of  inflammation.  In  chronic  cases,  where  there  is  thickening  and  induration  of  the  skin, 
with  ])ersistent  d-:^squamation  and  annoying  pruritus,  cases  in  which  emollient  applications 
are  utterly  inefficacious,  soap  frictions  will  change  the  character  of  the  eczema  from  a  chronic 
to  a  sub-acute  form,  a  condition  tending  naturally  to  recovery.  In  fact,  as  in  quinine  in  the 
treatment  of  malaria,  so  is  sapo  viridis,  or  ordinary  soft  soap,  in  the  treatment  of  chronic 
eczema. 

The  widespread  popularity  of  green  soap  is  due  solely  to  its  therapeutic  efficacy,  and 
exists  despite  numerous  objections  to  it  which  might  be  raised.  Though  purporting  to  be 
composed  of  potash  and  olive-oU,  it  is  commonly  made,  as  many  are  aware,  of  hemp-seed, 
rape-seed,  whale  and  other  animal  oils  not  always  free  from  rancidity.  Hence  the  offensive 
odor  of  the  green  soap  which  is  commonly  obtained  in  the  market.  The  saponification  of  the 
soap  is  not  always  perfect,  and  it  usually  presents  a  streaky,  variegated  appearance.     Its 

(59) 


DISEASES  OF  TEE  SKIN.— INFLAMMATORY. 

green  color  is  artificial  and  due  to  the  presence  of  indigo  and  other  dye-stuflfs.  It  tends  to 
harden  on  exposure  to  the  air,  and  finally  its  alkalinity  varies  to  such  a  degree  as  to  render 
its  effects  more  or  less  uncertain. 

Some  years  ago  a  friend  suggested  to  me  the  use  of  a  substitute  in  the  shape  of  a  soft 
olive  soap  used  extensively  in  the  manufacture  of  silli  and  other  delicate  fabrics.  This  1  have 
tried  and  found  to  be  a  similar,  though  far  more  elegant  article  than  the  ordinary  sapo  viridis. 
It  is  made  from  cold-pressed  olive-oil,  and  owes  its  green  color  entirely  to  the  chloro- 
phyl  of  the  olive.  As  manufactured  by  Bagoe  &  Co.,  of  New  York,  it  is  of  unvarying 
alkalinity,  wholly  free  from  unpleasant  odor,  homogeneous  and,  unlike  the  common  green 
tsoap,  it  gives  a  perfectly  clear  solution  with  strong  or  dilute  alcohol.  I  have  found  it  advan- 
tageous to  add  to  the  soap  a  small  percentage  of  glycerine,  which,  whUe  counterbalancing  the 
natural  loss  of  free  water,  renders  it  a  most  agreeable  preparation. 

The  most  common  mistake  made  in  the  local  treatment  of  eczema  is  in  the  application  of 
over-stimulating  ointments  and  iiTitating  lotions  to  parts  which  demand  the  most  soothing 
measures,  and  in  the  application  on  the  other  hand,  of  the  oxide  of  zinc,  or  some  other 
slightly  astringent  ointment,  to  cases  in  which  nothing  short  of  soap  frictions  or  some  equally 
harsh  remedy  will  prove  of  the  slightest  benefit.  At  the  risk  of  repetition,  let  me  say  again, 
that  the  grade  of  inflammation  determines  the  selection  of  a  soothing  or  a  stimulating  plan 
of  treatment.  If  the  affected  part  is  swoUen  and  hot,  pouring  forth  a  profuse  discharge,  and 
accompanied  by  an  intense,  burning  pruritus,  the  local  applications  cannot  be  of  too  soothing 
a  nature.  If  the  skin  is  dry,  thickened,  indurated  and  scaly,  the  local  treatment  can  hardly 
be  too  severe.  Where  the  disease  is  extensive,  as  in  Eczema  universale,  it  is  generally  neces- 
sary to  vary  the  character  of  the  treatment  upon  different  portions  of  the  body. 

Such,  briefly  stated,  are  the  principles  which  govern  the  local  treatment  of  eczema.  As, 
in  general  treatment,  the  habit  and  idiosyncracies  of  the  patient  must  be  borne  in  mind,  so 
in  local  treatment  must  the  character  of  the  lesions  be  studied  and  routine  practice  avoided. 
The  reader  must  cast  aside  the  vulgar  notion  that  a  wonderful  therapeutic  power  dwells  in 
the  remedy  which  is  used,  and  learn  that  success  in  treatment  is  wholly  due  to  the  skillful 
adaptation  of  remedies  to  the  requirements  of  each  case. 

In  acute  eczema  the  pain  and  swelling  which  are  sometimes  present  at  the  very  outset  of 
the  attack,  may  be  relieved  by  the  application  of  a  cooling  and  sedative  lotion,  such  as  the 
common  mixture  of  lead  water  and  laudanum.  Lime  water,  "  black  wash,"  and  the  diluted 
fluid  extract  of  grindelia  robusta,  or  hamamelis,  have  been  highly  recommended  for  this  con- 
dition of  the  skin.  With  the  occurrence  of  exudation  the  application  of  a  soothing  and 
protective  ointment  is  preferable.  The  diachylon  ointment  recommended  by  Hebra,  and 
extensively  used  in  Germany,  is  valuable  if  properly  made,  but  the  zinc  oxide  ointment  of 
Wilson  is  more  commonly  used  in  England  and  this  countrj-,  and  on  the  whole  is  to  be  pre 
ferred.     A  better  application  than  either,  according  to  my  experience,  is  one  recommended 

by  Lassar,  and  composed  as  follows :

This  is  often  the  only  local  application  which  is  needed  in  a  case  of  eczema  when  seen 
at  an  early  stage,  but  when  the  acute  inflammation  has  subsided,  and  especially  when  the 
affection  has  reached  its  third  or  scaling  stage,  the  return  to  a  normal  condition  of  the  skin 
will  be  hastened  by  the  addition  of  live  per  cent,  of  oil  of  cade  to  the  formula  given  above. 

In  chronic  cases  of  eczema  equal  parts  of  tar  and  alcohol  may  be  well  rubbed  into  the 
affected  skin  by  means  of  a  sponge  or  stiff  shaving  brush,  and  if  this  does  not  prove  too 
stimulating  for  the  condition  of  the  skin  which  is  present,  it  wall  certainly  tend  to  allay  the 
itching,  and  lessen  the  thickening  which  has  taken  place  as  a  resiilt  of  the  prolonged  intiam- 
mation.  Chrysarobin  is  a  most  valuable  remedy  in  many  cases  of  chronic  eczema,  and  may 
be  applied  in  the  form  of  a  pigment  or  varnish,  prepared  by  suspending  the  powder  in  coUo- 
dium  or  the  solution  of  gutta  percha,  or  in  the  form  of  the  following  ointment : 

51     Chrysarobin,        ....         5  parts. 
Salicylic  acid,  .         .         .         .     6       " 

Petrolatum  to  .         .         .        50       " 

M. 
It  should  be  borne  in  mind  that  this  ointment  will  stain  and  ruin  the  bed  linen  and 
underclothing  of  the  patient  while  it  is  curing  the  eczema,  and  the  patient  should  therefore 
be  made  acquainted  with  this  fact.  Eecently  a  novel  and  efficacious  method  of  treating 
eczema  by  means  of  medicated  glycerine-jelly  has  been  highly  recommended  by  Pick,  Unna, 
Morrow  and  others,  and  bids  fair  to  become  generally  popular.  This  jelly  is  prepared  by 
boiling  together  one  part  of  gelatine  and  three  or  four  of  glycerine  until  they  form  a  trans- 
lucent mass.  To  this  any  medicament,  such  as  oxide  of  zinc  or  chrysarobin  can  be  added. 
When  ready  to  be  used  a  sufficient  quantity  of  the  soft  tenaceous  mass  can  be  melted  in  a 
cup,  and  the  warm  liquid  jelly  painted  over  the  affected  skin  by  means  of  a  stiff  brush.  It 
dries  quickly  and  forms  a  thin,  flexible,  artificial  cuticle. 

The  question  as  to  whether  the  rapid  cure  of  eczema  may  prove  prejudicial  to  the  patient 
has  been  freely  discussed.  The  experience  of  nearly  all  dermatologists  answers  this  with  an 
emphatic  negative.  No  peccant  matter  is  ever  eliminated  from  the  system  in  the  foi-m  of  an 
eczematous  discharge,  and  under  no  cirumstances  can  the  disease  be  regarded  as  salutary.  It 
is  true  that  the  eruption,  in  rare  instances,  seems  to  alternate  with  affections  of  the  respiratory 
apparatus  ;  but  this  merely  shows  that  inflammation  of  the  skin  is  not  apt  to  co-exist  with 
inflammation  of  an  internal  organ.  If  a  child  imder  treatment  for  eczema  is  exposed  to  cold 
or  injured  by  a  faU,  and  contracts  pneumonia  or  meningitis,  the  eruption  naturally  subsides, 
in  consequence  of   the  determination    of   blood  to  the  lungs  or  brain.      The  rapid  cure  of 

(61) 


DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

eczema,  instead  of  being  the  cause,  is  rather  the  result  of  the  internal  phlegmasia.  In  this 
■waj'  an  eruption  maj-  be  said  to  be  dl■a^vn  in,  but  it  is  impossible  for  local  treatment  to  drive 
it  in.  I  have  no  doubt  but  that  in  some  cases  of  infantile  eczema  harm  has  resulted  from 
the  application  of  strong  mercurial  ointments  to  a  large  extent  of  skin  ;  but  it  has  been  the 
mercurj-  and  not  the  disease  which  has  been  driven  in.  Death  or  severe  illness,  from  what 
ever  cause,  is  preceded  by  the  subsidence  of  any  eczematous  discharge  which  has  pre-existed, 
and  Ulogical  friends  of  the  patient  are  not  only  liable,  but  often  disposed,  to  mistake  the 
cause  for  the  eifect. 

ECZEMA  INFANTILE.  The  occurrence  of  eczema  in  infants  and  children  under  five 
years  of  age  is  so  common,  its  clinical  appearance  so  marked  and  its  treatment  so  peculiar, 
that  for  practical  purposes  eczema  of  infants  might  be  considered  as  a  distinct  affection  from 
eczema  of  adult  life.  It  occurs  among  the  rich  as  well  as  among  the  poor,  although  less 
likely  to  assume  an  aggravated  form  when  the  child  is  properly  cared  for.  It  often  com- 
mences immediately  after  birth,  or  when  the  infant  is  but  a  few  week  old,  persisting,  if  not 
properly  treated,  for  several  years.  It  runs  a  somewhat  irregular  course,  appearing  better 
and  worse  from  week  to  week,  the  occasional  exacerbations  of  the  disease  being  usually 
unaccountable.  The  disease  is  a  most  annoying  one  in  all  cases,  not  only  to  the  little  sufferer, 
but  to  the  mother  or  nurse  who  has  charge  of  the  case,  Avhose  sleep  is  so  frequently  broken  by 
the  child's  distress. 

Eczema  of  infants  is  most  common  tipcn  the  scalp  and  face,  and  this  locality  is  generally 
affected  when  eczema  is  present.  In  addition  there  may  be  patches  of  the  eruption  upon  the 
tnmk  and  extremities,  involving  a  considerable  portion  of  the  integument.  Upon  the  scalp 
the  eruption  usually  affects  the  anterior  portion,  except  when  pediculi  are  the  cause  of  the 
trouble,  in  which  case  the  UTitation  and  scratching  almost  invariably  produces  an  eruption 
upon  the  occiput.  The  seborrhoea,  which  so  frequently  forms  a  dirty,  gi-easy  and  persistent 
coating  upon  the  cro^vn  of  the  infant's  head,  is  very  frequently  the  starting  point  of  an 
eczema  which  may  occupy  the  same  location  or  spread  down  upon  the  ears  and  simultaneously 
affect  the  cheeks.  When  the  hair  is  scant  the  eruption  upon  the  scalp  presents  a  red  and 
crusted  or  scaly  appeaiance,  quite  similar  to  the  patches  upon  the  face  ;  but  in  older  children, 
whose  hail-  is  thick,  the  chief  feature  of  the  eruption  is  the  mucilaginous  discharge,  which 
occui-s  here  and  there  as  portions  of  the  scalp  become  torn  by  scratching  or  irritated  in  any 
way,  and  which  tends  to  dry  and  produce  an  appearance  as  though  a  little  gum  arable  had 
been  poured  upon  the  head  and  allowed  to  dry  on  the  hair.  This  characteristic  gumming 
together  of  bundles  of  hair  will  often  enable  one  by  the  sense  of  touch  to  make  as  positive 
a  diagnosis  of  eczema  as  could  be  made  after  the  most  careful  examination  of  the  scalp. 

Upon  the  face  the  eruption,  when  at  its  height,  is  generally  moist  and  covered  with  a 
crust  which  results  from  the  drying  of  the  characteristic  gummy  discharge.  This  alone  pro- 
duces a  thin  crust  like  a  coat  of  varnish  which  cracks  whenever  the  skin  becomes  more 
inflamed  and  swollen,  and  the  discharge  oozing  through  these  cracks  in  the  epidermis  and 
drying  gradually  causes  a  thickening  and  a  very  irregular  surface  of  the  crust.     Such  a  crust 

(62) 


ECZEMA. 

is  u.^uaUy  quite  adherent,  unless  cast  off  by  a  swelling  of  the  skin  and  a  greatly  increased 
discharge,  in  which  case  a  red,  raw  and  angry  looking  patch  is  exposed,  which  becomes 
quickly  covered  by  a  new  crust.  Where  pus  is  mingled  Avith  the  discharge  from  the  skin,  as 
is  usually  the  case  in  certain  forms  of  infantile  eczema,  the  crust  is  always  thicker,  more 
friable,  and  of  a  dirty  yellowish  hue.  Such  a  crust  may  remain  upon  the  skin  until  the 
inllammatory  condition  beneath  has  in  great  part  subsided  and  then  be  cast  off,  leaving  a  dry, 
reddened  and  scaling  surface.  In  many  cases  cf  eczema  of  the  face  in  infants  the  cheeks  are 
merely  reddened  and  thickened,  but  not  exhibiting  any  discharge  excppt  at  numerous  points 
where  the  skin  has  been  excoriated  by  the  nails  and  covered  with  dark  blood  crusts. 

In  the  etiology  of  infantile  eczema  there  are  certain  special  factors  to  be  considered  in 
addition  to  those  which  have  already  been  mentioned.  An  inherited,  or  at  least  a  congenital 
tendency  to  eczematous  inflammation  cannot  be  denied  in  many  cases,  and  such  are  often 
difficult  to  cure  as  the  active  cause  cannot  be  demonstrated.  In  many  cases  an  improper  diet 
is  a  potent  factor  in  the  production  of  the  eczema  which  will  yield  with  surprising  rapidity 
when  careful  attention  is  paid  to  this  point.  Teething,  to  which  the  eruption  is  so  frequently 
attributed  by  those  having  care  of  infants,  has  nothing  to  do  with  the  causation  of  infantu'e 
eczema.  Nor  has  vaccination  any  etiological  importance,  in  spite  of  the  firm  belief  of  many 
fond  parents  to  the  contrary. 

The  frequent  washing  of  an  infant  or  child  affected  with  eczema,  is  one  of  the  most  com- 
mon of  means  unconsciously  employed  by  the  mother  or  nurse  to  aggravate  the  existino- 
inflammatory  condition.  Many  cases  can  be  cm-ed  by  doing  nothing  more  than  insistino-  upon 
total  abstinence  from  the  use  of  soap  and  water. 

The  diagnosis  of  infantile  eczema  is  always  easy  when  the  characteristic  exudation  is 
present.  When  the  eruption  is  dry,  scaly  or  crusted  mistakes  sometimes  occur.  At  an  early 
age  the  outbreak  of  inherited  syphilis  might  be  confounded  with  it,  but  it  should  be  remem. 
bered  that  the  lesions  in  such  a  case  are  especially  liable  to  accumulate  about  the  mucous 
orifices,  are  circular  in  form  when  diy,  and  do  not  present  any  symptom  of  severe  itchrno-  even 
when  moist.  Scabies  in  young  children  is  liable  to  be  considered  as  a  papular  eczema,  and 
the  lesions  indeed  are  indistinguishable,  but  in  the  latter  affection  the  history  of  conta"-ion 
where  the  children  sleeping  together  are  all  affected,  the  limitation  of  the  eruption  to  the 
trunk  and  extremities,  and  the  discovery  of  the  burrow  of  the  acarus  upon  the  soft  skin  be- 
tween the  fingers  or  elsewhere  will  reveal  the  parasitic  origin  of  the  eruption. 

Urticaria  occuring  in  children  is  frequently  called  eczema.  An  itching  and  excoriated 
skin  is  to  be  found  in  either  affection,  but  patches  of  eruption  are  only  met  with  in  the  latter, 
while  the  history  which  is  given  of  the  sudden  outbreak  and  speedy  disappearance  of  red  or 
white  lumps  poiats  clearly  to  the  former  affection. 

Treatment.  In  caring  for  a  case  of  infantile  eczema,  it  is  essential  that  the  physician 
should  not  only  understand  what  to  advise,  but  he  should  also  see  that  his  advice  is  followed. 
Otherwise  his  sldll  and  advice  are  of  no  avail.  All  directions  given  must  be  explicit,  and  it  is 
usually  advisable  to  have  them  repeated  by  the  mother  or  nurse,  in  order  to  make  sure  of  their 

(63) 


DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

being  undfci'scood.  In  very  many  cases  it  is  the  neglect  of  certain  directions,  apparently 
of  minor  importance,  rather  than  any  peculiar  obstinacy  of  the  eruption,  which  renders  the 
treatment  tedious  and  sometimes  futUe. 

The  diet  of  the  infant  is  usually  the  fii'st  point  to  be  considered,  with  a  view  to  removing 
the  cause  of  the  eruption.  In  the  case  of  infants  at  the  breast,  it  is  a  very  common  custom 
of  mothers  to  nurse  the  child  whenever  it  cries;  and  as  the  crjnng  usually  results  from  a  dis- 
ordered digestion,  the  practice  of  giving  the  breast  every  half  hour  only  adds  to  the  child's 
discomfort  and  aggravates  the  eruption.  If  the  mother's  milk  is  insufficient  in  quantity,  or 
not  of  proper  quality,  it  is  much  better  to  wean  the  infant  at  once,  except  in  mid-summer, 
than  to  attempt  to  supply  the  deficiency  of  nutrition  by  a  partial  resort  to  artificial  feeding 
After  weaning  it  is  a  common  custom,  especially  among  the  poorer  classes,  to  give  the  child 
everything  which  is  on  the  table,  including  tea,  coffee,  picldes,  pastry,  &c.,  the  impropriety 
of  which  must  be  duly  impressed  upon  the  mind  of  the  infant's  nurse  or  mother.  Even 
among  the  more  intelligent  classes,  the  eczematous  chUd,  whose  appetite  is  usually  good,  is 
too  often  allowed  to  eat  at  irregular  intervals ;  and  at  my  college  clinic  I  have  sometimes 
taken  a  number  of  eczematous  infants  before  the  class,  each  with  an  apple,  a  cracker  or  a 
piece  of  candy  or  sugar  in  one  or  both  hands.  This  constant  feeding  between  meals  is  a  fre- 
quent source  of  indigestion  in  young  children,  and  always  tends  to  aggravate  an  already 
existing  eczema.  A  strict  injunction  to  allow  the  child  no  solid  food,  except  at  its  meals,  of 
which  it  may  have  four  daily,  will  often  produce  a  decided  improvement  in  the  character  of 
the  eruption.  The  bowels  should  be  regulated  in  many  cases,  and  when,  as  often  happens, 
the  stools  are  found  to  be  unusually  light  colored,  a  mild  calomel  purge  once  or  twice  a  week, 
as  recommended  by  Wilson,  wiU  prove  of  the  greatest  benefit.  The  alkaline  diuretics  which 
are  so  frequently  called  for  in  the  treatment  of  eczema  of  adults,  may  be  given  for  a  few 
days  to  children  whose  urine  is  acid  and  irritating  to  the  skin  of  the  genital  region,  but  a 
solution  of  magnesia  or  lime  water  will  usually  have  a  better  effect  and  can  be  continued  for 
a  longer  time.  Of  other  internal  medicines,  arsenic  and  viola  tricolor  have  been  especially 
recommended,  but  my  experience  has  led  me  to  rely  mainly,  if  not  wholly,  upon  hygienic 
and  dietetic  measures  combined  with  local  applications. 

The  value  of  fresh  air  as  a  curative  agent  in  infantile  eczema  is  rarely  appreciated  as  it 
should  be.  Its  immediate  soothing  effect  ui^on  an  eczematous  infant  who  has  persistently 
refused  to  sleep,  or  to  refrain  from  scratching  for  more  than  a  half  hour  at  a  time,  is  often  as 
surprising  as  it  is  delightful.  It  is  sometimes  difficult  to  have  a  child  taken  out  of  doors  on 
account  of  the  foolish  notion  that  it  is  too  hot  or  too  cold,  too  windy  or  too  damp,  and  often 
the  parents  object  to  having  the  little  sufferer  appear  in  public  with  its  head  and  face  band- 
aged ;  but  when  removed  from  a  hot  and  close  atmosphere  to  the  pm-e  open  air  for  a  half  hour 
to  an  hour  or  two  daily,  according  to  the  weather,  the  beneficial  effect  upon  the  eruption  will 
soon  be  noticeable. 

In  the  use  of  local  applications  to  the  eczema  of  infants,  patience,  perseverance,  and 
above  all,  intelligence,  are  required.     The  main  object  should  be  to  soothe  and  protect  the

skin.     For  this  purpose  the  application  which  I  have  formd  to  be  the  very  best  of  many 
which  I  have  employed,  is  the  following  : 

'^     Salicylic  acid,  ...  2  parts. 

Subnitrate  of  bismuth,      .        .30      " 

Com  starch,  ...        20      "  ' 

Ointment  of  Rosewater  to  100      "  * 

M. 
This  should  be  spread  thickly  on  pieces  of  stout  muslin  and  carefully  applied,  so  that 
every  portion  of  inflamed  and  moist  skin  should  be  smoothly  covered.  Where  there  is  merely 
a  dry  squamous  form  of  the  afl:ection  present,  it  can  be  rubbed  over  the  surface  of  the  skin 
by  mean.'?  of  the  finger.  The  application  being  pasty  rather  than  oily  in  character,  is  more 
adhesive  than  the  ordinary  ointments  which  have  been  recommended,  and  is  not  so  easily 
rubbed  off.  Indeed  it  maj-  be  repeatedly  applied  until  a  thick,  white  and  rather  dry  coating 
forms  upon  the  surface  of  the  skin,  which  lessens  the  itching  and  the  redness,  and  allows  a 
healthy  epidermis  to  form. 

Upon  the  scalp  this  ointment  or  paste  is  not  to  be  used  on  account  of  its  tendency  to  mat 
the  hairs  together.  Upon  this  region  an  oily  application  is  preferable.  If  thick  crusts  are 
present  they  should  be  removed  by  a  poultice  or  the  application  of  an  oiled  sUk  skuU-cap. 
When  removed,  the  following  may  be  rubbed  into  the  scalp  night  and  morning : 

9     Oil  of  Cade, 

Almond  oil,  equal  parts. 
M. 

The  oiled  silk  cap  may  be  continued  to  be  worn,  and  will  not  only  protect  the  bed-linen 
fi-om  becoming  soiled  by  the  tar,  but  will  itself  have  a  good  effect  upon  the  eczematous  scalp. 

ECZEMA  OF  THE  SCALP.  In  adults  eczema  of  the  scalp  is  by  no  means  as  common 
as  among  young  children.  Xor  is  it  as  common  as  eczema  of  other  portions  of  the  body.  It 
is  often  persistent,  however,  and  demands  the  most  skillful  treatment.  Its  course  is  gener- 
ally a  chronic  one,  and  although  there  may  be  at  times  a  moist  discharge  at  one  or  more 
points  the  eruption  is  commonly  of  the  squamoiis  type.  The  crown  of  the  head  is  its  favorite 
seat,  and  in  some  cases  the  ears  are  simultaneously  affected.  The  affection  begins  insidiously, 
and  considerable  itching  is  often  endured  before  the  patient  discovers  the  presence  of  one  or 
more  scaly  patches.  Examination  now  shows  that  the  affected  jDortions  of  the  scalp  are  red- 
dened and  considerably  thickened.  The  affection  is  subject  to  occasional  exacerbations,  and 
may  subside  spontaneously  to  such  a  degree  that  for  a  while  the  patient  is  comparatively  free 
from  annoyance.  The  growth  of  the  hair  is  never  affected  in  any  appreciable  degree  by  the 
presence  of  the  eruption. 

The  cause  of  eczema  of  the  scalp  is  not  always  apparent,  but  even  the  patient  ^^-ill  usually 
discover  that  it  tends  to  become  aggravated  by  all  attempts  to  get  the  scalp  clean  througli 
frequent  washing  oi  digging  at  the  scales  with  a  comb. 

(65) 


DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

The  affections  with  which  eczema  of  the  scalp  is  apt  to  be  confounded  are  seborrhoea 
psoriasis,  and  in  certain  instances  a  tubercular  syphilide  limited  to  this  portion  of  the  body. 
In  sebon-hoea  capitis,  as  has  already  been  stated,  there  is  but  slight  if  any  redness  of  the  scalp, 
and  the  scales  are  soft  and  unctuous  in  character.  While  with  eczema  capitis  the  ears  are  apt 
to  be  involved,  with  seborrhoea  capitis  the  nose  is  more  apt  to  be  simultaneously  aifected. 
Psoriatic  patches  upon  the  scalp  bear  a  very  strong  resemblance  to  eczema,  but  they  are  usu- 
ally circular  and  marginate  in  form  and  rarely  exist  without  patches  of  psoriasis  upon  other 
portions  of  the  body,  which  serve  at  once  as  a  key  to  their  diagnosis.  A  tubercular  syphilide 
affecting  the  scalp  likewise  possesses  this  abrupt  margin.  But  it  is  unaccompanied  by  pruri- 
tus, and  the  nodules  seen  upon  a  careful  examination  of  the  scalp  tend  to  softening  and 
ulceration,  which  in  time  results  in  cicatrization  and  partial  baldness. 

Treatment.  One  of  the  very  best  applications  for  the  cure  of  eczema  of  the  scalp  is  the 
oil  of  cade.  It  may  be  applied  of  full  strength,  even  when  there  is  a  slight  amount  of  moist- 
ure present,  for  the  scalp  appears  to  tolerate  the  stimulant  action  of  this  remedy  when  a  simi- 
lar moist  eczema  of  other  parts  would  only  be  aggi*avated  by  it.  As  the  odor  and  color  of 
this  application  render  its  use  objectionable  in  many  cases,  in  private  practice  a  less  efficient 
remedy  must  often  be  employed.  When  there  is  but  slight  thickening  of  the  skin  a  little 
ammoniated  mercury  ointment  may  be  rubbed  into  the  scalp  with  the  finger  every  night  and 
morning,  and  when  the  itching  is  very  annojdng  an  ointment  of  naphthol  of  from  three  to 
five  per  cent,  may  be  advantageously  employed.  It  is  hardly  necessary  to  say  that  a  thin 
layer  of  ointment  smeared  over  a  thick  crust  will  have  no  effect  upon  the  diseased  skin  be- 
neath. Cutting  the  hair  short  facilitates  treatment ;  but  in  the  case  of  women  and  young  girls 
who  are  reluctant  to  be  cropped,  it  is  never  absolutely  necessary. 

ECZEMA  OF  THE  FACE.  An  acute  attack  of  eczema  may  occur  upon  the  forehead 
and  cheeks,  assume  the  vesicular  form  and  be  accompanied  by  considerable  burning  pain  and 
swelling.  This  usually  runs  its  course  in  from  one  to  two  weeks,  although  where  an  eczema- 
tous  tendency  is  present  the  eruption  may  assume  the  chronic  form.  For  this  condition  a 
dusting  powder  of  bismuth  and  corn  starch  or  a  lead  lotion  is  advisable  during  the  inflam- 
matory stage,  and  a  bland  ointment  to  be  applied  when  the  skin  begins  to  desquamate. 

Eczema  of  the  face,  however,  usually  assumes  a  chronic  erythematous  form  in  adults,  and 
is  most  apt  to  affect  the  eyelids  and  neighboring  parts.  The  eruption  begins  with  a  dry, 
harsh  and  intensely  pruritic  condition  of  the  skin  which  gi-adually  becomes  thickened  and 
covered  with,  a  mealy  desquamation.  The  skin  presents  a  pinkish  or  light-red  hue  and  there 
is  rarely  any  moisture  of  the  surface  from  beginning  to  end.  The  natural  furi'ows  become 
deepened,  and  the  itching  is  of  such  a  character  as  to  render  this  eruption  one  of  the  m  ost 
annoying  that  could  be  imagined,  especially  when  the  patient  is  of  a  highly  nervous  tem- 
perament. 

In  appearance,  erji;hematous  eczema  of  the  infra-orbital  region  may  bear  a  close  resem- 
blance to  rosacea  at  first  glance  ;  but  while  the  hyperemia  is  passive  and  the  skin  is  cool  in 
I  he  latter  affection,  the  skin  is  actively  congested  and  elevated  in  temperature  in  the  former.

ECZEMA. 

It  can  be  readily  distinguished  from  erythematous  lupus,  which  often  presents  a  similar  hue 
and  slight  amount  of  desquamation,  by  the  absence  of  the  marginate  border  Avhich  is  alwaya 
present  in  the  case  of  lupus.

ive functions,  and  perhaps  by  mild  purgatives  continued  for  several  days,  a  lotion  of  hama- 
melis  may  be  kept  applied  to  the  affected  skin  by  means  of  saturated  linen  cloths.  This  -Ail] 
give  temporary  relief,  though  it  may  have  no  curative  effect.  A  mildly  stimulating  ointment 
is  now  advisable  ;  and  the  following  is  one  which  has  jdelded  excellent  results  in  my  liands ;

ECZEMA  OF  THE  BEARD.  The  bearded  portion  of  the  face  is  the  seat  of  several 
skin  affections,  chief  of  which  are  eczema,  sycosis  and  trichophji:osis.  These  affections,  when 
attacking  the  beard,  present  no  important  features  which  are  not  present  when  they  occur 
upon  the  scalp  or  elsewhere.  Eczema  of  the  beard,  though  naturally  occurring  only  in  adult 
males,  tends  to  assume  a  severe  grade  of  inflammation,  but  differs  in  no  essential  regard  from 
eczema  of  the  scalp.  Sycosis  is  an  affection  which  generally  attacks  the  beard,  but  in  rare 
instances  it  occurs  on  hairy  parts  elsewhere,  and  presents  the  characteristic  features  of  the 
disease,  viz.,  suppurating  nodules,  developing  about  the  roots  of  the  hairs.  Trichophytosis, 
or  "ring- worm"  of  the  beard,  has,  in  the  great  majority  of  cases,  the  same  features  as  when 
met  with  upon  the  scalp  and  non-hairy  parts,  and  does  not  deserve  a  different  name.  Indeed, 
much  confusion  has  been  introduced  into  dermatology  by  the  application  of  different  names 
to  the  same  disease  occurring  on  different  portions  of  the  body. 

Eczema  of  the  beard  is  characterized  by  the  symptoms  of  eczema  in  general,  redness, 
burning  or  itching,  exudation,  with  a  tendency  to  the  formation  of  crusts,  and  finally,  thick- 
ening of  the  skin  and  desquamation.  Some  writers  claim  that  a  pustular  eczema  of  the  beard, 
which  of  all  the  forms  of  eczema  bears  the  closest  resemblance  to  sycosis,  can  be  distinguished 
from  the  latter  by  its  extending  beyond  the  hairy  parts,  upon  the  cheeks  and  neck,  whereas 
sycosis  is  strictly  limited  to  the  hairy  parts.  This  point  is  not  always  to  be  relied  upon.  In 
a  large  number  of  cases,  the  eczematous  nature  of  the  eruption  is  clearly  sho\vn  by  its 
occurrence  upon  those  favorite  localities,  the  ear  and  eyelids,  but  its  tendency  to  attack  and 
confine  itself,  like  sycosis,  to  the  hairy  parts,  is  shown  by  its  presence  in  the  pubic  region, 
and  its  conspicuous  absence  beneath  the  oomers  of  the  mouth,  where  the  growth  of  the  beard 
has  not  begun. 

The  first  step  to  take  in  the  treatment  of  eczema  of  the  bearded  portion  of  the  face  is  to 
dispose  of  the  beard.  This  may  be  clipped  very  closely  mth  fine  scissors,  shaved,  or  pulled 
out,  as  the  necessities  of  the  case  demand.  When  the  eruption  is  crusted,  or  the  skin  acutely 
inflamed,  and  exuding  freely,  shaving  is  for  the  time  almost  impossible.  The  hairs  should  be 
cut  as  short  as  possible  with  scissors,  when,  by  a  poultice  or  repeated  inunction  of  oil,  the 

(67) 


DISEASES  OF  TEE  SKIN.— INFLAMMATORY. 

crusts  can  be  removed.  If  now  the  skin  is  tender,  and  shaving  proves  to  be  a  painful  opera- 
tion, it  is  -well  to  continue  the  use  of  the  scissors  in  preference  to  the  razor.  In  the  majority 
of  cases,  however,  shaving  can  and  should  be  performed  at  least  thrice  weekly,  while  the  or- 
dinary treatment  for  eczema  is  can-ied  out.  When  the  affected  part  is  hot,  swollen,  and  dis- 
charging serum,  I  have  seen  excellent  results  follow  moderate  purgation  kept  up  for  two  or 
three  days,  combined  with  hot  fomentations,  or  the  application  of  the  zinc  oxide  ointment 
spread  on  soft  rags,  and  held  in  place  by  a  bandage.  An  infusion  of  senna  or  viola  tricolor, 
or  the  compound  jalap  powder  may  be  used  as  a  purgative.  When  the  acute  inflammation 
has  subsided  under  the  iafluence  of  emollient  applications  and  due  attention  to  the  patient' s 
general  health,  and  the  eruption  has  assumed  the  character  of  a  dry,  reddened  and  scaly 
patch,  the  officinal  ointment  of  sulphur  or  of  the  nitrate  of  mercury  may  be  used,  diluted 
with  from  three  to  five  parts  of  cold  cream.  When  the  morbid  process  shows  a  tendency  to 
extend  from  the  surface  to  the  deeper  portion  of  the  hair  follicles,  the  skin  usually  assumes 
a  liunpy  appearance  resembling  sycosis,  and  pustules  develop  around  the  hairs.  In  such  a 
case,  the  treatment  already  mentioned  is  of  but  little  benefit,  and  epilation  is  called  for.  The 
hairs  are  usually  firm,  and  consequently  extracted  with  pain.  A  small  drop  of  blood  occa- 
sionally follows  the  epilation  of  certain  hairs,  but  this  only  acts  as  an  antiphlogistic,  and  the 
improvement  within  twenty-four  hours  is  often  as  surprising  as  it  is  pleasing.  To  aUay  the 
pain  I  have  in  some  cases  held  a  piece  of  ice  in  contact  with  the  skin  for  a  few  minutes  before 
extracting  the  hairs.  When  the  inflammation  has  attacked  the  deeper  parts,  the  hairs  are 
loosened,  come  out  with  gentle  traction,  the  root  sheaths  being  bathed  in  pus.  In  such  cases 
the  excessive  suppuration  is  apt  to  destroy  the  foUicles,  and  lead  to  permanent  baldness  of 
the  part. 

ECZEMA  OF  THE  EARS.  "While  in  children  eczema  is  very  frequently  observed  be- 
hind and  around  the  ears,  among  adults  the  disease  is  more  liable  to  affect  the  auricle  itself, 
and  the  external  auditory  meatus.  The  affection  is  usually  a  chronic  one.  although  at  times 
an  exacerbation  occurs,  and  the  skin  becomes  the  seat  of  a  moist  discharge.  When  the  dis- 
ease has  persisted  for  months  or  years,  as  is  sometimes  the  case,  the  auricle  becomes  swollen, 
indurated,  and  scaly.  Its  natural  pliability  is  completely  lost,  so  that  the  patient  is  unable 
to  rest  the  head  at  night  except  upon  the  occiput,  and  even  then  a  painful  fissure  is  very  apt 
to  form  in  the  post  auricular  furrow. 

The  diagnosis  of  eczema  of  this  region  is  very  simple  in  the  majority  of  cases.  Erysipelas 
and  erythematous  lupus  can  be  distinguished  by  the  febrile  condition  accompanying  the 
former  disease,  and  the  marginate  character  of  the  patches  and  the  absence  of  itching  which 
characterize  the  latter  affection.  Psoriasis  sometimes  occurs  in  the  form  of  a  scaly  jiatch  be- 
hind the  ear  and  extending  upon  the  auricle,  but  it  is  never  limited  to  this  region,  as  may  be 
the  case  with  eczema,  and  the  presence  of  psoriatic  patches  elsewhere  will  settle  the  diagnosis. 

Treatment.  Chronic  eczema  of  the  auricle  is  generally  an  obstinate  affection,  and  yields 
reluctantly  to  the  most  judicious  treatment.  To  lessen  the  infiltration  of  the  skin,  which 
should  be  our  main  object,  a  stimulating  application  is  required.     An  ointment  containing  tar

naplhol  or  ammoniated  mercury  fulfils  this  indication,  while  keeping  the  scales  softened  au>t 
removed  and  protecting  the  skin  from  the  irritating  influence  of  the  air.  A  pasty  ointment 
which  will  adhere  to  the  skin  is  preferable  to  a  greasy  ointment  which  will  soak  into  the 
clothes  upon  which  it  is  applied,  and  the  following  will  be  found  of  service :

When  eczema  affects  the  external  auditory  canal  there  is  often  but  a  slight  redness  and 
scaliness  to  be  seen,  but  considerable  annoyance  is  experienced  by  the  patient.  The  constant 
digging  at  the  ears  with  the  finger,  a  pin,  or  some  other  instrument,  to  which  the  patient  i-e- 
sorts  for  the  temporary  relief  of  the  itching,  only  aggravates  the  trouble,  until  in  time  such  a 
thickening  of  the  membrane  and  resulting  desquamation  is  produced  that  the  canal  is  ]iar- 
tially  occluded  and  slight  deafness  is  occasioned.  A  purulent  discharge  is  sometimes  present, 
and  the  obstinacy  of  the  affection  under  such  circumstances,  a  fact  noted  by  most  aurists, 
may  be  due  in  gi-eat  part  to  frequent  syringing  of  the  canal  with  soap  and  water.  As  the 
frequent  application  of  water  is  usually  harmful  to  eczema  of  any  part  of  the  body,  it  is  ad- 
visable to  direct  the  patient  to  abstain  from  its  use  in  cleaning  the  auditory  canal.  The  scales 
which  accumulate  rapidly  must  of  coarse  be  removed,  but  this  can  be  done  by  the  use  of  a 
large  camel's  hair  pencil  dipped  in  oil  or  in  oxide  of  zinc  ointment  made  thin  by  the  addition 
of  glycerine.  When  the  canal  is  clear  and  the  discharge  has  ceased  the  oil  of  cade  may  be 
applied  readily  by  means  of  the  brush,  and  usually  with  good  effect  in  lessening  the  annojdng 
pruritus  and  restoring  the  skin  to  its  healthy  condition.  When  the  grade  of  inflammation  is 
extremely  chronic  and  there  is  much  infiltration  of  the  skin,  extending  even  to  the  membrana- 
tympani,  the  application  of  a  strong  solution  of  nitrate  of  silver  has  been  strongly  recom- 
mended. In  my  experience  the  use  of  a  two  per  cent,  ointment  of  chrysarobin  has  been  pro- 
ductive of  the  best  results. 

ECZEMA  OF  THE  HANDS.  Although  eczema  may  attack  either  the  palmar  or  the 
dorsal  surface  of  the  hands,  it  rarely  occurs  in  a  marked  degree  upon  both  at  the  same  time. 
One  hand  only  may  be  affected,  although  the  disease  is  commonly  found  on  both,  and  is 
sometimes  quite  symmetrical.  On  the  back  of  the  hand,  eczema  is  more  apt  to  be  of  internal 
origin,  and  to  co-exist  with  patches  on  the  arm  or  elsewhere.  When  of  long  standing  it  may 
be  papular  or  squamous,  but  it  usually  assumes  the  ichorous  form.  On  the  palm,  eczema 
differs  in  many  respects  from  the  disease  as  it  occurs  elsewhere,  and  demands  a  peculiar  mode 
of  treatment.  As  met  with  in  practice  it  is  usually  dry,  and  characterized  by  homy  scales, 
and  by  deep,  painful  fissures  occurring  in  the  lines  of  flexion.  Sometimes  the  whole  palm  is 
affected.  More  frequently  the  disease  occupies  but  a  portion,  and  appears  as  a  single  diffused 
patch  or  a  number  of  isolated  scaly  patches  of  a  more  or  less  circular  form.     Eczema  of  the 

(69) 


DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

palm  is  usually  chronic  (in  one  sense  of  tlie  term)  from  the  verj'  outset.  It  begins  at  one  or 
more  points  with  redness  and  itching,  and  after  much  gentle  scratching  or  rubbing  with  the 
hand  it  develops  into  a  somewhat  thickened  and  scaly  patch.  This  increases  in  size  by  peri- 
pheral extension,  or  creeps  over  the  palm  with  a  circumscribed  and  curving  border,  very  much 
like  a  squamous  syphilide.  There  is  a  wide  variation  in  the  appearance  of  different  cases. 
Upon  a  soft-skinned  palm,  the  redness,  infiltration  and  desquamation  of  typical  eczema  are 
seen,  while  in  another  case  nothing  is  apparent  but  whitish  patches  of  hornj^  epidermis,  which 
the  patient  is  constantly  picking  or  digging  with  the  finger-nails  of  the  other  hand.  "Where 
much  infiammation  is  present  of  an  acute  grade,  the  palms  become  swollen,  and  numerous 
fissures  result  from  flexion  and  extension  of  the  hands,  until  the  latter  become  too  painful  to 
be  used,  and  are  held  by  the  patient  like  claws,  in  a  rigid  and  semi-flexed  position.  In  old 
cases,  where  the  outer  layers  of  epidermis  have  been  gradually''  removed,  the  skin  of  the 
palms  is  notably  reddened,  feels  harsh  and  dry,  though  quite  smooth,  and  the  natural  lines 
and  f un-ows  are  greatly  exaggerated.  When  the  fingers  in  such  a  case  are  forcibly  extended 
the  blanching  of  the  palm,  which  occurs  to  a  slight  degree  in  a  healthy  hand,  is  well  marked 
and  characteristic. 

The  diagnosis  of  eczema  of  the  hands  is  usually  simple.  Palmar  eczema,  however,  may 
bear  such  a  strong  resemblance  to  scaling  syphilitic  patches  that  experienced  dermatologists 
are  often  unable  to  make  a  positive  diagnosis  from  a  mere  study  of  the  lesions.  According 
to  text-books,  eczema  presents  irregular  patches,  covering  perhaps  the  whole  palm  and  itching 
severely,  while  syphilis  is  characterized  by  smaller  circular  patches,  with  more  infiltration  of 
the  skin,  a  circumscribed  border,  and  an  absence  of  itching.  But  there  are  very  many  excep- 
tions to  this  rule.  Eczema  may  occur  in  a  form  of  small  circular  patches  and  in  the  center  of 
the  palm,  may  have  a  well-defined  border  and  spi'ead  over  the  palm  in  a  serpiginous  manner, 
while  a  palmar  syj^hiloderm  may  itch  and  crack  and  be  aggravated  by  iDutting  the  hands  in 
water,  and,  in  short,  appear  exactly  like  an  eczema.  I  know  of  but  one  infallible  rule  to 
apply.  If  a  number  of  small  scaly  spots  are  arranged  in  a  semicircular  or  horse-shoe  form, 
•with  an  inclosed  area  of  healthy  skin,  or  if  a  spreading  circular  patch  exhibits  an  infiltrated 
margin  and  a  healthy  or  healing  center,  the  patch  is  of  syphilitic  origin.  In  a  doubtful  case 
the  history  of  the  patient  is  of  little  value,  as  the  palmar  syphiloderm,  liable  to  be  con- 
founded with  eczema,  is  a  late  manifestation  of  the  disease,  and  so  many  syi^hilitic  persons, 
particularly  females,  are  unaware  of  ever  having  contracted  the  disease.  The  scaling  papules, 
accompanying  or  following  the  early  secondary  eruption,  ought  never  to  be  mistaken.  Even 
with  a  clear  history  of  sj-philis,  eczema  may  occur  as  an  independent  affection.  "  Psoriasis  " 
is  a  term  applied  by  many  to  every  scaly  palmar  patch,  irrespective  of  its  etiology,  but  among 
dermatologists  the  term  "syphilitic  psoriasis"'  is  rapidlj^  becoming  obsolete.  True  psoriasis 
is  of  so  rare  occurrence  upon  the  palms  that  it  is  not  likely  to  occasion  an  error  in  diagnosis 
in  many  cases,  and  as  it  is  very  rarely  if  ever  limited  to  the  palms,  the  presence  of  the  char- 
acteristic white  scaly  discs  upon  other  portions  of  the  body  ought  to  prevent  its  being  con- 
founded with  eczema  of  the  palm. 

(70) 


ECZEMA. 

The  local  treatment  of  eczema  occurring  on  the  backs  of  the  hands  requires  no  special 
directions.  Soap  frictions  are  useful  in  the  papular  form,  accompanied  wdth  induration  of 
the  skin,  and  even  in  the  case  of  moist  patches,  soap,  though  a  harsh  remedy,  may  be  used 
once  or  rwioi^  to  remove  the  dried  exudation  and  dead  epidermis  in  order  to  give  a  free  exit 
to  the  confined  serum.  Thf>  diachylon  ointment  may  then  be  spread  thickly  on  pieces  of  soft 
cloth,  and  kept  constantly  applied  to  the  moist,  reddened  surface.  The  affected  fingers  may 
be  bandaged  separately  and  tightly,  and  the  hands  must  be  kept  out  of  water  until  a  new 
epidermis  has  formed  and  there  are  no  more  fine  beads  of  exuding  serum. 

Eczema  of  the  palm  requires  a  method  of  treatment  quite  different  from  that  of  eczema 
elsewhere.  The  thickened  epidermis  must  be  removed,  the  painful  cracks  healed,  and  the 
infiltration  of  the  corium  absorbed.  The  skin  must  then  be  kept  in  a  soft,  pliable  state,  until 
the  redness  has  in  i  great  measure  faded  and  there  is  little  tendency  to  itching  and  scaling. 
Though  the  occasional  dipping  of  the  hands  in  water  is  harmful,  there  is  scarcely  a  bet- 
ter nil  xle  of  lessening  the  intiammation,  and  at  the  same  time  macerating  the  epidermis  than 
by  ordering  the  patient  to  place  the  palms  in  a  shallow  vessel  containing  a  little  more  than 
enough  water  to  cover  the  bottom.  The  water  should  be  as  hot  as  can  be  borne,  and  the  palms 
kept  in  it  for  at  least  fifteen  minutes  at  a  time.  "When  there  are  horny  patches,  unaffected 
by  the  water,  glacial  acetic  acid,  or  liquor  potassse  applied  on  a  glass  rod  will  be  found  to 
soften  them  quickly.  These  strong  applications  must  be  handled  with  care,  lest  severe  pain 
be  caused  by  their  getting  into  the  cracks.  But  the  cracks  are  merely  the  result  of  the 
thickened  and  indurated  epidermis,  and  it  is  iiseless  to  heal  them  and  have  them  break 
open  again.  If  their  ciush,  viz.,  the  thickened  epidermis,  be  removed,  they  will  heal  of 
themselves  and  remain  healed.  Rubber  gloves  worn  constantly  (with  the  rubber  side  next 
to  the  skin)  act  beneficially  in  most  chronic  and  obstinate  cases.  After  the  thickened  epider- 
mis has  been  removed  and  the  cracks  healed,  the  palms  may  remain  for  a  long  time  reddened, 
dry  and  harsh,  \vith  a  constant  tendency  to  become  worse  again.  An  ointment  containing 
ten  per  cent,  of  oil  of  cade  in  vaseline  does  well  in  such  cases,  but  success  \vill  depend  less 
upon  local  measures  than  upon  tht  internal  treatment  adapted  to  eczematous  cases  in  general 
and  to  this  patient  in  particular. 

ECZEMA  OF  THE  FEET.  Most  of  what  has  been  said  of  eczema  of  the  hands  will 
apply  to  the  disease  as  it  appears  upon  the  feet.  Here  it  may  exist  alone  or  it  may  co-exist 
with  eczema  of  the  hands.  If  severe  it  usually  interferes  with  locomotion.  Between  and 
around  the  toes  the  eruption  is  apt  to  assume  an  acute  form,  and  the  toes  must  be  bandaged 
separately  like  the  fingers,  or  kept  apart  from  one  another  by  the  intei-position  of  absorbent 
cotton.  A  honiy  condition  of  the  soles  can  be  advantageously  treated  by  the  repeated  appli- 
cation of  the  following  lotion  :

DISEASES  OF  THE  SKIN:— INFLAMMATORY. 

ECZEMA  OF  THE  AISTJS  AND  GEISTTTAL  REGIOjST.  The  anus,  perinc-pum.  vulva, 
penis  and  scrotiun  are  often  the  seat  of  eczema,  and  though  the  affection  in  this  region  is 
usnally  quite  limited  in  extent  it  is  capable  of  producing  the  greatest  amount  of  annoyance 
and  even  distress.  In  many  cases  there  is  simply  intense  pruritus  with  very  little  redness 
and  thickening  of  the  affected  skin.  In  other  cases  there  is  to  be  found  a  decided  infiltra- 
tion of  the  skin  with  more  or  less  scaling  and  a  marked  tendency  to  the  production  of  fissures 
and  excoriations  Finally  there  are  cases  in  which  the  vulva  of  the  female  and  the  glands  and 
under  surface  of  the  penis  and  the  sides  of  the  scrotum  in  the  male  are  entirely  denuded  of 
epidermis  and  exquisitely  tender.  In  these  cases  the  sufferings  of  the  patient  are  almost 
intolerable.  Locomotion  is  difficult,  refreshing  sleep  is  unattainable  and  daily  existence  is 
fraught  Avith  misery. 

Treatment.  Success  in  the  treatment  of  eczema  of  the  anus  and  genitals  usually  de- 
pends upon  the  abiUty  of  the  physician  to  discover  and  remove  the  cause  of  the  eruption  or 
the  conditions  which  tend  to  aggravate  it.  Local  treatment  is  always  valuable  as  a  means  of 
palliating  the  symptoms,  but  it  rarely  proves  curative,  and  the  common  mistake  should  be 
avoided  of  depending  wholly  upon  external  treatment. 

In  eczema  of  the  anus  a  disordered  digestion  is  almost  invariably  at  the  root  of  the 
trouble ;  and  attention  to  diet  is  worth  more  than  all  the  ointments  or  lotions  ever  recom- 
mended. The  patient  is  usually  constipated,  although  he  may  assert  that  his  bowels  are  per- 
fectly regular,  and,  iadeed,  as  a  result  of  training,  they  may  move  once  a  day.  A  tendency 
to  hemorrhoids  is  a  usual  concomitant  of  the  itching,  and  with  this  occurs  the  frequent  dull- 
ness or  headache  indicative  of  obstructed  portal  circulation.  The  patient  is  generally  of  se- 
dentary habits,  and,  having  a  good  appetite,  is  disposed  to  eat  a  great  deal  more  than  he  can 
digest.  The  first  step  in  treatment  then  is  to  restrict  his  diet  or  to  increase  his  amount  of 
daily  exercise,  or,  if  possible,  to  do  both.  It  is  usually  much  easier  for  the  physician  to  les- 
sen the  food  than  to  increase  the  exercise  of  the  average  patient ;  and  as  there  is  no  particular 
kind  of  food  to  which  the  pruritus  or  eczema  of  the  anus  can  be  attributed,  I  have  followed 
the  plan  of  prescribing  but  one  meal  daily,  at  which  the  patient  can  eat  whatever  he  likes 
and  as  much  as  he  likes.  In  place  of  the  other  two  customary  meals  the  patient  may  be  al- 
lowed a  glass  of  milk,  if  this  does  not  produce  a  coated  tongue  and  increase  the  constipation, 
or,  what  is  usually  better  for  him,  a  cup  or  two  of  hot  water  with  one  or  two  graham  crackers. 
This  plan  of  dieting  gives  the  stomach  and  other  digestive  organs  the  rest  which  they  usually 
need,  and  in  obstinate  itching  of  the  anus  mil  often  render  the  use  of  local  applications  quite 
unnecessary.  When,  however,  there  is  much  thickening  of  the  sldn  about  the  anus,  some 
soothing  local  remedy  may  be  simultaneously  employed.  Innumerable  have  been  the  appli- 
cations recommended  for  this  purpose,  but  the  one  which  has  seemed  to  me  to  do  the  most 
good  in  the  largest  number  of  cases  is  the  officinal  chlorofonn  liniment.  In  many  patients 
of  a  nervous  temperament  the  use  of  tobacco,  even  in  moderation,  \vill  serve  to  aggravate  the 
affection,  and  hence  in  every  obstinate  case,  it  is  well  to  proscribe  this,  together  with  indul- 
gence in  tea,  coffee  and  alcoholic  stimulants.

DERMATITIS    EXFOLIATIVA.

ECZEMA. 

In  eczema  of  the  scrotum  a  similar  plan  of  diet  will  prove  beneficial,  though  perhaps  to 
a  less  extent  than  in  eczema  of  the  anus.  Local  treatment  will  naturally  vary  in  accordance 
with  the  grade  of  inflammation  and  condition  of  the  skin.  When  there  is  a  moist  surface  or 
numerous  excoriations  the  most  cooling  application  is  the  salicylic  and  bismuth  ointment 
already  mentioned  in  connection  with  infantile  eczema.  When  the  skin  is  thickened,  dry 
and  harsh  a  napthol  ointment  of  from  three  to  five  per  cent,  strength  Avill  lessen  the  itching 
and  gradually  soften  the  skin.  In  very  chronic  cases  the  compound  chrysarobin  pigment 
may  be  used.  This  occasions  considerable  smarting  for  five  or  ten  minutes  after  its  applica- 
tion, but  it  vdll  usually  secure  to  the  patient  a  quiet  sleep  at  night,  and  if  frequently  applied 
will  soon  restore  the  skin  to  its  normal  condition. 

In  severe  eczema  of  the  vulva  or  penis  an  examination  of  the  urine  should  be  made  from 
time  to  time,  as  a  diabetic  condition  is  frequently  the  underlying  cause  of  the  eruption,  which 
will  continue  to  resist  all  treatment  until  by  a  judicious  modification  of  the  diet  the  sxagar 
disappears  or  is  reduced  to  a  minimum  in  the  urine. 

ECZEMA  OF  THE  LEGS.  Eczema  of  the  lower  portion  of  the  legs  is  common  in  mid- 
dle life  and  old  age.  It  is  usually  of  long  standing,  and  requires  stimulation.  When  the 
eruption  is  dry,  as  in  the  erythematous  and  papular  forms,  the  skin  is  simply  reddened, 
harsh,  itchy,  and  more  or  less  excoriated.  Daily  frictions  with  green  soap  will  soften  the 
skin  and  relieve  the  itching.  After  using  the  soap,  the  legs  should  be  carefully  dried,  and  a 
slightly  astringent  ointment  applied.  In  the  squamous  form,  the  soap  frictions  wiU  remove 
the  scales  and  often  cause  an  exuding  surface  to  appear.  This  temporary  aggravation,  how- 
ever, by  stimulating  the  flow  of  the  blood  through  the  part  and  promoting  absorption,  will 
speedily  reduce  the  thickening  of  the  skin.  In  the  ichorous  form  of  eczema  (weU  shown  in 
the  plate  of  Eczema  cruris),  and  in  the  squamous  form  when  there  is  any  tendency  to  a  dis- 
charge, the  application  of  vulcanized  rubber  cloth  is  one  of  the  best  plans  of  treatment.  It 
cleanses  and  cools  the  surface,  promotes  a  copious  flow  of  serum,  and  quickly  lessens  pain  and 
swelling.  The  cloth  should  envelop  the  leg  with  the  rubber  surface  next  to  the  skin,  and  be 
held  in  position  by  a  roller  bandage.  When  the  ankle  is  affected,  the  cloth  may  be  gored  or 
cut  so  as  to  fit  smoothly.  The  rubber  bandages,  to  be  described  later  in  the  treatment  of 
varicose  conditions,  are  sometimes  preferable,  though  more  likely  to  irritate  the  healthy  skin. 
When  the  leg  has  returned  to  its  normal  size,  and  the  exudation  has  nearly  ceased,  the  rub- 
ber is  no  longer  of  service,  and  the  cure  may  be  completed  by  applying  the  nitrate  of  mer- 
cury ointmerit,  one  or  two  parts,  to  the  oxide  of  zinc  ointment,  eight  or  nine  parts.  When 
the  skin  is  infiltrated,  itchy  and  scaly,  but  only  to  a  slight  extent,  the  preparations  of  tar 
can  be  advantageously  employed.  Where  there  is  an  exuding  surface  the  use  of  tar  is  contra- 
indicated. 

The  permanent  dilatation  of  veins  to  which  the  term  varicose  is  applied  begins  usually 
in  early  or  middle  life,  and  affects  chiefly  the  internal  saphenous  and  its  branches.  Tho 
enlarged  vein  may  be  simply  distended,  or  it  may  be  hypertrophied,  and  either  form  a  tumor 
by  doubling  on  itself,  or  run  a  serpentine  course  for  a  short  distance.     About  the  ankle  and

DISEASES  OF  THE  SKIN— INFLAMMATORY. 

on  the  dorsa]  surface  of  the  foot,  it  is  common  to  find  the  venous  twigs  dilated,  and  appear- 
ing as  numerous  purplish  blue  dots  or  streaks.  The  cause  of  varicose  veins  is  not  always 
apparent,  although  ill  health,  standing  occupations,  pregnancy,  tight  garters,  etc.,  doubtless 
exert  an  influence  in  their  production.  The  result  of  their  presence,  however,  rather  than 
their  causes,  renders  them  of  importance  from  a  dermatological  standpoint.  In  many 
persons  varicose  veins  of  the  lower  extremities  exist  for  years  without  producing  any  eifect 
upon  the  skin,  or  even  inducing  any  feeling  of  discomfort.  Given,  however,  a  tendency 
to  eczema  in  such  a  case,  and  it  wUl  not  be  long  before  some  external  irritation  will 
provoke  an  eruption  which  will  prove  rebellious  to  ordinary  treatment,  on  account  of  the 
oedema  and  infiltration  of  the  skin,  which  in  time  becomes  associated  mth  varicose  veins 
of  the  leg. 

Treatment.  The  treatment  of  varicose  eczema  involves  the  ordinary  therapeutic  meas- 
ures adapted  to  the  cure  of  the  disease,  with  the  addition  of  a  support  for  the  enlarged  veins. 
So  long  as  the  limb  is  allowed  to  swell  daily  from  pressure  or  a  column  of  blood,  so  long  will 
lotions  and  ointments  fail  to  effect  a  cure.  If  the  limb  cannot  be  maintained  in  a  horizontal 
position  (and  exercise  is  as  desirable  in  many  cases  as  it  is  unavoidable),  some  form  of  bandage 
or  elastic  stocking  is  required.  The  ordinary  roller,  if  smoothly  applied,  answers  a  two-fold 
purpose  in  compressing  the  limb  and  keeping  the  dressings  in  place.  But  rarely  do  we  find 
a  patient  who  can  make  the  reverse  turns  properly,  and  a  bandage  twisted  around  the  leg  and 
drawn  tight  to  keep  it  from  sliding  down  will  do  more  harm  than  good  A  flannel  roller  is 
preferable  to  one  made  of  cotton  cloth,  on  account  of  its  greater  elasticitj^  and  softness,  and 
when  applied  moist  it  will  produce  a  tolerably  firm  compression  of  the  leg.  As  for  the  elas- 
tic stockings  in  the  market  it  may  be  said  that  the  cheap  ones  are  useless,  while  the  good 
ones  are  too  expensive  for  a  large  class  of  patients.  The  rubber  bandage  introduced  by  Dr. 
Martin  has  of  late  become  widely  known  and  deservedly  popular.  It  not  only  supports  the 
dilated  veins  and  thus  tends  to  remove  a  cause  of  the  eruption,  but  by  its  local  action  it  ma- 
cerates the  epidermis,  and  facilitates  the  escape  of  serum  confined  in  the  skin  and  subcuta- 
neous tissue.  By  its  elasticity  it  exerts  a  constant  pressure  on  the  leg,  and  induces  a  rapid 
absorption  of  the  products  of  inflammation.  It  is,  in  fact,  a  happy  combination  of  the  im- 
permeable rubber  dressing  and  the  elastic  stocking.  It  can  be  applied  by  any  patient  of 
average  intelligence,  as  no  reverse  turns  are  needed ;  it  can  be  tightened  or  loosened  with 
ease,  and,  unlike  the  ordinary  roller,  which  speedily  becomes  loose,  it  maintains  its  pressure 
even  when  the  leg  decreases  in  size  by  subsidence  of  the  oedema.  The  rubber  bandage  should 
be  applied  in  the  morning  before  the  patient  gets  out  of  bed.  At  night,  after  its  removal, 
both  leg  and  bandage  should  be  washed  and  carefully  dried.  The  bandage  may  now  be  re- 
applied, or  if  the  infiltration  has  nearly  disappeared,  and  especially  if  the  skin  is  much  irri- 
tated, it  is  better  to  dress  the  leg  with  an  emoUient  ointment  and  to  wait  until  morning  before 
re-applying  the  bandage.  In  cases  where  the  bandage  is  applied  for  an  eczema  of  the  ankle 
or  lower  part  of  the  leg,  the  healthy  skin  above  may  become  irritated.  This  can  be  prevented 
liy  dusting  the  sound  skin  night  and  morning  with  powder  of  starch,  oxide  of  zinc  or  bis-

PITYBIASIS. 

muth,  but  it  indicates  an  eczematons  tendency  on  the  part  of  the  patient  and  suggests  greater 
reliance  on  internal  medication. 


PITYRIASIS. 

Pityriasis  is  a  mild  affection  of  the  skin,  in  which  a  very  slight  redness  and  a  mealy  or 
branny  desquamation  are  the  chief  features.  There  may  be  a  triiling  amount  of  infiltration 
of  the  skin  when  the  affection  is  well  marked,  and  a  sensation  of  heat  or  pruritus  ;  but 
ordinarily  the  skin  is  not  thickened  in  any  noticeable  degree,  and  no  especial  discomfort  is 
experienced.  The  scales  are  small,  white,  not  imbricated,  as  in  psoriasis,  and  very  readily 
removed  by  friction.  When  rubbed  or  washed  away,  they  foi-m  again  very  quickly.  The 
disease  occurs  in  patches  of  variable  size,  the  borders  of  which  shade  off  into  the  surround- 
ing healthy  skin.  It  is  most  frequently  met  with  upon  the  scalp  and  face,  but  may  occur 
upon  the  neck  and  covered  portions  of  the  body.  Upon  the  scalp  it  constitutes  a  dry  form 
of  dandriff  in  which  the  scales  are  not  fatty  in  character,  as  in  seborrhoea  capitis,  but  are 
composed  wholly  of  fine  epidermic  flakes.  It  is  the  kind  of  dandriff  in  which  the  scales  do 
not  adhere  to  the  scalp,  but  fall  copiously  whenever  the  hair  is  brushed,  and  accumulate 
upon  the  shoulders.  It  is  usually  the  result  of  a  pre-existing  erythematous  condition  of  the 
scalp,  is  very  chronic  in  character,  and  usually  indicative  of  a  lowered  vitality  of  the  scalp, 
if  not  a  condition  of  general  nervous  debility.  Care,  anxiety,  or  dissipation  wUl  often  pro- 
duce an  immediate  effect  in  augmenting  the  amount  of  desquamation  and  the  falling  of  the 
hair,  which,  in  time,  becomes  an  inevitable  concomitant  of  dandriff.  The  eye-brows  and 
beard  are  often  simultaneously  affected  with  the  scalp. 

Upon  the  face,  pityriasis  is  most  apt  to  occur  in  the  winter  season,  and  after  exposure 
to  harsh  winds.  Those  subject  to  the  affection  are  usually  found  to  have  a  pretematurally 
dry  skin,  and  in  infants  and  young  children  an  eczematous  tendency  is  commonly  present. 

When  caused  or  aggravated  by  external  influences,  the  eruption  may  only  last  for  a  week 
or  two,  but  in  many  cases  it  is  quite  persistent. 

Diagnosis.  The  diagnosis  of  pityriasis  from  a  mUd  case  of  erythematous  or  squamous 
eczema,  is  not  readily  made,  and  indeed  many  writers  do  not  admit  that  pityriasis  is  a  dis- 
tinct disease.  In  many  cases  pityriasis  gradually  merges  into  eczema,  but  when  there  is 
merely  a  rosy  colored  patch  of  skin,  covered  with  fine  white  scales,  the  clinical  appearance 
is  quite  different  from  eczema,  and  the  infiltration  or  thickening  of  the  skin,  the  cracking  of 
the  epidermis  with  a  tendency  to  moisture,  and  the  annoying  pruritus,  which  are  essential 
elements  of  the  latter  affection,  are  never  met  with  in  the  former. 

Psoriasis  sometimes  appears  in  patches  of  a  pinkish  color,  and  with  very  little  scaling, 
but  in  such  cases  the  marginate  border  of  the  patches,  their  characteristic  localization,  and 
their  symmetrical  development  would  prevent  an  error  in  diagnosis. 

Trichophjiiosis  of  non-hairy  parts  sometimes  presents  an  appearance  very  similar  to  that 
of  pityriasis,  as  far  as  color  and  desquamation  are  concerned,  but  the  outline  of  the  paiches 

(76) 


DISEASES  OF  TEE  SKIN.— INFLAMMATORY. 

is  quite  diflferent  in  the  two  affections.  In  ordinary  pityriasis  the  patches  are  not  usually 
circular,  and  have  no  well  defined  margin,  while  in  ring-worm  these  are  characteristic 
features. 

Seborrhoea  is  the  affection  with  which  pityriasis  is  most  apt  to  be  confounded,  and  as 
has  been  already  stated,  when  these  affections  occur  upon  the  scalp,  a  strict  differential 
diagnosis  cannot  always  be  made.  Upon  non-hairy  parts  the  patches  of  pityriasis  feel  dry 
and  harsh,  while  those  of  seborrhoea  feel  greasy  to  the  touch,  and  may  lea  ve  a  trace  of  oU 
upon  the  finger  which  is  passed  over  the  affected  skin. 

TitEATMENT.  The  iuunction  of  any  fatty  substance  will  suffice  to  cure  many  cases  of 
pityriasis,  but  a  slightly  stimulating  ointment,  such  as  the  following,  wiU  usually  act  more 
rapidly.

In  pityriasis  of  the  face,  the  effect  of  water  frequently  applied,  and  exposure  to  cold 
winds,  are  apt  to  be  as  irritating  as  in  cases  of  eczema.    It  is  therefore  advisable  to  apply 
some  soothing  ointment  or  lotion  immediately  after  washing,  and  always  before  going  into  the 
open  air.    The  following  lotion  will  be  found  of  value  to  prevent  the  skin  from  becoming

DERMATITIS  EXFOLIATIVA. 

Synonym — Pityriasis  rubra. 

Exfoliative  dermatitis  is  a  comprehensive  term  which  is  now  applied  to  certain  rare  cases 

of  skin  disease,  which  are  characterized  by  intense  redness  of  the  skin  and  desquamation  of 
the  epideimis  in  large  flakes.  It  probably  includes  one  or  two  distinct  affections,  but  in  the 
present  state  of  our  knowledge  it  is  hardly  possible  to  separate  them.     While  some  cases

have  appeared  in  an  acute  form,  the  majority  of  those  described  under  the  title  pity liu  si  ■> 
rubra,  or  dermatitis  exfoliativa,  have  been  extremely  clironic  in  their  course,  evincing  a  ten- 
dency to  recurrent  exacerbations  or  relapses,  and  frequently  terminating  in  death  from 
marasmus  or  exhaustion.  The  disease  has  been  limited  in  a  few  cases  to  a  portion  of  the 
body,  but  as  a  rule,  the  hyperaemia  and  exfoliation  are  general,  and  not  the  smallest  portion 
of  skin  remains  unaffected. 

In  those  cases  which  have  been  observed  in  the  incipient  stage  of  the  disease  extensive 
reddened  patches  covered  with  a  fine  desquamation  have  appeared  in  the  axillary  inguinal  and 
popliteal  regions.  These  have  spread  rapidly  until  they  have  invested  the  entire  sui'face  of 
the  skin.  At  this  stage  the  eruption  is  very  striking  in  appearance.  The  skin  is  of  a  rather 
bright  red  color,  with  perhaps  a  duller  or  somewhat  livid  hue  upon  the  extremities,  and  the 
local  temperature  is  elevated.  Pressure  of  the  finger  caused  the  hypersemia  to  disappear, 
leaving  the  skin  of  a  yellowish  tinge,  and  pinching  up  a  fold  between  the  thumb  and  finger 
shows  that  there  is  very  little,  if  indeed  any,  infiltration  and  thickening.  The  desquamation 
which  is  persistent  and  abundant  is  made  up  of  thin  flakes  which  curl  up  at  the  margin, 
while  adherent  in  the  centre  to  the  underlying  skin.  These  flakes  are  usually  of  large  size, 
and  when  forcibly  removed  leave  a  smooth,  glazed,  or  a  slightly  moist  surface. 

The  patient  experiences  a  moderate  amount  of  pruritus,  in  some  cases,  and  invariably 
complains  of  a  sensation  of  chniLness.  This  condition  may  persist  without  any  notable 
change  for  one  or  two  years.  In  time  the  skin  begins  to  appear  tightly  drawn,  as  though  it 
were  too  small  for  the  body.  Fissures  and  ulceration  are  now  liable  to  occur.  The  expres- 
sion of  the  countenance  becomes  greatly  altered  from  the  resulting  ectropion  of  the  lids  and 
lessened  mobUity  of  the  lips,  and  the  fingers  and  larger  joints  are  usually  partially  flexed. 
The  hair  and  nails  lose  their  lustre,  become  friable,  and  are  often  lost.  The  general  health 
fails,  and  without  the  best  of  care  and  nursing,  the  patient  falls  into  a  pitiable  condition. 

Diagnosis.  The  affection  which  bears  the  closest  resemblance  to  exfoliative  dennatitis 
is  a  chronic  universal  eczema  of  an  erythematous  or  squamous  type.  In  this  affection,  how- 
ever, there  is  apt  to  be  considerable  thickening  of  the  skin,  a  most  annoying  jDruritus  and  at 
some  time  and  in  some  locality  a  moist  surface,  ■with  the  peculiar  mucilaginous  character  of 
a  typical  eczematous  discharge.  At  the  same  time,  it  must  be  borne  in  mind  that  in  some 
cases  of  exfoliative  dermatitis  we  may  have  a  slight  thickening  of  the  skin,  more  or  less 
pruritus,  and  a  thin  serous  moisture  of  the  skin  when  the  flakes  of  epidennis  are  removed. 

Psoriasis  universalis  might  be  mistaken  for  exfoliative  dermatitis,  but  the  similarity  is 
by  no  means  so  striking  as  in  the  case  of  eczema.  Psoriasis  rarely,  if  ever,  covers  every  inch 
of  skin,  biit  usually  leaves  some  small  portions  in  a  normal  condition.  It  is  a  pei'fectly  diy 
eruption,  and  is  not  associated  with  any  marked  impaiiment  of  the  general  health.  The 
scales  may  be  thick  and  horny  but  are  never  seen  in  large  papery  flakes,  and  the  eruption, 
however  extensive  or  chronic,  is  always  disposed  to  yield  to  a  judicious  local  treatment. 

Pemphigus  foliaceus  may,  in  certain  cases,  and  at  certain  times,  be  indistinguishabh* 
from  exfoliative  dermatitis.     The  occurrence  of  flattened  and  imperfectly  formed  bullae  i:i

the  former  affection,  is  the  only  distinctive  feature.  The  present  tendency  of  dermatologi- 
cal  writers  is  to  class  these  two  affections  together,  and  I  may  quote  an  opinion  expressed 
nearly  ten  years  ago  in  connection  with  the  report  of  a  case  of  pityriasis  rubra.  (Archives 
of  Dermatology.)  "In  the  extensive  exfoliation  of  cuticle,  in  the  serous  exudation  which 
in  the  one  case  imparts  to  the  skin  a  peculiar  moisture,  and  in  the  other  case  Ufts  the  epi- 
dermis into  bullae,  in  the  marasmus  of  the  latter  stage,  and  in  the  slow  recovery  if  not  the 
fatal  termination  of  either  disease,  we  observe  a  striking  similarity,  and  I  venture  to  say  that 
a  deeper  insight  into  the  etiology  and  nature  of  skin  disease  will  yet  reveal  an  intimate  con- 
nection between  these  two  affections."  Hyde,  who,  describing  pityriasis  rubra  and  pem- 
phigus foliaceus  as  two  forms  of  exfoliative  dermatitis,  writes  as  follows :  "  If  it  be  objected 
that  pityriasis  rubra  and  pemphigus  foliaceus  should  be  disassociated  because  the  former  is  a 
dry  and  non-discharging  disease,  and  the  latter  a  moist  and  exuding  affection,  characterized 
always  at  first  and  often  at  last  by  the  occurrence  of  blebs,  the  answer  is  sufficiently  ami^le. 
The  same  arguments  precisely  which  demonstrate  the  identity  of  erythematous,  papular  and 
vesicular  eczema,  will  Indissolubly  connect  the  two  affections  under  consideration." 

Tkeatment.  Little  can  be  done  in  most  cases  of  exfoliative  dermatitis  which  will  influ- 
ence the  course  of  the  disease.  Arsenic  has  been  thoroughly  tried  and  found  wanting.  Fresh 
air,  nutritious  food  and  tonics  will  prove  of  some  value,  and  the  fi'equent  inunction  of  linsted 
oil  in  large  quantity  will  keep  the  skin  in  a  comparatively  comfortable  condition.  Tilbi/ry 
Fox  was  a  strong  advocate  of  the  value  of  alkaline  diuretics  given  with  a  view  to  relieve  the 
cutaneous  congestion  by  stimulating  the  kidneys  to  increased  action.  In  -one  case,  I  have 
noted  a  remarkably  beneficial  effect  follow  the  administration  of  di'achm  doses  of  acetato  of 
potassium,  three  times  daily.    At  best,  the  prognosis  in  this  affection  is  extremely  grave. 

PSORIASIS. 

Synonyms — Lepra — Alphas — Dry  tetter. 

This  very  common  affection  consists  in  circumscribed  patches  of  red  and  thickened  skin, 
covered  usually  ^vith  whitish  or  yellowish- white  scales.  The  patches  may  be  isolated  or  con- 
fluent. In  the  former  case  they  vary  in  size  from  a  pin-head  to  a  saucer,  and  are  circular  in 
form.  In  the  latter  case  they  give  rise  to  large  irregular  patches,  with  scolloped  borders,  and 
frequently  with  inclosed  areas  of  normal  or  slightly  pigmented  skin.  In  some  cases  the 
entire  body  and  especially  the  trunk  may  be  affected,  and  appear  reddened,  thickened,  and 
more  or  less  scaly.  The  patches  always  begin  in  the  form  of  small  red  papules,  surmounted 
by  a  thin  scale.  These  may  be  scattered  abundantly  over  the  body,  and  show  little  or  no 
tendency  to  increase  in  size  (P.  punctata).  They  are  more  apt,  however,  to  assume  the  size 
of  a  cent  or  quarter-dollar,  and  when  numerous  and  aggregated  they  appear  as  though  a 
handful  of  thin  mortar  had  been  spattered  over  the  skin  (P.  guttata).  In  a  small  number  of 
(^ases  the  patches  are  few  and  large,  and  appear  like  sUver  coins  of  large  size  (P.  nummulata). 
Generally  the  patches  tend  to  coalesce  as  they  increase  in  size,  and  lose  their  circular  outline

PSORIASIS     ANNULATA

(P.  diffusa).  In  nearly  all  cases  the  central  portion  of  the  patch  is  the  first  to  disappear,  and 
in  consequence  scaly  rings  are  produced  (P.  annulata)  and  in  rare  instances  crescentic  and 
seiiaentine  lines  (P.  gyrata).  The  scales  of  psoriasis  are  imbricated,  and  in  most  cases  easily 
removed.  In  appearance  they  have  been  compared  to  sUver  and  to  mother  of  pearl.  Their 
thickness  is  usually  in  proportion  to  the  amount  of  infiltration  of  the  subjacent  sldn.  In 
diffused  patches  they  are  often  branny  in  character,  whUe  in  chronic  cases  they  become  thick 
and  hard,  like  plates  of  armor.  The  extensor  surfaces  of  the  extremities,  the  back  and  the 
scalp,  are  the  favorite  sites  of  the  affection.  Upon  the  elbows  and  knees  and  along  the  fron- 
tal margin  of  the  scalp  it  occurs  with  the  greatest  frequence,  although  it  is  not  invariably 
present  upon  these  parts. 

Of  the  etiology  of  psoriasis  very  little  is  knoAvn.  It  occurs  imder  the  greatest  variety  of 
conditions  and  shows  little  or  no  partiality  for  any  climate,  race,  age  or  sex.  Its  relation- 
ship to  syphilis  and  to  tuberculosis  has  been  claimed  by  some,  but  never  satisfactorily  demon- 
strated. Lang  has  recently  attempted  to  prove  its  parasitic  character.  It  is  not  contao-ious 
but  in  very  many  families  the  hereditary  transmission  of  the  disease  or  of  a  tendency  to  it 
is  quite  manifest.  When  a  tendency  to  psoriasis  exists  clinical  observation  shows  that  preo-- 
nancy,  lactation,  or  whatever  reduces  vitality  tends  to  provoke  the  eruption,  and  even  exter- 
nal irritation  or  injury  to  the  skin  Avill  often  determine  the  localization  of  the  lesions.  WhUe 
some  \vriters  connect  psoriasis  mth  a  dartrous  or  rheumic  diathesis,  others  regard  it  as  a 
purely  local  disease.  The  symmetrical  nature  of  the  eruption  which  is  almost  invariably  one 
of  the  most  striking  features  would  seem  to  indicate  that  the  disease  was  constitutional  and 
either  dependent  upon  some  dyscrasia  or  lesion  of  the  nerve  centres  which  control  the  for- 
mation of  the  homy  stratum  of  the  epidermis.  The  majority  of  psoriatic  patients  seem  aa 
strong  and  hearty  as  the  average  of  mortals,  and  if  not  in  perfect  health,  they  at  least  be- 
lieve themselves  to  be  so. 

Diagnosis.  The  diagnosis  of  psoriasis  is  generally  easy,  especially  in  typical  cases.  It 
must  be  constantly  borne  in  mind,  however,  that  the  eruption  may  be  in  its  declining  stage 
or  modified  by  previous  treatment,  in  which  case  it  differs  greatly  in  appearance  from  the 
eruption  when  seen  at  its  height  and  before  treatment.  If  a  psoriatic  patient  is  stripped  suf- 
ficiently to  reveal  the  greater  portion  of  the  eruption,  a  diagnosis  can  readily  be  made  by 
observing  the  characteristic  configuration  of  the  patches  even  when  viewed  at  a  considerable 
distance.  When  the  eruption  is  seen  in  its  incipient  stage,  and  only  a  few  scaly  points  or 
drops  are  present,  a  diagnosis  can  often  be  arrived  at  by  observing  the  ease  with  which  the 
scale  can  be  removed  by  the  finger  naU,  and  the  bleeding  corium  which  is  exposed  beneath  it. 
Too  much  stress,  however,  is  often  laid  upon  this  point,  as  in  some  cases  of  eczema,  where 
tbe  eruption  is  recent  and  accompanied  by  sUght  scaling  and  little  or- no  infiltration  of  the 
true  skin,  the  finger  naU  may  remove  the  epidermis  as  readily  as  in  psoriasis,  and  a  number 
of  bleeding  points  will  be  seen  springing  from  the  lacerated  papillae.  If  the  condition  of  the 
eruption,  together  with  its  location,  does  not  settle  the  diagnosis,  the  history  of  the  case  will 
generally  furnish  the  necessary  clue.     Its  occurrence  at  certain  seasons  of  the  year,  and  its 

(79) 


DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

partial  or  complete  disappearance  at  others,  its  absolute  and  persistent  dryness,  aud  its  ten- 
dency to  relapse  after  being  apparently  cored,  are  features  of  the  case  which  point  only  to 
psoriasis. 

The  papulo-squamous  syphilide  is  the  one  eruption  above  all  others  which  may  bear  a  close 
resemblance  to  a  typical  psoriasis,  and  in  certain  cases  it  is  very  difficult,  if  not  impossible, 
to  make  a  diagnosis  of  the  eruption  without  taking  into  consideration  the  history  and  con- 
comitant symptoms.  If  the  eruption  is  chronic  and  has  disappeared  and  reappeared  from 
year  to  year  it  is  undoubtedly  psoriatic,  while  on  the  other  hand,  if  it  has  developed  recently 
and  extensively,  and  is  associated  with  other  unmistakeable  symptoms  of  syphilis  in  its 
early  stage,  the  syphilitic  nature  of  the  eruption  is  highly  probable.  It  is  commonly  stated 
that  psoriasis  affects  the  extensor  aspect  of  the  extremities,  while  the  scaling  papular  syphi- 
lide is  seen  chiefly  upon  the  flexor  surface.  Too  much  stress  must  not  be  laid  upon  this 
point,  for  exceptions  to  the  rule  in  either  disease  are  common.  Nor  is  the  presence  or  absence 
of  itching  a  trustworthy  point  of  differential  diagnosis,  for  in  certain  cases  of  psoriasis  there 
may  be  very  little  or  no  itching,  while  in  nearly  aU  squamous  syphilides  the  patient  will  con- 
fess to  a  slight  pruritus  if  questioned  in  regard  to  the  matter. 

The  color  of  the  lesions  in  the  two  diseases  is  practically  the  same  and  is  never  charac- 
teristic. The  scaling  is  usually  more  abundant  upon  the  psoriatic  guttje,  while  the  infiltra- 
tion of  the  skin  is  more  marked  in  the  sj-T^hilitic  lesions. 

Eczema,  in  its  squamous  form  may  be  mistaken  for  psoriasis  when,  as  occasionally  hap- 
pens, it  occurs  in  orbicular  patches  with  a  circumscribed  border.  The  limited  extent  of  the 
eruption,  its  non-symmetrical  location,  together  with  the  pruritus  and  a  tendency  to  become 
moist  and  form  crusts  instead  of  scales  when  the  surface  is  violently  rubbed,  are  points  which 
will  usually  lead  to  a  correct  diagnosis. 

Treatmext.  The  treatment  of  a  case  of  psoriasis  is  simple  as  far  as  regards  the  removal 
of  the  eruption.  It  is  a  much  more  difficult  matter  to  prevent  its  return.  In  nearly  every  case 
there  is  undoubtedly  a  morbid  condition  of  the  economy,  an  ill-defined  something,  deeper 
than  the  scaly  patches.  Some  call  this  the  disease,  and  regard  the  cutaneous  affection  as  a 
mere  symptom.  Others  apply  the  term  psoriasis  solely  to  the  cutaneous  lesions,  and  look  upon 
internal  morbid  conditions  as  predisposing  causes.  The  supporters  of  the  diathetic  nature  of 
psoriasis  assert  that  local  measures  cannot  cure  the  disease,  while  others  claim  that  when  the 
skin  is  restored  to  its  normal  condition  the  disease  is  cured  for  the  time  being,  although  the 
imperfectly  understood  causes  still  existing  may  induce  its  return.  This  is  a  mere  quibble. 
Local  applications  will  restore  the  skin  to  its  normal  state  in  nearly  all  cases,  while  in  many 
it  is  extremely  difficult  to  prevent  relapses,  even  with  internal  treatment.  Most  cases  of  psoria- 
sis demand  a  combination  of  internal  and  external  treatment,  but  where  the  general  health  is 
good,  local  treatment  is  of  chief  importance.  In  estimating  the  value  of  any  local  applica- 
tion or  plan  of  treatment  it  must  always  be  borne  in  mind  that  psoriasis  is  rarely  stationary, 
but  tends  to  improve  or  to  completely  disappear  at  certain  seasons  of  the  year.  The  value 
of  a  remedy  can  only  be  determined,  therefore,  by  observation  of  its  effect  in  a  number  of  cases.

PSORIASIS     DIFFUSA 


Tft,  i.  BltRSTAOr 


PSORIASIS. 

In  the  local  treatment  of  psoriasis,  our  aim  should  be  three-fold,  viz.,  to  soothe  the  bk;;i. 
to  soften  and  remove  the  scales,  and  to  promote  absorption  of  the  infiltrated  patches.  In  no 
disease  of  the  skin  is  bathing  of  more  importance  than  in  psoriasis.  The  Turkish  bath  ful- 
fils each  of  the  three  indications  above  mentioned,  and  often  does  more  to  improve  the  general 
health  of  the  patient  than  the  administration  of  drugs.  When  the  psoriatic  patches  are  red 
itchy  and  irritable,  as  they  frequently  are,  the  mistake  is  too  often  made  of  giving  arsenic  in 
ternally,  and  applying  stimulating  applications  to  the  diseased  skin.  It  is  far  better,  in  such 
cases,  to  prescribe  a  daily  bath  with  inunction  of  cosmoline,  or  vaseline,  until  the  acute 
inflammatory  symptoms  have  subsided.  Intense  itching  may  be  allayed  by  means  of  a  lotion 
of  carbolic  acid  (10-15  per  cent.)  in  glycerine.  The  irritability  of  the  patches  being  subdued 
soap  frictions  may  be  added  to  the  bath  to  remove  the  accumulated  epidermis,  although,  when 
the  scales  are  but  moderately  thick,  they  are  quickly  softened  and  removed  by  the  stimula- 
ting application  employed  to  lessen  the  infiltration  of  the  skin.  When  in  inveterate  cases 
the  scales  ai-e  like  plates  of  horny  armor,  they  need  to  be  softened  by  painting  them  with 
acetic  acid  and  scraping  them  off  with  a  curette,  or  by  enveloping  the  limb,  or  even  the  body, 
in  a  close-fitting  garment  of  vulcanized  rubber  cloth,  worn  with  the  smooth  side  next  to  the 
skin.  To  the  red  and  thickened  patches  now  exposed  may  be  applied  one  of  numerous 
stimulating  remedies  of  variable  strength.  Tar  has  been  most  extensively  employed,  and  its 
most  convenient  form,  the  oil  of  cade,  is  a  serviceable  application. 

But  the  use  of  tar  in  psoriasis  has  been  completely  superseded  within  the  past  ten  years 
by  the  introduction  of  chrysarobin.  This  remedy  has  grown  steadily  in  favor  with  the  pro- 
fession until  it  has  attained  a  recognition  as  one  of  the  foremost  agents  in  the  local  treatment 
of  various  chronic  diseases  of  the  skin. 

For  several  years  after  the  introduction  of  this  drug  (under  the  name  of  chrysophanic 
acid)  it  was  used  in  the  form  of  an  ointment  of  varying  strength,  and  scarcely  any  one  who 
tested  its  value  failed  to  be  struck  by  its  peculiar  effect  upon  the  sound  skin,  and  surprised 
at  its  beneficial  action  upon  diseased  patches.  But  there  were  objectionable  features  con- 
nected with  its  use  in  the  form  of  an  ointment,  which  could  not  be  overlooked,  and  these  were 
often  so  marked  that  they  served  in  many  instances  to  counterbalance  the  value  of  the  reme- 
dy. In  all  cases  the  healthy  skin  became  temporarily  discolored,  which  was  not  a  very 
serious  matter,  but  at  the  same  time  the  underclothing  of  the  patient  became  permanently 
stained  and  usually  ruined  by  a  single  application  of  the  ointment.  Furthermore,  the  effect 
of  the  remedy  was  found  to  be  somewhat  different  in  degree  upon  different  skins,  and  in 
some  cases  a  violent  dermatitis  was  occasioned  even  by  the  use  of  mild  ointment,  and  this 
often  proved  to  be  worse  than  the  disease  for  which  it  was  applied.  Under  these  circum. 
stances  many  were  led  to  give  up  the  use  of  the  remedy,  while  a  few  were  prompted  to  seek 
a  means  which  would  obviate  its  objectionable  qualities  without  impairing  its  efficacy  in  any 
marked  degree.  The  efforts  of  the  latter  have  been  finally  cro\vned  with  success,  and  it  may 
be  now  asserted  that  the  local  effect  of  chrysarobin  can  be  obtained  without  danger  of  its  ex 
citing  a  dermatitis  of  the  healthy  skin  or  causing  a  discoloration  of  the  patient's  clothing. 

(81) 


DISEASES  OF  TEE  SKIN.— INFLAMMATORY. 

Various  experimenters,  both  here  and  in  Europe,  have  adopted  different  means  to  obtain  thia 
result,  untU  all  have  arrived  at  the  conclusion  that  the  chrysarobin  must  be  incorporated  in 
some  elastic  and  adhesive  varnish. 

My  first  attempts  to  solve  the  question  led  me  to  the  employment  of  a  paste  made  by 
mixing  the  chysarobin  powder  with  a  quantity  of  water.  This  was  applied  to  the  affected 
Bkin  and  covered  with  flexible  collodion,  or  a  little  absorbent  cotton  moistened  with  the  white 
of  an  egg,  or  a  piece  of  gutta  percha  tissue,  the  edges  of  which  were  glued  to  the  skin  by 
means  of  chloroform.  This  plan  was  effective  but  troublesome.  I  also  tried  chrysarobin 
sprinkled  on  plaster,  and  other  devices  which  I  need  not  mention.  Finally  I  resorted  to  a 
mixture  of  chrysarobin  and  collodion,  which  made  a  neater  application,  though  it  lessened 
somewhat  the  activity  of  the  remedy.  About  a  year  or  more  ago,  having  observed  the  pe- 
culiar effect  of  salicylic  acid  in  softening  corns  and  epidermic  tissue  in  the  form  of  scales,  it 
occurred  to  me  to  combine  this  remedy  with  the  chrysarobin  in  coUodion,  and  my  subsequent 
use  of  this  pigment  or  varnish  in  both  private  and  hospital  practice  has  convinced  me  that 
this  combination  greatly  enhances  the  value  of  the  simple  chrysarobin  in  collodion.  It  ap- 
parently causes  it  to  adhere  more  firmly  to  the  skin,  and  to  produce  a  more  marked  effect 
upon  the  diseased  patches.  The  formula  which  I  have  employed  with  the  greatest  satisfac- 
tion, and  which  at  the  New  York  Skin  and  Cancer  Hospital  is  known  as  the  "  Pigmentum 
Chrysarobini  Compositum,"  is  the  following : 

9-    Chrysarobin, 10  parts. 

Salicylic  Acid, 10     " 

Ether, 15      " 

Flexible  CoUodion,  to  -  -  -  100  " 
M. 
In  Europe  the  mixture  of  chrysarobin  and  coUodion  has  been  recommended  by  Sese- 
mann,  whUe  gelatine  has  been  employed  as  a  vehicle  for  the  chrysarobin  by  Unna  and  Pick. 
Recently  Auspitz  has  recommended  the  use  of  chrysarobin  in  a  solution  of  gutta-percha.  I 
have  used  this  application  in  the  treatment  of  a  number  of  cases  of  psoriasis  and  it  is  certainly 
an  elegant  and  efiicacious  one.  The  chloroform  has  the  advantage  over  ether  in  dissolving  a 
trifle  more  of  the  chrysarobia,  but  the  efficacy  of  the  application  would  be  increased,  in  my 
opinion,  by  the  addition  of  ten  per  cent,  of  the  salicylic  acid,  for  the  reasons  which  I  have 
already  stated.  The  use  of  the  liquor  gutta-perchse,  U.  S.  P.,  as  a  vehicle  for  the  chrysaro- 
bin and  saUcyUc  acid  is  weU  adapted  to  use  in  private  practice,  but  the  use  of  coUodion  as  in 
the  formula  given  above  is  more  desirable  in  hospital  and  dispensary  practice,  as  the  cost  of 
the  latter  pigment  is  one-half  that  of  the  former.  Of  course,  it  must  be  carefuUy  kept  in  a 
well-corked  and  preferably  in  a  wide-mouthed  bottle.  It  can  be  applied  to  the  diseased  skin 
by  means  of  a  smaU  stiff  paint  brush,  and  should  the  pigment  become  slightly  thick  at  any 
time,  it  can  be  made  as  thin  as  desirable  by  the  addition  of  a  small  quantity  of  ether.  In 
some  cases  it  is  advisable  to  apply  the  remedy  in  the  form  of  a  thick  varnish,  whUe  in  other 
cases,  where  only  a  sUght  effect  is  required,  it  is  better  to  apply  only  a  thin  coating.     For 

(82)

this  purpose  a  larger  quantity  of  ether  should  be  used  in  the  formula  given  above.  Occa- 
sionally the  pigment  produces  temporarily  a  stinging  sensation,  but  this  is  scarcely  worthy 
of  mention  when  we  consider  the  perfect  relief  from  itching  which  frequently  ensues.  The 
yellow  coating  upon  the  skin  dries  very  quickly,  and  if  not  disturbed  by  unusual  friction  or 
bathing,  it  remains  upon  the  skin  without  incommoding  the  patient  in  the  slightest  degree 
for  sevei-al  days.  It  then  begins  to  fall  off,  and  usually  requires  a  renewal.  When  severe 
pruritus  has  been  present  and  is  relieved,  as  is  commonly  the  case  upon  application  of  the 
pigment,  a  second  application  should  be  made  as  soon  as  the  coating  begins  to  crack  or  peel, 
as  at  this  stage  the  prm-itus  is  very  apt  to  return. 

In  the  local  treatment  of  psoriasis  chrysarobin  is  without  doubt  a  truly  great  remedy. 
No  one  can  fail  to  appreciate  and  be  thankful  for  the  progress  of  medical  science  who  con 
siders  how,  less  than  ten  years  ago,  psoriatic  jjatients  were  persistently  smeared  ^vith  tar,  and 
often  smeared  in  vain,  and  appreciates  the  fact  that  now  it  is  a  comparatively  simple  matter 
to  cause  a  speedy  disappearance  of  the  scaly  patches  in  nearly  every  case.  And  it  is  another 
step  in  advance  which  has  superseded  the  ointment  of  chrysarobin  by  applications  of  the 
remedy  which  do  not  ruin  the  clothing  and  inflame  the  healthy  skin.  In  the  treatment  of 
psoriasis  the  compound  chrysarobin  pigment  is,  in  my  opinion,  the  best  application  which  can 
be  employed  in  at  least  ninety  per  cent,  of  cases,  and  may  be  applied  to  all  parts  of  the  body 
with  the  exception  of  the  scalp  and  face.  Here,  the  use  of  ammoniated  mercury  oiatment, 
which  is  of  little  value  when  applied  to  the  trunk  and  extremities,  will  generally  suffice  to 
remove  the  eruption  in  a  very  short  time. 

Of  the  internal  treatment  of  psoriasis  but  little  need  be  said.  While  in  no  other  affec- 
tion of  the  skin  has  such  a  wonderful  improvement  in  the  method  of  local  treatment  taken 
place  of  late,  our  knowledge  of  the  nature  and  internal  treatment  of  psoriasis  has  not  ma- 
terially advanced.  I  have  tried  antimony,  carbonate  of  ammonia,  chrysarobin,  and  a  few 
other  drugs  recommended  for  internal  use  in  this  disease,  but  without  observing  any  marked 
benefit. 

Psoriatic  patients  are  not  usually  in  need  of  tonics.  Some  errors  in  digestion  may  be 
discovered  and  require  to  be  corrected.  An  alkaline  plan  of  treatment  may  be  called  for  by 
the  association  of  the  disease  with  a  rheumatic  or  gouty  habit,  and  should  be  our  chief  reli- 
ance whenever  the  patches  are  hypersemic  and  irritable.  The  acetate  or  citrate  of  potassium 
may  be  given  in  from  one  to  two  gram  doses  (fifteen  to  thirty  grains),  in  a  half  glass  of  water, 
a  short  time  before  meals.  In  chronic  cases  arsenic  is  an  old,  a  well-tested  and  an  efficient 
remedy.  It  may  be  given  in  the  form  of  the  liq.  potassii  arsenitis,  the  liq.  arsenici  chloridi, 
or  the  so-called  Asiatic  pills  converted  into  a  powder  (Piffard).

the  food  in  the  place  of  salt,  if  agreeable  to  the  patient.  Before  the  effect  of  the  arsenic 
upon  the  eruption  in  any  given  case  can  be  observed,  the  patches  can  be  usually  removed  by 
a  resort  to  the  local  treatment  already  described,  but  the  drug  will  often  prove  useful  in  pre- 
venting a  relapse. 

MILIARIA. 

Synonyms — Lichen  Tropicus — Lichen  jSstivtis — Prickly  Heat. 

Miliaria  is  a  fine  papular  or  papulo-vesicular  eruption,  which  is  very  common,  not  only 
in  the  tropics  but  in  temperate  climates,  especially  during  the  excessive  heat  of  midsummer. 
The  lesions  consist  of  minute  conical  elevations  of  the  skin,  closely  aggregated,  and  of  a 
bright  red  hue.  When  fully  developed,  the  summit  of  each  lesion  presents  a  whitish  appear- 
ance from  the  effusion  of  the  minutest  drop  of  serum.  The  eruption  is  generally  limited  to 
a  portion  of  the  trunk,  but  may  appear  upon  the  face,  neck  and  extremities.  Only  in  excep- 
tional instances  is  the  eruption  general.  The  skin  is  usually  bathed  in  perspiration,  and 
there  is  always  present  a  peculiarly  annoying  sensation  which  has  given  to  the  affection  its 
common  name  of  "prickly  heat."  The  adjectives  alba  and  rubra  are  sometimes  employed 
in  connection  with  the  term  Miliaria,  to  indicate  the  degree  of  congestion  of  the  skin  and 
resulting  color  of  the  eruption. 

The  cause  of  Miliaria  is  to  be  found  in  a  combination  of  agencies,  which  conspire  to  pro- 
duce an  undue  congestion  of  the  skin.  Hot  weathei',  excess  of  clothing,  and  vigorous  exer- 
cise commonly  evoke  the  eruption.  It  is  most  common  among  children,  especially  such  as 
are  debilitated  and  poorly  cared  for.  Among  adults  it  is  not  infrequent,  and  is  most  apt  to 
affect  those  whose  vitality  is  lowered  by  dissipation  of  various  kinds.  The  free  use  of  alco- 
holic stimulants  in  hot  weather  often  induces  the  eruption,  and  aggravates  it  when  resulting 
from  other  causes.  Miliaria  is  especially  common  among  those  who  have  a  fair  complexion 
and  thin  delicate  skin. 

Diagnosis.  The  eruption  is  generally  recognized  without  difficulty  when  existing  alone, 
but  as  not  infrequently  occurs  in  connection  with  a  papular  eczema,  a  mistake  in  diagnosis 
may  now  and  then  occur.  The  larger  size  of  the  papules  in  eczema,  their  more  scattered 
distribution,  and  the  itching  which  attends  them  and  results  in  the  excoriation  of  their  sum- 
mits, will  serve  as  a  distinctive  feature.  Chicken  pox  and  German  measles,  occurring  in  hot 
weather,  have  been  mistaken  for  prickly  heat,  but  no  careful  physician  ought  to  be  led  into 
such  an  error. 

Treatment.  The  chief  aim  in  the  treatment  of  Miliaria  is  to  keep  the  skin  as  cool  as 
possible.  To  accomplish  this  end,  the  exciting  causes  already  mentioned  must  be  avoided. 
Work  and  worry  should  be  reduced  to  a  minimum,  and  one  or  more  cool  baths  taken  daily. 
Rest,  light  clothing,  and  frequent  draughts  of  lemonade,  or  some  other  cooling  beverage^ 
will  speedily  check  the  eruption  in  the  case  of  adults.  In  children  the  affection  is  apt  to  be 
more  troublesome,  and  sometimes  persists  for  weeks  in  a  more  or  less  aggravated  form.     The

remedies  which  I  have  generally  advised,  and  found  nsefnl,  are  two  which  are  commonly 
found  in  every  household,  viz  :  cream  of  tartar  internally,  and  starch  powder  locally.  A 
teaspoonful  of  the  cream  of  tartar  may  be  stirred  up  in  a  glass  of  water,  and  a  few  swallows 
taken  every  half  hour.  Locally,  an  absorbent  powder  will  prove  far  more  agreeable  than  an 
ointment. 


LICHEN  PLANUS. 

Synonym — Lichen  Ruber  Planus. 

Lichen  is  a  name  which  was  applied  by  the  older  dermatologists  to  all  diseases  of  the 
skin,  the  lesions  of  which  consist  of  persistent  papules.  Several  varieties  of  lichen  are 
described,  but  as  a  more  careful  study  of  the  natural  history  of  skin  diseases  has  shown  that 
these  are  not  varieties  of  one  disease,  but  papular  stages  or  forms  of  widely  different  dis- 
eases, most  of  them  have  become  obsolete  as  forms  of  lichen,  being  known  at  present  under 
different  and  more  appropriate  names.  Lichen  simplex,  according  to  many  writers,  is  noth- 
ing more  nor  less  than  a  papular  form  of  eczema  (See  plate  of  E.  papulosum).  Lichen  lividus 
is  Purpura  papulosa ;  Lichen  urticatus  is  Urticaria  papulosa ;  while  Lichen  syphiliticus  is 
Syphiloderma  papulosum,  a  name  expressing  the  nature  of  the  disease,  which  is,  of  course, 
of  vastly  more  importance  than  the  form  and  appearance  of  cutaneous  lesion.  There  still 
occur,  however,  papular  eruptions  which  cannot  be  considered  as  mere  papular  foi-ms  of  any 
disease  otherwise  named,  and  to  such  the  term  "Lichen  "  is  justly  applied. 

Lichen  planus  consists  in  an  eruption  of  peculiar  papules,  which  may  be  disseminated 
or  aggregated,  and  either  occupy  a  limited  region,  or  extend  over  a  large  extent  of  the  general 
surface  of  the  skin.  The  chief  peculiarity  of  the  papules,  and  one  which  gives  rise  to  the 
name,  is  their  flattened  summit.  They  are  but  slightly  elevated,  and  though  rising  abruptly 
from  the  healthy  skin,  they  do  not  possess  the  conical  or  rounded  summit  of  ordinary  pap- 
ules, but  appear  as  though  they  had  been  shaved  off  or  pressed  dowTi.  The  summit  is  smooth 
and  horny,  and  sometimes  presents  a  glistening  appearance.  Usually  a  punctate  depression, 
or  umbilication,  is  seen  in  the  centre  of  this  flattened  surface.  The  base  of  the  papule  is 
often  angular  in  its  outline.  Li  size,  the  papules  vary  greatly  in  different  cases,  and  slightly 
upon  different  portions  of  the  body.  They  are  usually  of  the  size  of  a  pin's  head,  biit  may 
be  considerably  larger.  As  in  the  case  of  the  papular  syphilide,  both  a  miliary  and  a  lentic- 
ular form  of  Lichen  planus  may  occur.  The  color  is  a  pale  yellowish  red  when  the  papules 
are  small,  and  ' '  dull  crimson,"  or  violaceous,  when  they  are  larger,  the  centre  being  somewhat 
lighter  than  the  rim  of  the  papule.  The  papules  may  be  regularly  disseminated  over  a  given 
surface,  or  strewn  in  groups,  even  when  not  coalescing.  The  papules,  when  once  developed, 
persist  as  such,  never  evincing  the  slightest  tendency  to  vesiculation  or  pustulation.  They 
do  not  increase  in  size,  and  patches  are  formed  by  the  springing  up  of  new  papules  amonir 
the  older  ones.  The  isolated  papules  are  not  scaly  ;  but  when  they  become  aggregated,  the}" 
lose  their  peculiarities  of  form  and  appearance,  and  irregular  patches  of  thickened  skin  result,

DISEASES  OF  TEE  SKIN.— INFLAMMATORY. 

with  a  dry,  haxsh,  homy  surface,  which  to  the  touch  feels  like  a  file,  or  even  a  nutmeg 
grater.  At  the  border  of  such  a  patch  the  typical  papules  may  sometimes  be  observed.  The 
disease  is  attended  with  a  certain  amount  of  itching  in  every  case,  and  the  utmost  distress  is 
sometimes  occasioned  by  this  symptom.  It  develops  with  variable  rapidity,  requiring  but  a 
few  weeks,  in  some  cases,  to  produce  an  extensive  eruption.  Limited  patches,  on  the  other 
hand,  often  remain  for  months  without  change.  The  disease  is  chronic  in  most  cases,  and 
shows  little  disposition  to  yield  readily  to  treatment.  The  anterior  surface  of  the  fore-arm 
and  wrist  is  the  most  favorite  locality. 

The  cause  of  the  affection  is  obscure.  It  is  certain,  however,  that  those  affected  by  i1 
are  far  from  being  in  perfect  health.  The  debilitated  condition  of  the  system  in  this  disease 
is  more  noticeable  than  in  eczema,  and  far  more  so  than  in  psoriasis.  The  eruption  may 
occur  in  either  sex,  in  the  young  as  well  as  the  old,  and  upon  almost  any  portion  of  the 
body.  It  occurs  far  more  frequently  in  females,  according  to  my  experience,  and  usually 
in  middle  life. 

Diagnosis.  The  diagnosis  of  Lichen  planus  is  not  generally  difficult  for  one  who  has 
had  the  opportunity  of  seeing  a  well-marked  case  of  the  affection.  But,  as  the  disease  is  com- 
paratively rare,  the  reader  may  be  caUed  upon  to  diagnose  and  treat  a  case  without  this  ad- 
vantage. If  the  case  is  typical  it  will  correspond  with  the  description  given,  and  with  that 
of  no  other  disease.  The  papular  syphilide  ought  not  to  be  mistaken  for  it,  owing  to  the 
regular  distribution  of  papules  over  the  body,  and  the  absence  of  itching  in  the  former  affec- 
tion. The  papules  of  eczema  are  itchy,  often  affect  a  limited  region,  may  be  both  disseminate 
and  grouped,  and  resemble  Lichen  planus  at  first  glance.  They  are  brighter  in  color,  how- 
ever, conical  in  form,  and  never  present  the  angular  base,  flattened  summit,  and  central  de- 
pression, which  characterize  the  papules  of  the  latter  affection. 

Treatment.  The  general  health  in  many  cases  being  impaired  in  a  greater  or  less  degree, 
the  strictest  attention  should  be  paid  to  dietary  or  hygienic  measures.  The  digestive  organs 
must  be  kept  in  as  normal  a  condition  as  possible,  and  the  most  nourishing  and  easily  digested 
food  prescribed.  Of  internal  remedies,  the  alkaline  diuretics  seem  to  be  productive  of  the 
best  results  by  reetiving  the  cutaneous  congestion.  In  many  cases  of  this  disease,  and  indeed 
in  any  case  of  chronic  skin  disease  where  an  imperfect  oxygenation  of  the  blood  exists,  it  is 
advisable  to  administer  a  gram  (fifteen  grains)  or  more  of  chlorate  of  potassium,  fifteen  min- 
utes after  each  meal,  and  twenty  drops  of  dilute  nitric  acid  in  water,  fifteen  minutes  later. 
Wilson  recommends  quinine,  nitro-muriatic  acid  and  chalybeates.

LICHEN  RUBER. 

Tlie  best  local  treatment  wliicli  I  have  used  is  tlie  application  of  carbolic  acid  in  full 
strengtli  to  the  patches  and  to  the  scattered  lesions.  This  lessens  the  hypersemia  and  promi- 
nence of  the  papules,  and  soon  converts  them  into  dull,  red  upots,  which  slowly  disappear. 

LICHEN   RUBER. 

Lichen  ruber  was  first  recognized  as  a  distinct  affection  of  the  skin  by  Hebra,  who  selected 
the  name  on  account  of  the  development  of  papules,  and  the  duU  red  hue  which  they  present 
when  not  whitened  by  a  slight  desquamation  of  the  epidermis.  The  disease,  as  described  by 
Hebra,  is  one  of  the  rarest  of  cutaneous  affections. 

A  case  reported  by  Dr.  White,  of  Boston,  a  case  of  Dr.  SherweU,  of  Brooklyn,  illus- 
trated in  the  first  edition  of  this  work,  a  case  under  the  care  of  Dr.  McMaster,  of  New  York, 
and  the  subject  of  the  accompanying  plate,  are  among  the  few  cases  of  true  lichen  ruber 
which  have  been  recognized  in  this  country.  A  number  of  cases  of  extensive  lichen  planus, 
involving  both  trunk  and  extremities  I  have  seen,  but  these  seein  to  me  to  differ  in  their  na- 
ture from  the  lichen  ruber  of  the  Germans  ;  and  from  my  clinical  study  of  cases  at  home  and 
abroad,  I  am  disposed  to  differ  with  the  majority  of  dermatologists  who  associate  lichen 
planus  described  first  by  Wilson,  and  later  by  other  English  dermatologists,  with  the  lichen 
ruber  of  Hebra  and  other  German  writers. 

Piffard  is  inclined  to  believe  that  the  affections  are  distinct,  and  writes  as  foUows :  "  This 
view,  that  L.  planus  and  ruher  are  identical,  supported  by  such  eminent  authority,  is  very 
plausible,  and  might  be  accepted  as  definite,  were  it  not  for  certain  prominent  facts  which  its 
advocates  fail  to  satisfactorily  explain.  In  the  first  place,  Wilson  observed  fifty  cases  of  L. 
planus  characterized  by  umbilicated  papules  and  pigment  stains,  most  of  which  pursued  a  be- 
nign course.  Hebra  observed  fourteen  cases  without  umbilicated  papules  or  stains,  most  of 
which  terminated  fatally.  It  is  hardly  supposable  that  a  careful  observer  like  Hebra  would  have 
overlooked  the  umbUications,  if  present,  or  that  Wilson  should  have  met  with  mild  cases 
only,  and  Hebra  with  severe  ones.  Now,  subsequent  to  Wilson's  publication,  Hebra  and 
Kaposi  have  observed  a  number  of  examples  of  a  benign,  umbilicated,  papular  eruption, 
which  they  have  included  under  their  old  name  of  '■ruber.''  It  does  not  follow,  however, 
that  because  they  have  done  this,  that  the  two  are  the  same  disease.  Neumann,  in  1868, 
described  the  microscopical  appearance  of  the  original  L.  ruber ^  and  Biesiadecki,  in  1872, 
those  of  the  umbilicated  eruption.  As  will  be  seen  later,  these  differ  widely.  Lastly,  no 
one,  so  far  as  I  am  aware,  has  seen  the  transition  of  a  typical  L.  planus  into  L.  ruber. ^'  The 
latest  microscopical  investigations  into  the  natiu'e  of  the  affections  by  A.  R.  Robinson  tend 
to  show  this  non-identity.  After  a  careful  comparison  of  the  symptoms,  histology,  prognosis 
and  treatment  of  the  two  forms  of  eruption,  this  writer  concludes  that  lichen  ruber  and 
lichen  planus  are  two  entirely  distinct  diseases  of  the  skin,  and  that  the  grounds  for  regard- 
ing them  as  but  two  forms  of  the  same  disease  are  altogether  untenable. 

In  many  respects  lichen  ruber  resembles  lichen  planus,  and  it  is  only  necessary  to  refer 

(87) 


DISEASES  OF  THE  SKIN— INFLAMMATORY. 

briefly  to  certain  points  of  difference,  without  discussing  the  question  as  to  whether  the  two 
are  distinct  affections  or  forms  of  the  same  disease.  The  papules  at  the  outset  are  of  a 
brighter  red  color,  conical  in  shape,  and  surmounted  by  a  thin,  adherent  scale.  ^Vhen  aggre- 
gated, as  is  usually  the  case,  the  same  roughened  surface  is  produced  as  in  lichen  planus. 

The  eruption  affects  no  particular  locality,  but  tends  to  become  general.  The  naUs  suffer 
In  a  characteristic  manner,  becoming  thickened,  with  an  uneven  surface  and  a  broken  ex- 
tremity. This  condition,  together  with  the  infiltration  of  the  skin,  interferes  considerably 
with  the  free  use  of  the  hands  and  feet.  When  the  disease  has  existed  for  some  time,  the 
patient  tends  to  become  emaciated,  and  in  time  the  strength  fails,  and  death  ensues.  The  differ- 
ent prognosis  given  by  different  writers  results  evidently  from  the  fact  that  some  confound 
the  general  eruption  of  lichen  planus  Avith  the  true  lichen  ruber.  Whereas,  a  cure  may 
confidently  be  expected  in  the  one  case,  it  can  only  be  hoped  for  in  tLe  other. 

As  to  the  pathological  nature  of  lichen  ruber,  Auspitz  denies  that  it  is  an  inflammatory 
affection,  and  claims  that  the  lesions  result  from  a  hypertrophic  gro^^'th  of  the  corneous 
layer.  In  this  view  he  is  supported  by  Eobinson,  who  states  that  the  primary  and  principal 
changes  in  lichen  ruber  occur  in  the  corneous  layer  and  are  never  the  result  of  an  inflamma- 
tion. He  says:  "From  a  clinical  study  of  the  papule  there  is  also  nothing  in  its  mode  of 
origin  or  appearance  which  makes  it  probable  that  the  disease  is  an  inflammatory  one.  The 
redness  present  is  principally  a  hypersemic  redness,  as  shown  by  the  absence  of  an  inflamma- 
tory areola,  there  is  no  pus-formation,  no  abscess,  no  vesicles,  no  erosion,  no  exudation  upon 
the  free  surface,  no  inflammatory  infiltration  into  the  cutis,  no  pain  ;  no  increase  of  temjpera- 
ture,  judging  by  the  feel — in  other  words,  the  essential  clinical  characters  of  an  inflamma- 
tion are  absent." 

Treatment.  In  lichen  ruber,  a  long  continued  course  of  arsenic  is  advised  by  Hebra, 
whUe  the  effect  of  the  linseed  oil  treatment  of  Dr.  SherweU,  in  the  case  illustrated  in  the  first 
edition  of  this  work,  would  suggest  its  trial  in  other  cases.  Locally,  baths  and  other  sooth- 
ing measures  are  called  for  when  the  amount  of  congestion  is  extreme. 

LICHEN  SCROFULOSUS- 

This  is  an  affection  which  is  rarely  met  with  in  this  country.  The  eruption  is  a  chronic 
one,  and  is  characterized  by  groups  of  smaU,  pale  red  and  scaly  papules,  which  usually  are 
located  upon  the  trunk  and  are  not  itchy.  The  affection  is  most  frequently  observed  in  boys, 
and  as  the  name  implies,  is  commonly  associated  with  marked  evidences  of  a  scrofulous  dia- 
thesis. Hebra,  who  first  described  the  disease,  treated  all  of  the  cases  successfully  by  cod 
liver  oU,  internally  and  externally. 

PRURIGO. 

This  is  another  affection  which  is  rare  in  this  country,  though  comparatively  common  in 
certain  parts  of  Europe.    The  name  Prurigo  is  often  applied  to  certain  itchy  affections  which 

(88) 


HERPES    FAC 


PRTJRIOO. 

were  classed  under  tMs  head  by  Willan  and  later  Englisli  dermatologists,  but  it  should  be 
restricted  to  a  peculiar  and  extremely  chronic  eruption  which  affects  chiefly  the  extensor 
surfaces  of  the  extremities,  and  is  accompanied  by  the  most  intense  pruritus. 

The  affection  is  never  hereditary  nor  contagious.  It  is  most  likely  to  affect  weakly  or 
poorly  nourished  children,  and  especially  those  whose  parents  have  sho\vn  evidences  of 
tuberculosis.     It  is  rare  to  find  more  than  one  child  in  a  family  suffering  from  this  disease. 

Diagnosis.  Prurigo  is  so  rare  in  this  country  that  only  a  few  undoubted  cases  have 
been  reported.  In  my  own  experience  I  have  never  met  with  a  typical  case,  such  as  may  be 
seen  daUy  in  the  Vienna  clinics,  but  have  treated  several  which  were  of  a  mild  type  of  the 
affection.  Many  experienced  dermatologists  in  this  country  are  disposed  to  dispute  the  cor- 
rectness of  the  diagnosis  of  prurigo,  if  the  well-marked  symptoms  of  the  disease,  as  they 
have  studied  it  abroad,  are  not  present.  But  it  must  be  borne  in  mind  that  only  the  most  strik- 
ing cases  of  prui'igo  agria  are  exhibited  in  the  Vienna  clinics,  and  that  the  mild  form  of  the 
disease  does  not  present  the  well-marked  thickening  and  pigmentation  of  skin,  with  the  ac- 
companying buboes,  which  are  characteristic  of  the  severer  form  of  the  disease.  It  appears 
to  me  quite  probable,  therefore,  that  many  mild  cases  of  prurigo  are  overlooked  in  this 
country,  cases  which  could  pass  readily  as  prurigo  mitis  in  Germany.  In  its  incipient  stage 
the  affection  might  easily  be  mistaken  for  an  urticaria  of  the  extremities,  as  wheals  and 
excoriations  are  the  only  lesions.  But  the  persistence  of  the  disease  for  months  and  years 
in  spite  of  ordinary  treatment  and  their  characteristic  localization,  ought  in  time  to  reveal 
the  true  nature  of  the  disease.  The  artificial  eczema,  so  commonly  jDresent  in  severe  prurigo, 
tends  usually  to  obscure  the  diagnosis,  but  here  again  the  seat  and  persistence  of  the  erup- 
tion is  a  guide.  While  eczema  is  especially  apt  to  occur  upon  the  flexor  aspect  of  the  joints, 
where  the  skin  is  thin  and  delicate,  prurigo,  of  however  intense  a  grade,  invariably  leaves 
these  parts  unaffected.  The  eruption  of  scabies  often  bears  a  strong  resemblance  to  mild 
prurigo  upon  the  extremities ;  but  whUe  the  former  affection  is  most  noticeable  as  a  rule  upon 
the  hands  and  certain  portions  of  the  trunk,  the  latter  affection  is  most  marked  upon  the 
extremities. 

Treatment.  There  are  few  affections  of  the  skin  and  none  of  the  inflammatory  group 
which  are  more  intractable  than  prurigo.  Taken  at  the  outset,  a  favorable  progress  may  be 
made,  but  when  the  disease  has  existed  for  a  long  time  its  cure  is  by  no  means  an  easy  mat- 
ter, and  under  the  most  favorable  circumstances  the  treatment  must  be  continued  for  a  year 
or  more.  In  some  cases  relapses  are  inevitable  after  an  apparent  cure,  while  in  others  the 
most  that  can  be  hoped  for  is  an  alleviation  of  the  patient's  misery.  Often  the  disease  per- 
sists throughout  the  patient's  life,  which  is  very  apt  to  be  shortened  by  the  suffering  which 
it  entails. 

The  first  aim  in  treatment  will  usually  be  the  cure  of  the  artificial  eczema  which  is  so 
often  present,  and  to  effect  this  the  applications  already  recommended  in  connection  with 
eczema  may  be  employed.  The  next  aim  mil  be  to  lessen  the  infiltration  of  the  skin,  and 
thereby  relieve  the  pruritus  which  is  so  harassing  to  the  patient.     The  use  of  tar  is  advisable 


DISEASES  OF  TEE  SKIN— INFLAMMATORY. 

to  effect  this  end,  or  if  the  eczema  has  been  completely  subdued,  Vleminckx  solution,  as 
recommended  by  Hebra,  may  be  rubbed  over  the  thickened  skin  and  the  patient  placed  for 
an  hour  in  a  warm  bath.  This  may  be  repeated  daily  for  several  weeks,  and  then  continued 
at  intervals.  After  the  bath  the  body  should  be  anointed  with  lard  or  petroleum  to  coun- 
teract the  caustic  effect  of  the  lime  in  the  solution  mentioned,  which  is  prepared  according  to 
the  following  formula.

The  general  health  of  the  patient  must  be  improved  in  every  possible  way. 

HERPES. 

Herpes,  a  term  old  enough  to  have  been  used  by  Hippocrates,  has  been  applied,  by  wri- 
ters in  times  past,  to  numerous  and  varied  affections.  Even  at  the  present  time  there  are 
some  who  apply  it,  with  varying  adjectives,  to  both  vesicular  and  bullous,  as  weU  as  to  para- 
sitic, affections.  The  tendency  of  modern  dermatology  has  been  toward  a  limited  applica- 
tion of  the  term  to  acute  affections,  characterized  by  the  development  of  vesicles  in  groups. 
From  a  clinical  point  of  view,  I  deem  it  advisable  to  regard  zoster  and  erythema  buUosum 
(hydroa),  two  vesicular  or  vesiculo-bullous  affections,  as  distinct  from  the  ordinary  herpes, 
60  frequently  met  with  upon  the  lips  and  prepuce. 

Herpes  may  be  defined  as  an  acute  inllamatory  affection,  consisting  of  one  or  more  groups 
of  vesicles,  occurring  on  the  face  or  external  genitals,  and  in  the  foi-mer  location  accom- 
panied frequently  by  fever.  This  definition  limits  the  application  of  the  term  to  two  com- 
paratively insignificant  forms  of  vesicular  eruption,  called  in  accordance  with  the  regions 
affected,  H.  facialis  and  H.  progenitalis. 

Herpes /aciaZi^,  in  its  most  frequent  form,  is  met  with  upon  the  margin  of  the  lips,  consti- 
tuting what  is  commonly  termed  a  cold  sore  (H.  Idbialis).  The  vesicles,  in  such  a  case,  are  not 
usually  distinct,  and  the  person  affected  may  note  but  one  or  more  slight  swellings  of  the 
lip,  attended  by  an  unpleasant  burning  sensation,  and  the  rapid  development  of  a  thin  crust 
or  scab.  The  affection  may  result  from  no  apparent  cause,  but  the  patient  is  frequently  con- 
scious of  having  "  caught  a  cold."  The  eruption  often  extends  from  the  vermilion  border  of 
the  lip  upon  the  cutaneous  surface,  and  groups  of  vesicles  are  seen  upon  the  side  of  the  nose  and 
cheeks.  When  developed  to  this  extent,  the  eruption,  particularly  in  children,  is  apt  to  be 
associated  \vith  more  or  less  fever.  In  rare  instances,  the  forehead,  eyelids,  ears,  as  well  as  the 
mucous  surface  of  the  tongue  and  buccal  cavity  become  the  seat  of  the  eruption.  However  nu- 
merous may  be  the  group  of  vesicles,  they  are  usually  developed  simultaneously,  the  affection 
differing  in  this  respect  from  zoster  and  hydroa.     The  vesicles  develop  upon  an  erythematous

base,  are  rouuded  and  tense,  and  though  larger  than  the  vesicles  of  eczema,  are  not  equal  in  size 
to  those  seen  in  cases  of  erythema  buUosum.  An  uncomfortable,  burning  sensation  accom- 
panies their  outbreak,  but  subsides  as  soon  as  the  eruption  has  attained  its  maximum  devel- 
opment. There  is  never  any  of  the  neuralgic  pain  which  is  so  common  a  feature  of  zoster. 
The  vesicles  rarely  rupture  when  protected  from  external  irritation,  but  dry  speedily,  in  the 
coui'se  of  a  week,  to  thin,  dark  crusts,  which  fall  and  leave  a  slightly  reddened  surface.  In 
certain  patients,  there  is  a  marked  tendency  of  the  eruption  to  recur  at  intervals. 

The  etiology  of  facial  herpes  is  not  thoroughly  understood.  That  it  is  frequently 
due  to  reflex  nervous  irritation  is  quite  apparent  from  the  fact  of  its  common  occurrence  in 
the  early  stage  of  pneumonia,  and  in  the  urethral  fever  following  internal  urethrotomy. 
The  old  idea  that  its  occurrence  is  a  favorable  prognostic  sign,  appears  to  have  no  scientific 
basis. 

Herpes  progenitalis  consists  in  the  eruption  of  one  or  two  smaU  groups  of  vesicles  on  an 
erythematous  base,  and  is  unaccompanied  by  fever.  In  the  male  the  sheath  of  the  penis 
the  prepuce  or  the  glans  may  be  its  seat,  while  in  the  female  it  may  be  found  u^dou  the  labia 
and  pubes.  When  upon  a  cutaneous  surface,  it  is  usually  recognized  without  difficulty,  but 
upon  the  mucous  sui'face  of  the  genitalia  the  vesicles  become  quickly  macerated,  and  a  mere 
erosion  results.  Herpes  of  the  internal  surface  of  the  prepuce  is  a  quite  common  affection, 
and  one  which  is  frequently  regarded  by  both  patient  and  physician  as  being  of  venereal 
origin.  This  may  be  the  case,  as  the  irritation  of  the  sexual  act  may  evoke  the  eruption, 
especially  in  one  predisposed  to  herpes  of  this  part.  Moreover,  it  may  be  the  result  of  direct 
contagion,  since  the  serum  contained  in  the  vesicles  has  been  successfully  inoculated.  But 
usually  herpes  of  the  prepuce  is  an  innocent  affair.  The  affection  frequently  occurs  in  those 
who  have  never  had  any  venereal  disease,  nor  indulged  in  impure  intercourse.  The  vesicles 
are  usually  accompanied  by  slight  soreness,  and  in  some  cases  by  a  decided  pruritus.  If  the 
part  is  in  a  cleanly  condition,  the  eruption  runs  a  rapid  course,  and  disappears  in  four  or  five 
days.  A  tendency  to  recur  is  noted  in  certain  patients,  as  was  seen  in  the  case  of  herpes  of 
the  face.  Those  who  have  suffered  from  venereal  disease  are  especially  liable  to  recurrent 
attacks,  some  patients  suffering  in  this  way  for  years.  Shortly  after  the  healing  of  a  chan- 
croid, herpes  is  prone  to  occur,  in  which  case  it  is  very  apt  to  be  erroneously  regarded  as  a 
relapse,  or  a  fresh  infection. 

In  private  practice  progenital  herpes  is  usually  observed  in  the  male,  but  the  affection 
is  by  no  means  confined  to  either  sex,  and  among  prostitutes  official  examinations  have  de- 
monstrated its  frequent  occurrence. 

Treatment.  The  treatment  of  facial  herpes  is  mainly  expectant.  A  dusting  powder 
is  the  best  external  application  when  the  eruption  is  extensive.  Spirit  of  camphor,  or  some 
similar  stimulating  liquid  may  be  applied  frequently  to  an  incipient  "  cold  sore  "  in  the  hope 
of  checking  its  development.  If  it  fails,  as  it  generally  does,  cold  cream  may  be  applied  with 
good  effect,  for  the  purpose  of  softening  the  crust  which  forms. 

The  treatment  of  progenital  herpes  is  simple.    Keep  the  part  clean  and  dry.

DISEASES  OF  THE  SKIN— INFLAMMATORY. 


ZOSTER. 
Synonyms — Herpes  Zoster — Shingles. 

The  name  Herpes  lias  been  used  by  dermatological  writers  as  a  generic  term  to  include 
all  eruptions  in  wMcli  groups  of  vesicles  are  present.  This  use  of  the  term  associates  Zoster 
■with  Herpes  of  the  lips  and  prepuce,  and  with  other  rarer  affections,  which  differ  widely  in 
their  clinical  features.  It  is  advisable,  therefore,  to  class  Zoster  as  an  affection  sui  generis. 
The  characteristics  which  serve  to  distinguish  Zoster  from  Herpes  may  be  concisely  stated  as 
follows.  Zoster  is  almost  invariably  unilateral,  and  rarely  occurs  more  than  once  in  a  life- 
time. It  presents  large  isolated  patches  of  tense  vesicles,  seated  on  a  highly  congested  base, 
and  usually  following  the  course  of  a  cutaneous  nerve  for  a  considerable  distance.  It  is  asso- 
ciated with  a  neuralgic  pain  and  a  lancinating  sensation  in  the  affected  skin.  It  usually  runs 
a  regular  course  of  from  two  to  four  weeks  and  occasionally  leaves  cicatrices.  Herpes  is 
usually  bilateral  if  at  all  extensive,  and  may  be  tolerably  symmetrical.  It  occurs  many  times 
in  the  same  patient.  There  is  no  tendency  to  distribution  along  the  course  of  a  single  nerve 
for  any  distance.  The  pain  is  not  of  a  neuralgic  character.  There  is  a  great  variation  in  the 
severity  and  course  of  the  affection,  and  no  scars  are  left. 

Zoster  may  be  defined,  therefore,  as  a  vesicular  eruption,  remarkable  for  its  unilatei-al 
occurrence  and  its  limitation  to  the  cutaneous  distribution  of  one  or  more  nerves.  Though 
not  a  very  common  affection  it  is  one  easily  recognized,  and  is  generally  kno^vn  among  the 
laity  by  the  name  of  ''shingles."  The  eruption  usually  occurs  upon  one  side  of  the  chest 
or  waist,  forming  a  portion  of  a  gii'dle,  from  which  circumstance  is  derived  the  name.  It 
may  also  occur  upon  the  head  or  limbs,  following  in  every  instance  the  course  of  a  nerve.  It 
is  only  in  extremely  rare  cases  that  the  eruption  is  bilateral.  The  sexes  are  about  equally 
liable  to  attacks  and  the  eruption  occurs  at  almost  any  age.  In  children  it  is  annoying  while 
it  lasts,  but  no  neuralgia  is  left  behind,  as  is  often  the  case  in  the  aged. 

The  eruption  usually  begins  after  a  short  febrile  attack,  appearing  in  the  form  of  one  or 
more  patches  of  intense  hypersemia.  A  pricking  or  tingling  sensation  sometimes  calls  the 
patient' s  attention  to  the  part  before  the  vesicles  have  appeared,  but  usually  the  patch  when 
first  seen  is  dotted  with  pearly  vesicles  which  rapidly  attain  the  size  of  hemp-seed.  Fre- 
quently the  vesicles  vary  in  size  upon  different  patches  in  the  same  case,  the  least  developed 
patch  bearing  pin-head  sized  vesicles,  while  those  upon  another  patch  have  reached  the  size 
of  small  peas  and  are  distended  by  a  clear,  yellowish  serum.  The  vesicles  usually  reach  their 
maximum  development  in  four  days,  remain  tense  for  a  day  or  more,  and  then  gradually  fiat- 
ten.  The  inflammatory  base  changes  in  color  from  a  bright  scarlet  to  a  dull  crimson,  and  the 
amber-hued  contents  of  the  vesicles  become  cloudy  and  even  pustular.  In  the  second  week, 
blackish  crusts  or  scabs  form,  which  gradually  fall  during  the  third  or  fourth  week.  The 
eruption  may  fail  to  reach  its  full  development  and  begin  drying  on  thft  second  or  third  day. 
There  are,  strictly  speaking,  no  varieties  of  Zoster,  the  same  characteristics  appearing

whenever  the  eruption  may  be  limited.  Regional  adjectives  are  conveniently  used,  such  as 
Z.  capitis,  Z.  faciei,  Z.  nuchcR,  Z.  brachialis,  Z.  pectoralis,  Z.  ahdominalis,  Z.  lumhalis, 
and  Z.  femoralis.  The  term  Zoster  bullosa  might  be  applied  to  one  of  the  cases  Ulustrated, 
in  which  we  find  an  accidental  elevation  of  the  epidermis  by  a  rapid  exudation  of  serum  and 
a  resulting  confluence  of  the  vesicles. 

The  cause  of  Zoster  is  to  be  found  in  some  abnormal  condition  of  the  nervous  system  in 
general,  or  in  some  injury  or  disease  of  the  nerve  supplying  the  aifected  portion  of  skin. 
The  occurrence  of  the  disease  is  usually  a  surprise,  and  no  conditions  exist  which  would  lead 
one  to  anticipate  an  attack. 

Diagnosis.  A  typical  Zoster  occurring  upon  the  trunk  is  easUy  recognized,  but  when 
the  forehead,  scalp  or  one  of  the  extremities  is  the  seat  of  the  eruption,  a  mistake  is  very 
apt  to  be  made  unless  great  care  is  exercised.  If  the  case  is  seen  when  the  disease  is  at  its 
height,  the  grouping  of  the  vesicles  and  the  disti'ibution  of  patches  along  the  course  of  a 
nerve  serve  as  a  guide.  But  frequently  the  case  is  not  seen  until  the  lesions  have  dried  into 
blackish  crusts  or  have  been  disguised  by  some  local  application,  and  in  such  a  case  the  sud- 
denness of  the  attack,  the  course  of  the  disease  and  the  accompanying  neuralgic  pain  are 
points  which  must  be  taken  as  a  basis  of  diagnosis. 

Treatment.  Zoster  will  always  run  its  course  without  special  treatment.  It  is  useless 
to  attempt  to  abort  the  vesicles  with  nitrate  of  silver  or  blisters.  The  part  should  be  pro- 
tected against  the  friction  of  the  clothing  by  a  soft  linen  cloth,  and  starch  powder  may  be 
dusted  on  to  absorb  the  fluid  when  the  vesicles  rupture.  'When  severe  pain  is  present,  fifty 
centigrams  of  sulphate  of  morphia  may  be  added  to  fifty  grams  of  elastic  colodion  (five 
grains  to  the  ounce)  and  painted  over  the  patches.  The  application  of  the  oil  of  peppermint, 
as  recommended  by  Meredith,  to  lessen  the  pain,  has,  in  my  experience,  only  served  to  aggra- 
vate the  suffering  of  the  patient.  Internally,  the  phosphide  of  zinc,  two  centigi-ams  (one- 
third  of  a  grain)  every  three  hours,  has  been  praised.  As  the  course  of  this  disease  is  varia- 
ble, it  is  difficult  to  judge  of  the  effect  of  an  internal  remedy  except  from  observation  of 
numerous  cases. 


PEMPHIGUS. 

The  term  pemphigus  was  formerly  applied  to  every  eruption  of  bullae  from  whatever 
cause,  and  affections  of  widely  dififerent  nature,  and  variable  prognosis  were  accordingly 
grouped  under  one  head.  Some  of  these  forms  of  bullous  eruption  are  now  recognized  as 
manifestations  of  syphilis  and  leprosy.  Others  are  manifestly  the  direct  effect  of  poisoning 
by  certain  drugs  and  other  ephemeral  causes.  A  peculiar  class  of.  cases  has  been  associated 
with  erythema  multiforme,  and  these  answer  to  the  description  already  given  of  erythema 
bullosum  or  the  hydroa  of  some  writers.  Still  the  term  pemphigus  is  used  in  a  Avide  sense, 
and  further  study  into  the  nature  of  bullous  eruptions  will  be  necessary  before  we  can  limi  r 
the  application  of  the  term  to  a  definite  disease.     At  present  we  must  be  content  to  apply  it 

(93) 


DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

to  various  affections  which,  are  undoubtedly  distinct  in  their  etiology,  but  which  are  charac- 
terized by  the  repeated  outbreak  of  blebs  of  varying  size  and  character. 

The  lesions  of  pemphigus  may  appear  as  tense  hemispherical  bullse  from  the  size  of  a 
pea  to  that  of  an  egg,  or  as  flattened  and  flabby  blisters  of  cii-cular  or  irregular  shape,  often 
involving  considerable  patches  of  epidermis.  They  sometimes  rise  abruptly  from  the  normal 
skin  and  sometimes  are  surrounded  by  a  narrow  red  areola.  The  serous  contents  of  tho 
lesions  are  alkaline  in  reaction  and  contain  albumen.  They  are  at  first  clear  and  translucent, 
but  gradually  become  turbid  or  even  purulent  and  usually  dry  into  thin,  brownish  crusts. 
A  certain  amount  of  fever  may  accompany  the  outbreak  of  the  eruption,  which  may  be 
attended  by  more  or  less  pruritus. 

Three  varieties  of  pemphigus  are  commonly  described.  They  are  acute  pemphigus, 
chronic  pemphigus,  and  a  peculiar  form  known  as  pemphigus  foliaceus.  The  acute  pem- 
phigus, so-called,  is  usually  the  bullous  form  of  erythema  multiforme,  and  has  little  or 
nothing  in  common  %vith  the  chronic  forms  of  the  disease  which  alone  I  am  disposed  to  re- 
gard as  true  pemphigus.  Bullous  eruptions  in  new-born  children  which  have  been  described 
as  pemphigus  neonatorum,  I  have  never  had  the  opportunity  of  observing,  with  the  exception 
of  those  of  an  undoubted  syphilitic  character,  which  tertainly  ought  not  to  be  called  pem- 
phigus. There  remain  then  but  two  forms  of  the  disease  to  be  described,  the  ordinary 
chronic  form  (pemphigus  vrdgaris)  and  the  extraordinary  exfoliative  form  (pemphigus 
foliaceus). 

In  pemphigus  vidgaris  the  lesions  are  scattered  over  a  limited  portion  or  the  whole  extent 
of  the  body.  In  some  cases  the  repeated  outbreaks  are  accompanied  by  fever,  while  in 
others  there  is  no  perceptible  rise  in  temperature  or  any  notable  general  symptoms.  The 
bullse  are  tense  at  the  outset,  but  pressure  or  friction  soon  breaks  the  epidermis  and  allows  a 
portion  of  the  contained  serum  to  escape.  K  the  epidermis  is  forcibly  removed  a  red  and 
moist  surface  is  exposed  which  becomes  quickly  covered  by  a  dry  crust.  This  falls  without 
leaving  any  cicatrix,  but  pigmentation  of  the  spot  frequently  remains  for  months,  and  in 
some  cases  the  whole  skin  becomes  thickened  and  dark  from  the  recurrence  of  the  lesions. 
In  mild  cases  the  skin  remains  for  some  time  free  from  lesions,  but  in  other  cases  a  new  crop 
appears  before  the  last  one  has  had  time  to  run  its  course,  and  the  patient  is  kept  in  constant 
misery  Sometimes  the  bullae  coalesce,  and  upon  removal  of  the  epidermis  large  excoriated 
patches  are  left,  which  become  coated  with  a  diphtheritic  deposit. 

In  pemphigus  foliaceus  we  have  generally  a  severe  case  of  ordinary  pemphigus  in  which 
no  tense  bullse  form,  but  in  which  the  epidermis  becomes  raised  in  masses  by  a  serous  dis- 
charge and  dries  in  large  whitish  flakes,  somewhat  resembling  mealy  pie-crust.  The  diseasH 
usually  progresses  from  bad  to  worse,  the  desquamation  increasing  and  painful  fissures  form- 
ing which  renders  difficult  all  movement  on  the  part  of  the  bed-ridden  patient.  While  in 
young  persons  recovery  may  be  hoped  for  with  proper  treatment,  in  adults  and  especially  in 
the  aged,  a  fatal  result  is  unfortunately  the  usual  termination. 

Diagnosis.    The  recognition  of  true  pemphigus  depends  upon  a  consideration  of  the 

(94) 


PEMPHIGUS. 


rOTTPE,   E.  oiEaSTAOT^ 


ACNE. 

course  of  the  disease  rather  than  upon  the  demonstration  of  a  few  bulljc.  It  is  highly  im- 
portant to  distinguish  the  bullous  variety  of  erythema  multifoi-me  from  pemphigus,  as  the 
prognosis  is  quite  diilerent  in  the  two  affections.  The  distinctive  features  have  already  been 
given.  It  is  not  so  important  to  distinguish  a  severe  case  of  dermatitis  exfoliativa  from 
pemphigus  foliaceus,  and  far  more  difficult  a  task.  Indeed,  there  are  some  cases  where 
differential  diagnosis  is  almost  impossible,  and  the  similarity  or  possible  identity  of  the  two 
diseases  has  already  been  mentioned  in  connection  with  the  former  affection. 

Treatment.  Pemphigus  is  a  disease  which,  resulting  from  an  uncertain  cause,  is  only 
amenable  to  treatment  in  a  slight  degree.  Palliative  measures  will  do  much  to  relieve  the 
suffering  of  the  patient  in  aU  cases,  but  seldom  can  a  cure  of  true  chronic  pemphigus  be  con- 
fidently expected.  Of  internal  remedies  arsenic  has  been  most  highly  praised,  and  certainly 
in  no  other  affection  of  the  skin  can  the  curative  effect  of  this  powerful  drug  be  more  bril- 
liantly displayed.  Still  the  remedy  is  by  no  means  a  specific,  and  in  some  cases  it  fails  en- 
tirely to  check  or  modify  the  recurring  eruptions  of  bullse.  In  one  case  in  which  it  appeared 
to  have  little  or  no  effect  I  found  chaulmoogra  oil  to  be  a  preferable  remedy,  and  from  the 
undoubted  value  of  this  latter  drug  in  leprosy  and  other  chronic  skin  diseases,  I  should  be 
inclined  to  expect  good  results  from  its  use  in  pemphigus. 

The  local  treatment  of  a  case  consists  in  the  constant  application  of  soothing  or  drying 
applications.  From  the  known  property  of  bismuth  to  check  the  discharge  from  a  raw  cuta- 
neous surface,  no  better  local  I'emedy  can  be  found.  At  the  beginning  of  an  attack  or  exa- 
cerbation of  the  disease  when  the  bullae  are  full  and  tense  it  is  advisable  to  prick  them  care- 
fully and  to  cover  the  collapsed  epidermis  with  powdered  bismuth  and  absorbent  cotton. 
When  raw  surfaces  are  present  they  should  be  covered  with  cloths  spread  thickly  with  the 
following  ointment.

In  the  f oliaceous  form  it  is  often  necessary  to  keep  the  patient  oiled  from  head  to  foot  to 
lessen  the  cracking  of  the  inflamed  skin. 

ACNE. 

The  term  Acne  has  been  applied  by  some  writers  to  nearly  aU  affections  of  the  sebaceous 
glands,  whether  inflammatory  or  not,  and  in  this  broad  application  has  included  comedo, 
milium,  seborrhcea  and  moUuscum.  These  affections  depend  upon  pathological  conditions 
which  are  not  essential  elements  of  acne,  which  is  a  purely  inflammatory  affection.  It  is  a 
fact,  however,  that  excessive  secretion  of  the  glands  and  accumulation  of  sebaceous  matter 
in  the  ducts  are  conditions  which  very  frequently  exist  in  connection  with  follicular  inflam- 
mation. 

Acne,  even  in  the  restricted  sense  in  which  the  term  is  now  used,  may  be  regarded  as 

(95) 


DISEASES  OF  THE  SKIN— INFLAMMATORY. 

the  most  common  of  all  cutaneous  affections.  It  maybe  asserted  that  the  majoritj-  of  adults, 
male  or  female,  have  not  passed  through  the  period  of  adolescence  without  having  at  least  a 
mUd  form  of  acne  upon  either  the  face  or  upper  portion  of  the  back.  These  are  the  regions 
upon  which  the  affection  is  most  apt  to  appear.  In  cases  where  the  face  is  affected  in  a 
marked  degree,  the  back,  shoulders  and  breast  may  be  slightly  affected,  or  remain  perfectly 
free  •  while,  on  the  other  hand,  in  cases  where  the  back  is  covered  -n-ith  lesions  of  acne,  the 
face  may  be  nearly  or  wholly  exempt.  The  pustules  of  secondary  syphilis  are  usually  dis- 
seminated over  the  greater  portion  of  the  body,  and  are  sometimes  erroneously  termed  Acne 
syphilitica.  These  are  not  true  acne  pustules,  however,  and  should  be  spoken  of  as  the 
pustular  sj-philide  or  syphiloderm.  Other  eruptions  of  pustules  occm-ring  on  various  por- 
tions of  the  body  result  from  the  ingestion  of  certain  drugs,  or  from  certain  forms  of  external 
irritation.  These  again  are  not  true  acne,  even  though  produced  by  follicular  inflammation. 
They  differ  ia  their  causation,  run  a  different  course,  and  never  demand  the  same  treatment 
as  does  acne.  The  affection  which  has  been  called  Acne  Rosacea  is  also  of  distinct  nature 
and  pathology,  as  will  be  seen  in  the  description  of  that  disease. 

The  lesions  of  acne  are  either  papular,  pustular  or  tubercular  in  character,  and  often 
these  three  varieties  are  present  in  a  given  case.  They  are  scattered  over  certain  limited 
portions,  and  show  no  tendency  to  grouping  or  regularity  of  distribution.  They  vary  from 
a  conical  elevation  of  the  size  of  a  piu-head  to  a  flattened  tumor  as  large  as  a  bean,  having 
the  character  of  a  superficial  abscess.  Their  color  is  a  bright  red  in  patients  with  an  active 
circulation,  but  in  lymphatic  subjects  with  a  thick,  pasty  skin,  the  follicular  inflammation 
is  less  acute  in  character,  and  the  lesions  present  a  duUer  hue. 

For  practical  purposes  the  only  necessary  division  of  acne  is  into  two  varieties,  viz :  Acne 
vulgaris  and  Acne  iridurata.  The  former,  or  common  form  of  the  affection,  is  so  well  known 
as  to  require  no  detailed  description.  It  appears  in  one  patient  upon  the  forehead  or  cheek 
In  the  form  of  a  few  small  red  papules  or  "blotches,"  which  may  disappear  in  a  week  and  re- 
turn when  the  same  dietary  error,  menstrual  irregularity  or  other  exciting  cause  is  repeated.  In 
another  patient  the  papules  resulting  from  simple  follicular  congestion  may  suppurate  and 
form  pustules.  These  may  increase  in  number  through  new  ones  coming  faster  than  the  old 
ones  disappear.  Month  after  month  the  skin  becomes  more  and  more  thickened  by  the 
products  of  inflammation  ;  soaps  and  ointments,  lotions  and  balms,  are  used  by  the  patient  with 
no  perceptible  effect,  and  finally  the  disease  reaches  the  chronic  and  disfiguring  stage  which 
is  represented  in  the  illustration.  In  time  the  disease  disappears,  even  without  treatment, 
as  it  is  rarely  met  with  in  middle  life,  but  often  deep  pits  remain  on  the  site  of  former  pus^ 
tules,  and  resemble  the  marks  left  by  variola.  In  acne  indurata  a  number  of  hard,  subcuta- 
neous nodules  can  be  seen  and  more  readily  felt  upon  the  face  and  neck.  The  skin  over 
these  little  tumors  is  sometimes  unchanged  in  color,  but  as  the  pus  forms  around  the  deep- 
seated  sebaceous  mass  which  causes  the  induration,  the  skin  becomes  reddened,  and  a  small 
abscess  rather  than  a  pustule  is  formed.  This  variety  of  acne  is  most  common  in  IjTnphatio 
subjects.

ACNE. 

Acne  is  an  affection  which  is  never  met  with  in  childhood,  but  which  usually  makes  i;s 
first  appearance  at  the  period  of  puberty,  and  tends  to  disappear  spontaneously  before  the 
age  of  twenty-live.  It  is  only  in  exceptional  cases  that  it  is  met  with  later  in  life.  It  is 
common  in  both  sexes,  and  the  tendency  to  the  eruption  is  frequently  found  to  be  hered- 
itary. ^Vhen  this  is  not  the  case,  it  is  often  difficult  to  explain  why  the  eruption  shoiild 
occur  in  certain  young  people  and  not  in  others.  It  cannot  be  whoUy  attributed  to  indiges- 
tion, sexual  peculiarities  or  local  irritation,  since  similar  conditions  frequently  exist  without 
giving  rise  to  acne,  while  on  the  other  hand,  the  eruption  frequently  occurs  in  those  who  are 
apparently  enjoying  the  most  perfect  health.  Although  the  peculiar  disposition  of  the  seba- 
ceous glands  of  certain  young  people  to  become  inflamed  cannot  be  satisfactorily  accounted 
for,  it  is  certain  that  there  are  many  exciting  causes  of  the  disease,  or  conditions  which  tend 
to  aggravate  it,  and  a  knowledge  of  these  is  of  the  highest  importance  in  the  treatment  of 
a  case. 

External  agencies  have  very  little  to  do  with  the  causation  of  ordinary  acne.  While  it 
is  true  that  the  inunction  of  tar  often  tends  to  plug  the  ducts  of  certain  follicles  and  thereby 
cause  an  inflammation,  there  is  no  reason  to  believe  that  dust  and  dirt  allowed  to  collect  upon 
the  skin  has  any  similar  effect.  Indeed  it  is  notable  that  many  who  have  the  least  acquaint- 
ance with  soap  and  water  present  a  smooth  skin  and  a  fair  complexion  which  many  of  a 
more  cleanly  class  would  give  a  fortune  to  possess.  Too  frequent  bathing,  on  the  other  hand, 
is  perhaps  the  most  frequent  of  the  external  causes  of  acne,  and  those  who  are  unduly  ad- 
dicted to  shower  baths  and  coarse  toweUing  are  most  likely  to  keep  some  of  their  sebaceous 
glands  in  a  state  of  constant  inflammation. 

The  use  of  face  powders  and  cosmetics  of  various  kinds,  however  useless  they  may  be 
for  the  purpose  of  beautifying  the  skin,  have  never  been  the  cause  of  acne,  so  far  as  my 
experience  goes.  Nor  is  a  poor  quality  of  soap  liable  to  cause  acne,  or  injure  the  skin  to 
the  extent  one  might  infer  after  reading  the  advertisements  of  various  manufacturers  of 
this  article.  In  short,  it  may  be  asserted  that  the  causes  of  ordinary  acne,  as  far  as  known, 
are  chiefly,  if  not  entirely,  of  internal  origin. 

The  relation  of  acne  to  the  use  and  abuse  of  the  sexual  functions,  is  a  subject  which  has 
not  been  studied  with  the  requisite  amount  of  caution,  and  many  statements  have  been  made 
by  wi'iters  which  are  not  easily  verified.  While  some  claim  that  masturbation  and  venereal 
excess  is  a  prolific  cause  of  acne,  others  assert  that  continence  in  young  people  is  respon- 
sible for  the  eruption  in  many  cases.  It  is  certain  that  both  views  cannot  be  correct,  and 
my  own  experience  leads  me  to  side  with  those  who  deny  that  either  habit  is  an  etiological 
factor  of  any  great  importance. 

The  aggravation  of  an  existing  acne  in  the  case  of  females  during  menstruation,  or,  as 
more  commonly  happens,  just  before  this  period,  is  a  fact  which  could  hardly  escape  the 
notice  of  the  most  careless  observer.  The  general  vascular  tension  which  accompanies  or 
precedes  this  physiological  function  naturally  induces  an  inflammation  of  the  facial  follicles 

(97) 


I>ISEASES  OF  THE  SKIN.— INFLAMMATORY. 

when  a  predisposition  to  acne  exists,  and  in  most  young  women  suffering  from  acne,  a  fresh 
crop  of  papules  may  be  looked  for  at  this  time.  But  this  happens  in  the  case  of  those  whose 
menstruation  is  normal  in  every  respect,  and  not  with  any  special  frequency  among  those 
who  are  subject  to  dysmenorrhoea.  Acne  is  common  among  women,  too,  who  suffer  from 
uterine  disease,  and  while  it  is  quite  probable  that  the  relation  of  cause  and  effect  may  exist 
in  these  cases,  I  must  confess  that  it  has  yet  to  be  clearly  demonstrated. 

In  irritation  of  the  gastro  intestinal  tract  will  be  found,  I  think,  the  most  common  of 
the  exciting  causes  of  acne.  The  sympathy  existing  between  the  stomach  and  the  face  is  so 
intimate  that  a  hearty  meal,  a  glass  of  wine,  or  a  hot  drink  of  any  kind  will  immediately 
cause  congestion  of  the  latter,  and  when  the  glands  are  obstructed  or  already  intlamed,  an 
aggravation  of  the  acne  is  inevitable.  Acne,  like  urticaria,  is  often  the  direct  effect  of  cer- 
tain articles  of  food,  e.  g.  buckwheat  cakes,  pastry  or  rich  gravies,  a  fact  of  which  the  pa- 
tient soon  becomes  conscious  ;  and  when  no  article  of  diet  appears  to  be  responsible  for  the 
eruption,  the  physician  may  readily  discover  that  gastric  catarrh,  hepatic  torpor  and  consti- 
pation are  important  etiological  factors. 

Diagnosis.  Acne  is  so  frequently  associated  with  comedo  that  some  writers  class  them 
together  as  varieties  of  the  same  disease.  But  in  comedo  we  have  simply  a  distension  of 
the  sebaceous  duct  and  gland  without  inflammation,  which  latter  is  the  essential  element  of 
acne.  This  distinction  is  in  accordance  with  the  classification  we  have  adopted,  but  is  a 
matter  of  little  importance  from  a  practical  point  of  view.  The  association  of  comedos  with 
acne  lesions  often  aids  in  the  diagnosis  of  acne  from  certain  other  affections  which  bear  a 
certain  resemblance,  but  which  do  not  involve  especially  the  sebaceous  glands.  Hence  when- 
ever the  diagnosis  of  a  case  is  doubtful  and  acne  is  suspected,  it  is  highly  important  to  note 
the  condition  of  the  glands  in  the  neighborhood.  For  instance,  a  recent  pustular  syphilide, 
with  a  few  scattered  lesions  on  face  and  shoulders,  might  be  mistaken  for  pustular  acne,  but 
if  upon  examination  it  was  found  that  the  glands  of  the  affected  skin  were  in  a  perfectly  nor- 
mal condition,  neither  inflamed  nor  presenting  numerous  black  specks  at  the  follicular  open- 
ings, the  diagnosis  of  acne  would  necessarily  be  excluded.  On  the  other  hand,  it  would  be 
quite  possible  for  the  lesions  of  acne  and  syphilis  to  co-exist  upon  the  face  and  shoulders  of 
a  patient ;  and,  in  such  a  case,  the  more  important  affection  might  be  overlooked  and  left 
untreated.  The  color  of  the  lesions  might  lead  to  their  recognition  as  separate  affections, 
but  the  most  trustworthy  diagnostic  point  would  be  found  in  the  general  distribution  of 
syphilitic  pustules  over  the  trunk  and  extremities,  and  the  limitation  of  acne  lesions  to  the 
face  and  shoulders. 

Acne  and  rosacea  have  long  been  classed  together  by  ^vriters,  and  only  recently  have 
they  been  sho^vn  to  be  distinct  affections,  the  one  inflammatory  and  the  other  hypertrophic 
in  character.  Nevertheless  they  are  frequently  observed  to  co-exist,  and  in  certain  cases  it 
13  almost  impossible  to  say  whether  the  case  should  be  classed  as  acne  or  as  rosacea,  the  dis- 
\  inctive  characteristics  of  each  affection  being  present.  Typical  cases  may  be  recognized  by 
I  he  following  features  :  while  acne  usually  occurs  in  youth,  affects  the  whole  of  the  face  and 

(98) 


ACNE. 

often  the  chest  and  back,  and  is  generally  associated  with,  comedos,  rosacea  occurs  in  adult 
life,  is  limited  to  the  middle  third  of  the  face,  and  contrasts  strongly  with  the  skin  of  the 
remaining  portion  of  the  face,  the  follicles  of  which  are  always  in  a  normal  condition. 

Teeatmext.  There  are  certain  affections  of  the  skin  in  which  a  routine  plan  of  treat- 
ment is  permissible.  The  remedy  which  cures  one  case  will  produce  the  same  result  in  every 
other  case.  But  acne  is  not  one  of  these  affections.  Indeed,  we  rarely  meet  with  two  suc- 
cessive cases  which  demand  the  same  method  of  treatment,  and  success  in  the  management 
of  this  common  affection  will  usually  depend  upon  a  judicious  adaptation  of  our  therapeutic 
resources  to  the  requirements  of  each  case.  "While  some  patients  demand  nothing  but  local 
measures,  others  cannot  be  cured  without  resorting  to  general  treatment,  and  in  a  certain 
proportion  of  cases,  the  sulphur  and  corrosive  sublimate  lotions  upon  which  so  many  physi- 
cians depend,  will  be  found  of  no  particular  value  whatever,  and  sometimes  prove  positively 
harmful.  My  own  experience  in  the  treatment  of  acne  has  led  me  during  the  past  few  years 
to  rely  more  upon  dietary  and  hygienic  treatment,  and  less  upon  the  application  of  local 
stimulating  applications. 

From  a  therapeutic  standpoint,  cases  of  acne  may  be  conveniently  divided  into  two 
classes.  In  one,  the  sebaceous  element  is  the  most  prominent.  In  the  other,  the  glandular 
secretion  is  not  affected  to  any  great  extent,  but  the  vascular  disturbance  is  the  most  notice- 
able symptom  of  the  case.  In  the  former,  the  evacuation  of  pus  which  may  have  formed, 
and  the  removal  of  the  cheesy  mass  which  distends  the  gland  and  its  duct,  is  the  first  aim  of 
treatment,  and  its  accomplishment  will  subdue  the  peri-glandular  inflammation.  In  the  latter 
no  local  treatment  is  called  for,  unless  it  be  a  soothing  and  palliative  application,  but  our 
chief  aim  miist  be  to  remove  these  varied  causes  which  by  reflex  irritation  tend  to  induce  a 
constant  or  oft  repeated  flushing  of  the  face.  In  these  cases,  the  affected  skin  is  extremely 
irritable,  the  lesions  are  almost  urticarial  in  character  and  will  not  tolerate  the  harsh  local 
measures  which  are  so  valuable  in  a  purely  glandular  form  of  the  disease.  A  careful  dis- 
tinction between  these  two  phases  of  acne  is  of  the  utmost  importance,  and  1  feel  confident 
that  the  hint  which  I  have  given  as  to  the  general  plan  of  treatment  required  by  each  will 
be  worth  far  more  to  the  reader  than  a  host  of  formulae. 

In  the  local  treatment  of  acne,  the  curette  is  without  doubt  the  best  of  all  remedies.  In 
a  well  marked  case,  where  numerous  papules  and  pustules  are  present,  a  curette  of  large  size 
may  be  employed  in  the  manner  suggested  by  Behrend  with  a  most  beneficial  result.  The 
affected  skin  is  scraped  vigorously  with  the  instrument,  and  the  projecting  portion  of  the 
lesions  thereby  cut  or  torn  off.  Pus  is  evacuated,  the  sebaceous  plugs  in  the  follicular  ducts 
are  partially  removed,  and  the  glandular  congestion  is  lessened  by  a  free  hemorrhage.  The 
procedure  leaves  the  face  excoriated  and  unsightly,  but  after  a  few  repetitions  at  intervals  of 
three  or  four  days,  the  acne  lesions  will  have  entirely  disappeared,  and  when  the  redness 
has  gradually  faded,  which  will  usually  happen  after  the  distended  glands  are  emptied,  the 
face  will  present  a  normal  appearance.  A  bad  case  of  acne  cannot  be  improved  so  quickly 
by  any  other  mode  of  treatment. 


DISEASES  OF  THE  SKIN— INFLAMMATORY. 

In  indurated  acne  a  lancet  is  required,  and  a  mde-bladed  one,  with,  shoulder  to  pre- 
vent its  penetrating  too  far,  is  advisable.  The  indurated  nodules  may  contain  pus,  which 
will  escape  after  a  simple  puncture,  but  often  a  hard,  cheesy  mass  is  seated  deep  in  the  skin, 
and  becomes  a  constant  source  of  inflammation.  A  puncture  which  only  allows  a  few  drops 
of  blood,  or  even  a  little  pus,  to  escape,  is  hardly  of  sufficient  benefit  to  warrant  the  pain 
which  it  causes.  The  deep-seated  mass  of  hai-dened  sebum  must  be  removed,  and  to  effect 
this,  it  is  necessary  sometimes  to  make  a  tolerably  free  and  deep  incision.  A  convenient 
instrument  which  I  would  be  loath  to  dispense  with  in  the  treatment  of  acne  consists  of  a 
tubular  handle  \vith  a  small  curette  screwed  upon  one  end  and  an  acne  lancet  upon  the  other. 
When  not  in  use  the  curette  and  lance  are  inside  the  handle,  so  that  the  instrument  can  be 
carried  in  the  vest  pocket.  In  evacuating  the  inspissated  contents  of  the  glands,  when  they 
axe  not  inflamed,  but  project  as  little  white  granular  tumors  (acne  albida),  the  epidermis  may 
be  lightly  pricked  with  the  lancet,  and  the  cheesy  mass  extruded  by  pressure  of  the  point  of 
the  curette  as  explained  in  speaking  of  the  removal  of  comedos.     (Page  14.) 

Soap  frictions  are  of  value  in  those  cases  of  acne  where  the  lesions  are  small  and  numer- 
ous. When  they  are  few  and  far  between,  it  is  unnecessary  to  inflame  the  whole  skin  of  the 
part  treated,  but  preferable  to  use  the  curette.  The  officinal  green  soap,  or  ordinary  soft 
soap,  or  the  Tinctura  saponis  viridis  may  be  used  in  the  following  manner  :  Before  going  to 
bed,  a  piece  of  flannel  or  lint  is  first  dipped  in  hot  water,  and  then  upon  this  the  soap  is 
applied  to  the  face.  The  skin  should  be  scrubbed  vigorously  for  five  or  ten  minutes,  and 
the  face  then  bathed  in  hot  water,  and  nothing  of  a  fatty  nature  applied.  In  a  few  days  the 
skin  usually  becomes  red  and  painful,  and  the  patient  often  objects  to  the  treatment,  as  it 
does  not  improve  the  appearance  of  the  face.  It  is  important,  however,  to  continue  the 
frictions  until  a  considerable  degree  of  artificial  inflammation  is  excited,  as  will  be  seen  by 
a  tendency  of  the  epidermis  to  peel,  and  in  some  cases  it  will  be  necessary  to  have  the  pa- 
tient leave  the  soap  upon  the  sldn  all  night.  When  the  skin  is  sufficiently  inflamed,  the 
soap  frictions  should  be  discontinued,  and  a  soothing  ointment  applied  to  the  face.  In 
a  few  days  the  acute  inflammation  will  have  subsided,  and  the  skin  will  appear  much 
smoother  and  softer  than  before  the  treatment  began.  In  obstinate  cases,  it  is  often  neces- 
sary to  return  to  the  use  of  the  soap  several  times  before  the  skin  will  present  a  natural  ap- 
pearance, each  series  of  frictions  removing  many  of  the  comedos  and  acne  lesions.  Even 
when  the  skin  has  become  quite  smooth  and  free  from  acne,  a  certain  amount  of  redness  will 
often  remain,  which  can  be  treated  by  one  of  the  numerous  sulphur  ointments  or  lotions  of 
which  the  f  ollo^ving  are  samples.

The  local  use  of  sulphur  is  often  beneficial  in  acne,  as  it  serves  to  stimulate  the  circula- 
tion, lessen  the  passive  hypersemia  and  thus  to  bleach  the  complexion,  but  the  remedy  \vill 
not  reach  the  cause  of  the  congestion  nor  have  any  effect  in  emptying  the  contents  of  the 
torpid  glands,  and  hence  the  common  practice  of  depending  wholly  upon  some  sulphur  ap- 
plication for  the  cure  of  acne  is  manifestly  absurd  and  is  usually  the  secret  of  the  frequent 
failure  in  treatment.  In  mild  cases  of  acne  among  young  women  the  precipitated  sulphur 
may  be  used  as  a  face  powder,  but  the  benefit  derived  from  its  use  in  this  manner  is  slight  in 
comparison  with  what  has  been  claimed  for  it.  In  chronic  cases  with  much  inflammatory 
thickening  of  the  skin  and  little  or  no  tendency  to  suppuration  the  iodide  of  sulphur  oint- 
ment of  varying  strength  will  be  found  serviceable.  In  prescribing  sulphur  as  an  applica- 
tion to  the  face  in  any  form  the  physician  must  always  bear  in  mind  that  its  chemical  com- 
bination with  lead  or  mercuiy  in  the  follicles  of  the  skin  wiU  produce  a  multitude  of  black 
specks  which  often  look  worse  than  the  red  blotches  of  acne.  The  patient  should  be 
questioned  as  to  whether  any  lead  or  mercurial  applications  have  been  recently  made  to  the 
face,  and  if  so,  the  skin  must  be  scrubbed  thoroughly  mth  soap  and  hot  water  before  it  wiU 
be  safe  to  prescribe  the  use  of  sulphur.  Mercurial  applications  are  of  comparatively  little 
benefit  in  most  cases  of  acne,  although  corrosive  sublimate  is  an  ingredient  of  many  of  the 
cosmetic  lotions  intended  to  beautify  the  skin  and  which  are  often  recommended  in  the 
treatment  of  acne.  When  it  is  necessary  to  give  some  pleasant  local  application  to  satisfy 
the  patient  while  the  indigestion  or  other  cause  of  the  acne  is  being  gradually  removed,  one 
of  the  following  may  be  ordered.

While  local  treatment  is  of  great  value  in  many  cases  of  acne  there  are  some  in  which 
it  is  capable  of  producing  very  little  benefit,  and  in  a  great  majority  of  cases  general  treat- 
ment is  of  the  utmost  importance.  In  that  large  class  of  cases  of  irritable  acne  occurring  in 
women  where  the  vascular  disturbance  is  a  more  prominent  feature  of  the  affection  than  any 
anomaly  of  the  sebaceous  secretion,  my  experience  has  led  me  to  discard  local  treatment  and 
to  depend  almost  entirely  upon  dieting  and  hygienic  regimen.

DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

The  effect  of  a  modified  or  restricted  diet  is  usually  more  marked  in  acne  than  in  almost 
any  other  affection  of  the  skin.  There  is  usually  some  form  of  iadigestion  at  the  root  of  the 
trouble;  and  although  many  confirmed  dyspeptics  have  a  fair  complexion,  and  many  acne 
patients  scorn  the  imputation  that  there  is  anything  the  matter  with  their  digestion,  I  must 
say  that  I  constantly  find  that  a  change  in  the  quantity  and  quality  of  their  food  Avill  pro- 
duce an  immediate  amelioration  of  the  eruption  and  notably  improve  the  general  health. 
Tea  and  coffee,  as  well  as  wine  and  beer,  must  be  forbidden.  The  diet  must  be  of  the  plainest 
and  most  nutritious  kind,  and  not  only  should  highly-seasoned  food,  rich  gravies,  pastry, 
cake  and  candy  be  excluded  from  the  dietary  list,  but  every  article  of  food,  the  propriety  of 
eating  which  is  open  to  suspicion,  should  be  resolutely  put  aside.  The  meals  should  be  taken 
regularly  and  deliberately.  Little  if  any  water  should  be  drurk  at  meal  time,  but  a  large 
amount  can  be  taken  with  benefit  about  two  hours  after  each  meal,  when  the  digestive  pro- 
cess is  nearly  completed.  This  will  often  relieve  the  habitual  constipation  and  frequent 
headaches  from  which  acne  patients  are  disposed  to  suffer.  In  many  cases  the  stomach 
needs  a  rest,  and  it  is  sometimes  advisable  to  allow  but  one  full  meal  daUy,  the  breakfast  and 
lunch  (or  supper)  consisting  of  merely  a  slice  of  brown  bread,  with  a  little  fruit  or  glass  or 
two  of  milk,  if  this  is  found  to  agree  with  the  patient.  An  increased  amount  of  exercise 
should  be  prescribed  with  the  restricted  diet.  Indeed  the  rule  to  eat  less  and  exercise  more 
will  be  found  to  strike  at  the  root  of  acne  and  of-  many  other  affections  of  the  skin. 

The  Turkish  bath  is  one  of  the  most  valuable  remedies  in  the  general  treatment  of  acne. 
An  imperfect  circulation,  with  a  tendency  to  cold  and  clammy  hands  and  feet  is  frequently 
noted  in  connection  with  the  eruption,  and  the  bath  taken  twice  or  three  times  every  week 
will  not  only  improve  the  affected  skin  but  increase  the  tone  of  the  whole  system. 

Of  internal  remedies  there  are  two  which  deserve  a  special  mention.  These  are  calx 
sulphurata  and  ergot.  The  former,  by  virtue  of  its  influence  upon  the  suppurative  process 
is  often  of  great  value  in  certain  cases  of  pustular  acne,  if  given  in  a  proper  dose.  The 
failures  in  the  use  of  this  drug  in  acne  have  generally  resulted  from  its  employment  in  too 
large  a  dose,  a  grain  or  two  daUy  being  frequently  given.  My  plan  is  to  order  one-tenth  of 
a  grain  every  two  hours  in  a  case  of  chronic,  indurated  acne,  and  to  give  one-twentieth,  one- 
fifteenth  or  even  less  at  a  dose  in  the  more  acute  and  irritable  cases. 

Ergot  may  be  given,  as  recommended  by  Denslow,  in  the  form  of  a  fluid  extract,  a  half 
drachm  three  times  daUy,  or  three  grain  pills  of  ergotine  may  be  employed.  Any  digestive 
error  should  be  corrected  by  suitable  remedies  before  the  ergot  treatment  is  begun.  I  have 
seen  some  brilliant  results  from  the  use  of  this  drug,  and  have  seen  it  productive  of  no 
beneficial  result  whatever  in  other  cases.  It  appears  to  act  best  in  the  case  of  lymphatic 
subjects,  with  a  thick,  pasty  skin  and  sluggish  circulation,  which  fact  woiild  seem  to  corrobo 
rate  Denslow' s  view  that  the  ergot  cures  the  acne  by  virtue  of  its  action  in  contracting  the 
arrectores  pilorum  or  little  muscles  which  run  beneath  the  sebaceous  glands,  and  /.ot  aa 
(jthers  have  supposed,  through  its  action  upon  the  capillary  vessels.

SYCOSIS. 
SYCOSIS. 

Synonym — Barber's  Itch. 

Sycosis  is  an  inflammatory  disease  of  the  hair  follicles,  usually  affecting  the  bearded 
portion  of  the  face.  It  is  characterized  by  tenderness  and  swelling  of  the  skin  and  the 
development  of  deep-seated  nodules  and  superficial  pustules,  each  one  of  which  is  usually 
perforated  by  a  hair.  The  affection  is  allied  to  acne  and  differs  from  it  in  its  anatomical 
seat,  the  inflammatory  process  taking  place  in  and  around  the  hair  follicles  instead  of  the 
sebaceous  glands. 

The  affection  often  begins  suddenly  Avith  a  heat  and  tension  in  the  part,  and  the  primary 
starting  point  of  the  inflammation,  according  to  Robinson,  is  in  the  connective  tissue  around 
the  hair  sac,  thus  constituting  a  perifolliculitis.  The  follicle  becomes  quickly  involved 
and  the  pus  reaches  the  surface  of  the  skin  between  the  hair  and  the  follicular  wall.  The 
lesions  may  be  scattered  over  the  cheek  or  chin,  but  since  inflammation  of  one  follicle  is  very 
apt  to  extend  to  those  in  the  vicinity,  the  eruption  is  usually  found  in  ill-defined  patches 
where  the  lesions  are  crowded.  It  is  rare  for  the  whole  bearded  portion  of  the  face  to  be 
involved,  and  this  never  occui's  except  in  extremely  chronic  cases.  Occasionally  the  eye- 
brows and  eye-lashes,  the  scalp,  neck  and  pubic  region  are  affected. 

The  course  of  sycosis  is  variable.  In  some  mild  cases  it  may  tend  to  a  spontaneous  cure, 
but  generally  it  becomes  a  chronic  and  most  annoying  affection.  When  the  follicular  suppu- 
ration has  been  profuse  the  matrix  of  the  hair  is  often  destroyed  and  permanent  baldness  of 
the  affected  part  is  the  result. 

Sycosis  is  a  disease  of  adult  males.  It  often  attacks  the  robust,  although  its  worst  phases 
are  generally  observed  among  those  who  are  weak  or  in  poor  condition.  It  is  seldom  met 
with  upon  the  face  of  those  who  are  addicted  to  the  daUy  use  of  a  razor.  The  proximate 
cause  has  been  supposed  to  be  the  premature  gro^vth  of  new  hairs  in  the  follicles,  the  small- 
ness  of  the  f oUicle  in  proportion  to  the  size  of  the  hair,  the  irritation  resulting  from  the  use 
of  a  dull  razor,  etc.,  etc.  The  etiology  is  generally  obscure  and  does  not  throw  much  light 
upon  the  treatment  of  cases. 

Diagnosis.  It  is  sometimes  difficult  to  distinguish  sycosis  from  trichophytosis  barbae, 
which,  in  some  instances,  assumes  a  nodose  foi-m  and  presents  a  true  folliculitis.  This  is  de- 
scribed by  some  writers  as  a  distinct  affection  from  ordinary  ringworm,  and  is  called  sycosis 
parisitaria.  In  this  affection  there  is  usually  a  considerable  amount  of  subcutaneous  inflam- 
mation, and  the  affected  skin  often  swells  up  into  a  fig-like  tumor,  which,  subjected  to  pres- 
sure, oozes  pus  at  every  follicular  opening.  In  the  vicinity  and  upon  other  portions  of  the 
body  the  typical  scaly  patches  of  ordinary  ringwonn  are  often  present  and  thereby  reveal 
the  parasitic  natui-e  of  the  affection.  The  history  of  contagion  and  the  friability  of  the  hair 
will  sometimes  lead  to  a  correct  diagnosis  of  the  cause  of  the  folliculitis,  but  in  aU  cases  of  a 
doubtful  character  the  microscope  must  be  relied  upon  to  determine  the  presence  or  absence 
of  the  trichophytic  spores. 

(103) 


DISEASES  OF  THE  SKIN— INFLAMMATORY. 

Sycosis  bears  a  strong  resemblance  to  a  pustular  eczema,  and  Pifiard  and  some  otlier 
excellent  dermatologists  deny  that  the  affection  is  distinct  in  its  nature.  While  it  is  true 
that  eczema  often  attacks  the  bearded  portion  of  the  face  and  in  some  instances  does  not 
confine  itself  to  its  favorite  anatomical  seat  in  the  mucous  layer  of  the  epidermis,  but  also 
involves  the  follicles,  and  thus  induces  a  folliculitis  or  secondary  sycosis,  there  yet  remain 
many  cases  in  which  there  is  simply  a  follicular  inflammation  Avithout  any  tendency  whatever 
to  that  catarrhal  inflammation  of  the  skin,  which  is  the  essential  element  of  eczema. 

In  eczema  of  the  beard  the  eruption  is  apt  to  extend  upon  the  hairless  parts,  and  especi- 
ally to  appear  about  the  ears.  The  hairs  are  never  loosened  however  intense  the  cutaneous 
inflammation  may  be,  and  there  is  frequently  a  weeping  surface.  In  sycosis  the  eruption  is 
invariably  restricted  to  the  haiiy  parts.  The  suppuration  \vithin  the  foUicles  produce  a  loos- 
ening of  the  hair  and  often  a  spontaneous  depilation,  and  however  thick  the  pustules  and 
crusts  may  appear  upon  the  surface  of  the  skin,  there  is  never  any  superficial  serous  exuda- 
tion such  as  is  observed  in  eczema. 

A  tubercular  syphUide  of  the  bearded  portion  of  the  face  might  be  mistaken  for  sycosis 
on  account  of  the  presence  of  nodules  and  crusts,  but  the  grouped  and  circular  character  of 
the  tubercles,  and  the  complete  absence  of  pain  or  a  burning  sensation  would  point  to  syphilis 
rather  than  to  sycosis. 

Treatment.  Although  sycosis  often  proves  to  be  a  chronic  and  rebellious  affection 
there  are  few  if  any  cases  in  which  a  judicious  plan  of  treatment  ^viU  not  effect  a  cure  in  a 
reasonably  short  time.  Local  measures  are  of  chief  value,  although  in  every  case  sucli  gen- 
eral treatment  as  will  conduce  to  an  antiphlogistic  effect  upon  the  skin  ought  not  to  be  neg- 
lected. Restricted  diet  and  mineral  waters  will  usually  do  much  to  relieve  the  congestion  of 
the  skin  and  thereby  lessen  the  pain  which  in  some  cases  is  a  prominent  feature  of  the 
disease. 

At  the  beginning  of  our  treatment  it  is  always  advisable  to  have  the  face  closely  shaven 
if  the  patient  Avill  submit  to  this  procedure.  If  the  skin  is  too  tender  to  allow  the  use  of  a 
sharp  razor,  the  hairs  may  be  clipped  as  short  as  possible  and  a  hot  poultice  applied.  The 
next  step  is  to  remove  by  means  of  the  epilating  forceps  all  hairs  which  are  loosened  by  the 
follicular  suppuration  and  as  many  more  as  will  yield  to  the  slightest  traction.  In  some  cases 
this  is  an  extremely  painful  operation,  and  I  have  known  strong  men  to  wince  and  shrink  at 
every  approach  of  the  forceps  to  the  face,  and  after  the  removal  of  a  few  hairs  declare  that 
they  could  not  possibly  bear  to  have  more  removed  that  day.  The  effect  of  the  removal  of  a 
few  hairs  which  act  like  thorns  in  the  inflamed  flesh,  is  always  notably  beneficial,  and  by  per- 
sistence in  this  method  of  treatment  a  relief  of  the  pain  and  swelling  is  obtained  which  no 
soothing  ointment  or  lotion  could  possibly  produce.  When  all  the  loose  hairs  are  removed 
the  oxide  of  zinc  ointment  or  the  following  may  be  applied  in  place  of  the  poultice.

PORRIOO. 

Frora  week  to  week  such  hairs  may  now  be  epilated  as  appear  surrounded  by  a  papule, 
and  soon  the  tendency  to  pustulation  will  be  found  to  have  ceased  entirely.  The  skin  often 
remains  somewhat  thickened  and  red  for  a  month  or  two,  and  when  the  epilation  is  no  longer 
deemed  necessary  the  affected  hairs  may  be  rubbed  nightly  with  a  five  per  cent,  oleate  of 
mercury  or  the  white  precipitate  ointment. 

The  progress  of  a  disease  towards  a  cure  is  not  always  uniform,  and  frequently  a  relapse 
occurs  -with  a  sudden  increase  of  pain  and  swelling  in  the  affected  skin.  In  such  a  case  it  is 
necessary  to  suspend  any  stimulating  plan  of  treatment  for  a  few  days,  and  often  advisable 
to  prescribe  pugation  and  poulticing  until  the  acute  inflammation  has  subsided. 

PORRIGO. 

Synonym — Impetigo  contagiosa. 

The  name  Porrigo  has  been  applied  by  the  older  writers  on  skin  diseases  to  so  many  pus- 
tular, as  well  as  non-pustular  affections  of  widely  different  nature,  that,  at  the  present  day 
it  is  scarcely  able  to  retain  a  position  in  dermatological  nomenclature.  As  there  exists,  how- 
ever, a  contagious  pustular  affection  of  the  skin,  which  is  neither  eczematous  nor  unmistaka- 
bly parasitic,  and  to  which  no  settled  name  is  attached,  I  am  disposed  to  follow  the  example 
of  Startin,  Nayler,  and  Hutchinson,  and  to  apply  to  it  the  old  and  misused  term,  Porrigo. 

The  affection  is  an  acute  one,  and  is  characterized  by  a  rapid  development  of  one  or 
many  flat,  vesico-pustules,  which  spring  from  an  apparently  normal  skin.  These  are  quite 
superficial,  tend  to  enlarge  peripherally  though  remaining  flattened,  and  usually  attain  the 
size  of  a  ten-cent  piece.  The  crusts  which  form  are  thick,  friable,  varying  from  a  straw  color 
to  a  greenish-yellow,  or  brownish  hue,  and  often  presenting  a  central  depression,  like  a  vaccine 
crust.  They  are  lightly  adherent,  and  when  forcibly  removed,  expose  a  raw,  purulent  sur- 
face, but  no  deep  ulcer.  When  allowed  to  dry  and  fall,  a  thin,  reddened  epidermis  remains 
for  a  short  time,  and  disappears  vrithout  leaving  a  scar.  The  chief  peculiarity  of  the  pus- 
tules is  their  contagious  character.  When  occurring,  as  they  frequently  do  in  connection 
with  phtheiriasis,  it  is  quite  apparent  that  they  tend  to  develop  whenever  the  skin  is  exco- 
riated, and  it  appears  quite  probable  that  the  pus  partakes  of  an  infectious  nature,  and  is 
carried  from  one  point  to  another  by  the  finger-nails.  New  pustules  may  be  readily  pro  • 
duced  by  intentional  auto-inoculation.  The  affection  is  quite  common  among  children,  but 
it  also  attacks  adults.  Frequently  several  members  of  a  household  are  successively  affected, 
and  epidemics  have  been  reported  to  occur.  The  pustules  are  most  frequently  met  with  upon 
the  scalp  and  face.  The  trunk  and  extremities,  and  particularly  the  fingers,  may  also  be  its 
seat.  It  occasionally  develops  when  no  apparent  cause  exists.  Local  irritation  of  some 
sort,  however,  can  generally  be  detected,  and  to  the  irritating  preseiice  of  pediculi  the  affec- 
tion is  frequently  attributable.  A  fungus  has  been  described  as  existing  in  the  crusts,  but  it 
has  not  been  proven  to  be  the  essential  cause  of  the  affection. 

A  bullous  form  of  the  disease  I  have  recently  had  the  opportunity  of  observing  at  the 

(105) 


DIS£A  SiiS  OF  TEE  SKIN—INFLAMMA  TOR  Y. 

I^urseiy  and  CMld's  Hospital,  tlirongli  the  kindness  of  Dr.  E.  L.  Partridge.  The  eruption 
might  have  passed  for  an  acute  pemphigus,  but  the  typical  character  of  the  lesions  in  one 
case  and  the  strong  probability  of  it  having  affected  three  other  children  through  contagion, 
appeared  to  me  sufficient  to  establish  the  diagnosis.  These  latter  children  were  thin  and 
weakly  and  the  eruption  was  mostly  confined  to  the  neck  and  breast.  Bullae  as  large  as  a 
walnut,  though  not  tense,  formed  in  numbers.  The  whole  neck  became  almost  denuded  of 
epidermis,  leaving  a  dry  reddened  patch  of  skin  with  a  peeling  border.  In  only  one  of  these 
cases  was  the  eruption  accompanied  with  fever. 

Diagnosis.  The  diagnosis  is  easy,  although  some  confusion  aiises  from  the  varying 
descriptions  of  Impetigo  and  Eczema  impetiginosum  which  are  found  in  the  text  books. 
The  term  Impetigo  is  regarded  by  most  recent  \vriters  as  a  synonym  of  pustular  eczema,  "an 
eczema,"  according  to  Tilbury  Fox,  "  occurring  in  a  pyogenic  habit  of  body."  The  Impetigo 
contagiosa,  described  by  this  late  writer,  appears  to  me  to  be  simply  a  form  of  Porrigo  which 
occurs  largely  among  children,  and  is  usually  accompanied  at  the  outset  by  slight  febrile 
symptoms.  Such  cases  I  have  had  repeated  opportunities  of  studying,  and  have  verified  the 
admirable  description  of  the  eminent  English  author.  I  see  no  reason,  however,  why  the 
name  which  is  applied  to  these  cases  (be  it  Porrigo  or  Impetigo  contagiosa),  should  not  also 
be  applied  to  an  eruption  of  isolated,  contagious,  vesico-pustules  in  adults,  although  unac 
companied  by  febrile  symptoms,  and  occurring  as  a  complication  of  phtheiriasis. 

Treatment.  To  cure  the  affection  it  is  first  nesessary  to  remove  the  crusts,  which  can 
be  done  without  violence  after  the  application  of  a  poultice  or  folded  cloth  Avrung  out  of 
hot  water.  A  five  per  cent,  ointment  of  carbolic  acid  may  then  be  applied  to  the  affected 
skin  for  a  few  days.  In  many  cases  the  lesions  tend  to  run  a  definite  course  of  from  one  to 
three  weeks,  and  sometimes  they  do  not  yield  to  treatment  as  readily  as  their  superficial 
character  would  lead  one  to  expect. 

ERYSIPELAS. 

Erysipelas  is  an  infectious  disease  characterized  by  an  eruption  which,  starting  at  a 
given  point,  gradually  involves  succeeding  portions  of  skin.  This  is  always  accompanied  by 
fever,  and  usually  a  chill,  or  succession  of  chills,  \vith  general  lassitude  for  several  days,  pre- 
cedes the  eruption.  When  erysipelas  occurs  spontaneously,  some  portion  of  the  face,  and 
usually  the  bridge  of  the  nose  is  the  starting  point.  The  eruption  begins  as  a  red  and  tender 
lump,  upon  which  pressure  of  the  finger  leaves  a  temporary  yellowish  pit.  It  spreads  grad 
uaUy,  becoming  deeper  in  hue,  and  the  advancing  border  of  the  patch  is  always  abruptly 
raised,  like  a  wall,  above  the  healthy  skin. 

In  connection  with  the  fever  and  cutaneous  inflammation,  some  of  the  internal  serous 
membranes  may  be  inflamed.  In  every  severe  case  of  erysipelas  of  the  face  and  scalp  there 
is  usually  more  or  less  swelling  of  the  throat,  and  a  fatal  result  is  not  unfrequently  the  result 
of  ODdema  of  the  glottis,  or  cerebral  congestion.  On  the  other  hand,  the  disease  sometimes 
produces  an  unexpectedly  favorable  result,  and  patches  of  erythematous  lupus  and  chronic 

(106) 


EBTSIPELAS. 

eczema,  or  leg  ulcers,  may  disappear  entirely  or  be  greatly  benefited  in  consequence  of  an 
attack  of  erysipelas.  When  tlie  affection  recurs  frequently  in  the  same  locality,  as  it  some- 
times shows  a  disposition  to  do,  a  chronic  csdema  ensues,  which  in  time  leads  to  a  marked 
thickening  and  induration  of  the  skin  as  in  elephantiasis. 

The  cause  of  erysipelas  is,  without  doubt,  an  infectious  germ  which  usually  finds  an  en- 
trance into  the  system  through  some  abraded  or  raw  surface,  such  as  an  idcer  or  fresh  wound. 
Even  when  it  commences  upon  the  unbroken  skin  of  the  face,  without  any  known  exposure 
to  contagion,  it  is  quite  possible  that  some  stray  germ  of  the  disease  has  been  absorbed 
through  some  trifling  lesion  of  the  nasal  mucous  membrane. 

Erysipelas  may  begin  within  the  nose  or  upon  the  mucous  membrane  of  the  pharynx 
and  by  extension  through  the  nasal  passages  reach  the  skin.  It  frequently  has  its  starting 
point  at  the  umbilicus  of  the  new  bom  child,  and  in  such  a  case  it  sometimes  extends  over 
the  whole  body  and  terminates  fatally.  Its  occurrence  after  vaccination  is  not  uncommon, 
and  the  tendency  which  it  frequently  manifests  in  hospitals  to  occur  in  epidemic  foi-m  and  to 
attack  every  raw  surface  naturally  renders  it  the  dreaded  foe  of  surgeons. 

The  lids  of  one  or  both  eyes  usually  become  (Edematous  and  tightly  closed.  The  mouth 
can  scarcely  be  opened  when  the  lips  are  involved,  and  in  some  cases  the  features  become  so 
changed  in  appearance  that  the  patient  would  scarcely  be  recognized.  The  swelling  of  the 
ear  usually  prevents  the  sufferer  from  lying  upon  that  side,  and  when  the  patch  has  ex. 
tended  over  the  scalp,  the  pain  from  pressure  of  the  pillow  is  apt  to  be  severe  and  annoying. 
Occasionally  the  eruption  extends  down  upon  the  back. 

In  most  cases,  the  swelling  of  the  skin  and  the  accompanying  pain  lessen  in  a  few  days^ 
60  that  the  parts  first  attacked  become  smooth,  or  merely  covered  with  a  desquamating  epi- 
dermis, while  the  active  inflammatory  pi-ocess  is  invading  new  territory.  The  surface  of  the 
swollen  skin  is  frequently  the  seat  of  vesicles,  or  bullse,  which  dry  and  form  crusts  as  the 
Bwelling  subsides.     Sometimes,  in  old  persons,  gangrene  of  the  skin  occui's. 

Diagnosis.  Erysipelas  may  be  readily  distinguished  from  erythema,  eczema  and  other 
inflammatory  skin  affections  by  the  general  febrile  symptoms  which  accompany  the  eruption, 
the  pain  and  swelling  of  the  affected  part  and  the  abrupt  margin  of  the  advancing  patch. 
There  is  a  cellulitis,  however,  which  is  erysipelatoid  in  character  and  which  is  often  difficult 
to  distinguish  from  the  true  disease. 

Treatment.  An  appreciation  of  the  infectious  nature  of  erysipelas  ought  to  be  of  great 
service  in  its  prophylaxis.  Although  many  cases  appear  to  be  spontaneous,  and  cannot 
possibly  be  avoided,  there  are  some  which  are  the  direct  result  of  carelessness,  and  for  which 
the  physician  or  surgeon  should  be  held  responsible.  Surgical  instruments,  and  especially 
the  vaccine  lancet,  should  be  thoroughly  cleaned  by  some  disinfectant  fluid  after  every  ope- 
ration, and  every  case  occurring  in  hospital  ought  to  be  isolated  at  the  earliest  possible  mo- 
ment. In  the  treatment  of  every  case,  both  local  and  general  measures  are  called  for.  Tlie

DISEASES  OF  THE  SKIN.— INFLAMMATORY. 

boring  healthy  skin  -with  iodine  or  nitrate  of  silver,  is  now  obsolete,  and  our  chief  aim  should 
be  to  relieve  the  pain  and  swelling.  This  can  be  best  effected  by  the  application  of  a  lead 
and  opium  lotion  or  some  soothing  ointment.  Painting  the  affected  skin  with  collodion  is 
apt  to  occasion  more  discomfort  than  benefit,  and  is  inferior  to  the  use  of  compresses  dipped 
in  hot  water  containing  carbolic  acid.  ^Yhen  the  fever  is  of  high  grade,  full  doses  of  quinine 
are  indicated,  and  if  the  stomach  does  not  tolerate  the  drug,  it  may  be  administered  in  the 
form  of  a  suppository.  Iron  and  quinine  should  be  given  steadily  until  convalescence  sets  in. 
Carbonate  of  ammonia  every  two  hours  has  been  employed  successfully. 

FURUNCULUS. 

Synonym — Boil. 

A  furuncle  is  a  localized  inflammation  of  the  skin  and  subcutaneous  tissue,  producing  a 
reddened,  conical  and  painful  tumor.  Its  essential  feature  is  the  formation  of  a  central 
Blough,  in  which  respect  it  differs  from  simple  follicular  intlammation  or  a  superficial  abscess. 
It  begins  as  a  small  pointed  papule,  which  in  a  few  days  has  usually  increased  to  the  size  of 
a  large  pea  or  marble.  The  skin  is  tense  and  red,  and  at  the  summit  of  the  conical  tumor  a 
small  grayish  speck  is  apparent.  This  rapidly  becomes  pustular,  and  soon  an  opening  is 
seen  through  which  the  pus  formed  within  the  tumor,  together  with  the  "core"  or  slough- 
ing tissue  may  be  spontaneously  evacuated. 

BoUs  are  usually  multiple,  and  develop  successively,  or  in  repeated  crops.  The  individ- 
ual tumor  runs  a  limited  course  of  from  one  to  two  weeks,  but  the  tendency  to  the  occur- 
rence of  others  in  its  place  often  persists  for  several  months.  The  neck  is  the  favorite  seat 
of  the  lesions,  but  there  is  scarcely  any  portion  of  the  body  which  is  exempt  fro?n  the  loca- 
tion of  a  boU,  and  no  spot  seems  to  the  patient  so  undesirable  to  have  it  as  the  very  one  upon 
which  it  has  located. 

The  cause  of  boUs  is  not  always  apparent.  WhUe  they  are  not  infrequent  among  poorly 
nourished  children,  and  adults  whose  general  condition  is  impaired  by  dissipation  of  various 
sorts  and  by  overwork,  th.ey  sometimes  attack  those  who  are  robust  and  apparently  in  ordi- 
nary health.  Strangely  enough,  the  affection  is  quite  apt  to  be  observed  in  the  case  of  ath- 
letes who  are  undergoing  a  course  of  training.  As  a  direct  result  of  diabetes,  boils  are  fre- 
quently noted,  and  their  repeated  occurrence  should  lead  to  an  examination  of  the  urine. 

Diagnosis.  A  typical  furuncle  is  net  apt  to  be  mistaken  for  any  other  disease  of  the 
ekin,  but  the  affection  often  runs  an  abortive  course,  and  no  central  slough  is  formed.  These 
so-called  "blind  l^oils,"  are  often  met  with  in  connection  with  other  inflammatory  eruptions, 
and  as  described  by  Bronson,  are  a  frequent  accompaniment  of  miliaria. 

Tkeatme>"t.  Boils  may  sometimes  be  arrested  in  their  incipient  stage  by  the  adminis- 
tration of  calx  sulphurata  and  the  other  alkaline  sulphides  which,  according  to  Ringer  and 
the  experience  of  many  others,  exert  a  marked  influence  upon  the  suppurative  process  in 
various  affections.     ^Vhen  a  boU  is  at  its  height,  one-tenth  of  a  grain  of  the  drug  given  three 

(108) 


CARBUNCULUS. 

or  four  times  daily,  will  hasten  the  suppuration  and  natural  course  of  the  disease.  Moderate 
purgation  for  a  few  days  with  Rochelle  salt  or  mineral  water  will  often  check  the  tendency 
to  a  fresh  crop  of  boils. 

As  for  local  treatment  a  poultice  is  of  the  greatest  service  in  the  incipient  stage,  when 
pain  and  tension  of  the  sldn  are  present.  As  soon  as  the  boil  "points"  it  should  be  freely 
lanced,  or  carbolic  acid  introduced  into  the  sloughing  centre.  The  latter  plan  of  treatment 
J3  usually  more  agreeable  to  the  patient.  My  plan  has  commonly  been  to  prick  the  boil  at 
";his  stage  with  a  sharp  splinter  or  wooden  toothpick  dipped  in  carbolic  acid.  As  soon  as 
the  opening  is  sufficiently  large,  a  little  cotton  wound  around  the  point  of  the  toothpick  and 
immersed  in  the  acid  should  be  introduced  into  all  parts  of  the  furunculous  cavity.  This 
procedure  soon  lessens  the  pain  and  swelling,  and  promotes  a  radical  cure. 

CARBUNOULUS. 

Synonyms — Anthrax —  Carbuncle. 

A  carbuncle  is  of  the  nature  of  the  furuncle,  but  is  distinguished  from  it  by  the  greater 
extent  of  tissxie  involved,  the  severity  of  the  constitutional  symptoms  which  precede  and 
accompany  the  local  inflammation,  and  by  the  gravity  of  its  prognosis.  It  begins  with  pain 
and  induration  of  a  small  portion  of  skin,  and  quickly  forms  a  flattened  tumor  of  the  size  of 
an  egg.  The  skin  is  at  first  merely  reddened,  but  gradually  assumes  a  dull,  livid  hue.  In  a 
few  days  a  number  of  openings  appear  upon  the  surface,  from  which  mingled  blood  and  pus 
can  be  readily  pressed.  A  number  of  separate  sloughs  may  form  at  these  points,  or  the 
whole  tumor  may  become  necrotic  in  character  and  form  a  greyish  or  blackish  mass.  This 
is  gradually  cast  off,  and  leaves  usually  a  very  deep  ulcer,  which,  under  favorable  circum- 
stances, heals  slowly  and  produces  a  hard  and  puckered  cicatrix.  At  the  outset  the  pain  is 
excessive,  and  lasts  until  sloughing  has  taken  place.  A  chill  often  precedes  the  develop- 
ment of  the  inflammation,  and  a  high  degree  of  fever  accompanies  its  progress.  Inflamma- 
tion of  pleura  or  lung  sometimes  occurs  and  symptoms  of  pyaemia  are  always  liable  to 
appear  and  lead  to  a  fatal  result.  In  many  cases  of  carbuncle  in  those  advanced  in  life, 
death  results  from  exhaustion.  The  seat  of  the  affection  is  usually  the  neck  or  back,  but  it 
may  attack  the  anterior  portion  of  the  chest,  or  other  portions  of  the  body. 

TREATMENT.  The  Strength  of  a  patient  attacked  by  carbuncle  must  be  maintained  by 
beef  tea  and  stimulants.  Quinine,  given  in  full  doses,  is  generally  of  service.  As  in  fur- 
uncle, calx  sulphurata  will  tend  to  check  the  inflammation  at  the  beginning,  and  hasten  the 
suppuration  at  a  later  stage.- 

The  most  approved  local  treatment  is  a  deep  crucial  incision  as  soon  as  suppuration  is 
established.  The  pain  of  this  operation  can  be  lessened  by  previously  freezing  the  skin  with 
an  ether  spray  or  an  application  of  salt  and  ice.  Carbolic  acid  may  be  injected  subcuta- 
neous] y  at  the  very  outset,  and  should  be  freely  and  repeatedly  applied  in  an  undiluted  form 
us  soon  as  the  incision  has  been  made.

DJSEA&ES  OF  THE  SKIN.— INFLAMMATORY. 


ULCUS. 

Synonym —  ZTleer, 

An  ulcer  ia  a  lesion  of  the  skin  or  mucous  membrane,  characterized  by  loss  of  tissue  and 
slight  disposition  to  spontaneous  heaUng.  In  the  latter  respect  it  differs  from  au  ordinary 
wound. 

Some  dermatological  writers  do  not  regard  an  ulcer  as  a  distinct  disease  of  the  skin,  but 
consider  it  as  a  mere  lesion  occurring  in  the  course  of  various  diseases.  Other  writers  treat 
of  cutaneous  ulcers  as  a  distinct  class  of  skin  diseases.  Certaialy  the  importance  of  these 
lesions,  whatever  may  be  their  cause,  is  an  ample  warrant  for  a  separate  consideration  of 
their  peculiar  features. 

Ulcers  in  general  vary  greatly  in  size  and  shape,  in  the  character  of  theii"  surface  and 
border  and  in  the  condition  of  the  surrounding  skin.  Small  ulcers,  occurring  where  the  skin 
is  rather  tightly  drawn,  are  commonly  circular,  while  larger  ones  may  be  oval,  elliptical, 
kidney-shaped,  or  irregular  m  outline. 

The  surface  of  an  ulcer  is  sometimes  smooth  and  clean,  of  a  bright  red  color,  and  char- 
acterized by  the  small  hemispherical  granulations  which  give  promise  of  a  speedy  cicatrization. 
On  the  other  hand  it  may  be  covered  with  a  foul  secretion,  which  adheres  to  and  conceals  its 
base,  or  the  granulations  may  be  of  an  exuberant  fungous  character,  rising  above  the  surface 
of  the  skin  at  the  margin  and  giving  rise  to  the  common  term,  "proud  flesh."  Frequently 
these  granulations  are  extremely  painful  upon  the  slightest  pressure  and  bleed  at  the  slight- 
est touch.  Occasionally  the  surface  presents  a  diphtheritic  appearance,  being  covered  by  a 
yeUowish-wliite  tenaceous  membrane.  A  crust  of  a  yellowish,  greenish  or  blackish  hue  and 
variable  thickness  often  forms  upon  and  adheres  to  the  edges  of  the  ulcer. 

The  border  of  an  ulcer  may  be  smooth  and  soft,  or  on  the  other  hand  elevated  consider- 
ably above  the  level  of  the  skin  and  more  or  less  indurated.  The  wall  of  this  border  may 
slope  gradually  to  the  edge  of  the  granulations,  may  be  abrupt  or  steep,  and  finally  the  bor- 
der may  be  undermined  to  a  considerable  extent. 

Thf  skin  surrounding  an  ulcer  may  be  in  a  perfectly  normal  condition,  or  considerably 
inflamed  and  swollen.  Upon  the  legs  it  is  often  eczematous  in  character  and  usually  pig- 
mented and  scaly. 

Ulcers  occur  as  a  result  of  the  softening  of  various  neoplastic  growths  or  as  the  result  of 
an  inflammatory  process.  In  the  former  class  we  have  those  which  are  common  in  lupus 
leprosy,  cancer  and  the  gummy  deposits  of  syphilis.  In  the  latter  class  we  have  both  idio- 
pathic ulcers  and  such  as  are  caused  by  scurvy,  scrofula  and  syphilis  in  its  early  stages. 

Treatment.  In  the  treatment  of  ulcers  two  main  objects  are  to  be  considered,  the 
removal  of  the  cause  so  far  as  this  is  possible,  and  the  adoption  of  such  measures  as  will  tend 
to  convert  the  ulcer  into  a  healthy  granulating  wound.  The  disease  of  which  the  ulcer  is 
merely  an  incidental  feature  must  be  treated  upon  principles  elsewhere  laid  down.     The 

(110) 


ULCUS. 

intlauiiuatory  condition  whicli  predisposes  to  its  development  must  be  combatted  witli  auii- 
pMogistic  measures,  while  the  new  growth,  which  is  so  often  its  cause,  must  be  destroyed. 
The  mechanical  agencies  which  aggravate  even  when  they  do  not  cause  the  ulcer  must  be 
counteracted  by  the  exercise  of  the  utmost  care  and  attention 

Since  of  all  ulcers,  those  occurring  upon  the  leg  are  most  common  and  most  frequently 
rebellious,  the  limited  space  at  command  may  be  best  devoted  to  their  treatment.  A  routine 
plan  will  not  suffice  here.  While  one  leg  ulcer  needs  the  most  tender  care  another  will  only 
respond  to  harsh  methods.  The  first  and  a  most  important  step  is  to  decide  as  to  the  nature 
or  cause  of  the  ulcer,  and  for  practical  purposes  leg  ulcers  may  be  conveniently  divided  into 
three  classes,  viz.  :  syphilitic,  eczematous  and  simple  ulcers.  If  the  ulcer  is  situated  upon 
the  upper  third  of  the  leg  and  not  transmatic,  it  generally  owns  a  syphilitic  origin  and  de- 
mands specific  remedies.  The  same  rule  holds  as  to  leg  ulcers,  which  are  kidney-shaped  or 
midtiple,  and  arranged  in  a  semi-circle,  or  occurring  upon  a  swollen  ankle  with  deep  siausea 
apparently  reaching  to  the  bone.  If  an  ulcer  is  surrounded  by  a  broad  zone  of  reddened  or 
pigmented  skin  it  is  usually  the  result  of  a  pre-existing  or  present  eczema.  The  leg  is  usu- 
ally larger  than  its  mate  and  swells  considerably  after  the  patient  has  walked  or  stood  for 
some  time.  The  ulcer  is  apt  to  be  painful  and  frequently  is  associated  with  a  varicose  condi- 
tion of  the  veins.  In  such  a  case  it  is  always  advisable  to  put  the  patient  to  bed  or  to  keep 
the  leg  constantly  elevated,  if  either  course  is  possible.  This  being  rarely  the  case  in  prac- 
tice among  the  poorer  classes  the  next  best  thing  tp  do  is  to  bandage  the  leg  carefully  and 
teach  the  patient  to  do  the  same  every  morning  before  getting  out  of  bed.  A  light  cheese- 
cloth roller  bandage  is  the  best  adapted  to  this  class  of  cases,  as  a  rubber  bandage  is  liable  to 
cause  the  eczema  of  a  congested  leg  to  spread.  If  the  ulcer  is  foul  a  little  charcoal  or  iodo- 
form may  be  applied  to  the  surface  and  covered  with  a  thick,  soft  muslin.  If  it  is  painful 
and  presents  a  thin  ichorous  discharge  there  is  no  better  application  than  the  subnitrate  of 
bismuth  beneath  the  bandage.  It  may  be  advisable  to  apply  an  ointment  to  the  eczematous 
skin  around  the  ulcer  but  not  as  a  rule  to  the  ulcer  itself. 

A  simple  ulcer,  resulting  originally  in  traumatism,  may  be  irritable  or  indolent.  In  the 
former  case  it  needs  rest  and  the  constant  application  of  hot  fomentations.  Indeed,  if  a  patient 
can  be  kept  in  bed,  no  matter  whether  an  ulcer  is  a  simple  or  a  syphilitic  one,  healthy  or 
sloughing,  there  is  no  local  treatment  which,  in  my  experience,  will  compare  with  the  fre- 
quent application  of  hot  cloths.  If  the  ulcer  is  indolent  with  a  glazed  surface  and  caUous 
edges  an  excellent  plan  is  to  place  the  leg  in  hot  water  every  day  and  puncture  the  iilcer  and 
surrounding  skin  with  the  point  of  a  lancet  until  the  blood  flows  freely  from  a  score  or  more 
of  small  incised  wounds.  When  a  large  ulcer  has  been  brought  to  a  healthy  granulating 
condition  the  healing  process  can  be  greatly  hastened  by  the  adoption  of  the  process  known 
as  skin  grafting.

DISEASES  OF  THE  SKIN—INFLAMMATORY. 


ONYCHIA. 

Synonym — Paronychia. 

OnycMa  is  a  term  applied  to  inflammation  of  the  soft  tissue  beneath  or  around  the  nail. 
In  most  cases  the  fold  of  skin  rising  above  the  lateral  border  of  the  naU  is  the  part  affected 
(onychia  lateralis),  but  sometimes  the  inflammation  takes  place  at  the  root  of  the  nail  or  in 
the  underlj'ing  tissue. 

Onychia  lateralis  or  Paronychia  most  frequently  affects  the  great  toe,  and  constitutes  a 
painful  and  annoying  affection.  By  the  almost  constant  pressure  of  tight  shoes  the  external 
border  of  the  nail  becomes  unduly  curved,  and  the  swelling  of  the  soft  parts  in  the  immedi- 
ate vicinity  produce  that  chronic  condition  which  is  commonly  known  as  "  in-growing  toe 
naU."  Frequently  the  inflamed  skin  at  the  side  of  the  nail  ulcerates,  as  the  result  of  pres- 
sure and  fimgous  granulations  spring  up  over  the  surface.  Paronychia  of  the  finger  nails  is 
usually  the  result  of  injury,  and  runs  an  acute  course.  Suppuration  usually  takes  place  in  a 
few  days  along  the  border  of  the  nail  after  which  the  pain  and  swelling  subsides,  although 
the  inflammation  may  extend  to  the  matrix  of  the  nail  and  cause  the  latter  to  be  cast  off. 

Inflammation  of  the  root  of  the  nail  (onychia  retrounguealis)  and  the  underlying  soft 
\)ViYt  (onychia  subunguealis)  may  occur  as  the  result  of  injury  or  in  connection  with  syi^hilis) 
variola  or  scrofula.  This  form  of  onychia  is  usually  more  severe  and  commonly  results  in 
the  loss  of  a  portion  or  the  whole  of  the  nail.  With  the  subsidence  of  the  acute  inflamma- 
tion the  new  naU  begins  to  form  and  in  time  rises  and  loosens  the  old  one. 

The  diagnosis  of  onychia  from  affections  of  the  nail  substance,  to  be  mentioned  later, 
depends  upon  the  presence  of  inflammation. 

TiiEATMENT.  The  Occurrence  of  inflammation  about  the  nail  occurring  after  injury  may 
be  avoided  to  a  certain  extent  by  the  immediate  immersion  of  the  part  in  hot  water.  When 
a  spontaneous  paronychia  is  threatening,  the  progress  of  the  inflammation  can  often  be 
checked  by  painting  the  reddened  and  slightly-swoUen  skin  with  a  ten  per  cent,  solution  of 
nitrate  of  silver.  When  the  inflammation  is  well  established  and  especially  when  there  is 
ulceration  present  the  best  method  of  treatment  is  the  constant  application  of  the  following 
ointment. 

^     Iodoform,  10  parts. 

Balsam  of  Peru, 20     " 

Petrolatum  to  ....        loo      " 

M. 

This  may  prove  too  stimulating  in  certain  cases,  and  therefore  be  adapted  only  to  the 
healing  stage  of  the  affection,  bat  in  many  chronic  and  indolent  cases  it  will  produce  most 
beneficial  results. 

In  all  cases  of  onychia  not  of  traumatic  origin  the  possibility  of  its  deijendence  upon 
f;y]ilini=!  nr   scrofula  must  be  carefully  considered  and  the  appropriate  general  treatment 

a(ln|.I.ll. 

(112) 


ONTCAIA. 

The  management  of  in-growing  toe-nails  and  the  frequently  resulting  inflammation  often 
requires  the  most  careful  attention  and  skill.  The  ordinary  discomfort  which  so  many  expe- 
rience from  a  slight  degree  of  incurvation,  if  it  be  neglected,  can  best  be  relieved  by  paring 
the  comer  of  the  naU  as  far  back  as  possible  after  it  has  been  thoroughly  softened  by  a  pro- 
longed hot  foot  bath.  When  painful  inflammation  is  present  a  broad  shoe  or  slipper  must 
be  worn  until  it  subsides.  When  ulceration  has  taken  place  the  granulating  surface  must  be 
carefully  separated  from  the  naU.  This  can  be  accomplished  in  the  following  manner  :  The 
nail  should  first  be  scraped  to  render  it  as  thin  and  flexible  as  possible.  A  hot  foot  bath  will 
then  soften  the  skin  and  render  it  less  painful.  The  edge  of  the  nail  can  now  be  carefully 
raised  and  a  thin  piece  of  lead  or  even  a  strip  of  linen  pressed  beneath  it.  Into  the  sulcus 
beside  the  naU  a  little  charpie  must  be  pressed  and  the  soft  parts  drawn  away  from  the  bor- 
der of  the  nail  as  far  as  possible  by  the  traction  of  narrow  strips  of  adhesive  plaster  carried 
under  the  toe.  This  plan  of  treatment  insures  speedy  relief  and  usually  effects  a  cure  of  the 
trouble  in  the  course  of  a  month. 

Avulsion  of  the  naU  or  excision  of  the  lateral  portion  has  been  highly  recommended 
by  many  surgeons,  and  it  is  claimed  that  the  very  best  result  can  be  most  speedily  attained 
by  simply  cutting  away  the  soft  tissue  which  crowds  against  and  over  the  curved  edge  of 
the  nail.

CHAPTER  m. 

HEMORRHAGIC  AFFECTIONS. 

An  effasion  of  blood  from  the  cutaneous  capillaries  may  result  from  three  causes,  viz., 
external  riolence,  increased  blood-pressure,  and  weakness  of  the  vascular  walls.  In  many 
cases  of  cutaneous  hemorrhage  a  rupture  of  the  vessels  takes  place,  but  on  the  other  hand  it 
is  possible  for  the  blood  corpuscles  to  pass  through  the  uninjured  waUs  of  the  capillaries,  and 
without  doubt  this  process  (diapedesis)  fi-equently  occurs.  To  all  forms  of  cutaneous  hem- 
orrhage some  writers  have  applied  the  term  purpura,  which  is  manifestly  wrong,  since  it 
places  a  flea-bite  or  a  "black-eye"  in  the  same  category  with  scurvy.  The  term  purpura 
should  be  used  in  a  restricted  sense,  and  applied  only  to  an  independent  disease,  in  which 
cutaneous  hemorrhages  occur  as  a  primary  lesion.  This  excludes  the  hemorrhage  resulting 
from  a  blow,  fall,  or  the  bite  of  an  insect,  as  also  that  which  is  due  to  obstruction  of  the 
venous  circulation.  It  excludes  the  hemorrhage  which  occurs  secondarily  in  the  course  of 
the  exanthematous  fevers  (e.  /7.,  Variola  hemorrhagica),  and  in  certain  inflammatory  skin 
affections,  such  as  erythema,  urticaria  and  pemphigus.  Finally,  it  excludes  scorbutus  (or 
scurvy),  as  being  an  affection  due  to  a  defiaite  and  well-known  cause. 

Cutaneous  hemorrhage  may  occur  in  the  form  of  numerous  punctate  spots  I'esembliiig 
Tleabites  (petechise),  as  fine  lines  or  streaks  (vibices),  or  as  discolored  patches  of  various  size 
and  shape  (ecchymoses).  In  rare  instances  the  effused  blood  raises  the  epidemiis  and  forms 
what  is  sometimes  termed  a  '"blood-blister"  (ecchyraoraa).  Cutaneous  hemofrliages  are 
classed  as  traumatic  and  spontaneous. 

PURPURA, 

It  is  customary  to  describe  three  forms  of  purpura.  In  the  most  common  form,  or  pur- 
pura simplex,  numerous  small  spots,  of  a  bright  purplish-red  or  claret  color,  appear  suddenly 
on  the  lower  extremities,  and  in  rare  instances  on  other  portions  of  the  body.  They  occur 
spontaneously,  and  are  usually  unaccompanied  by  any  marked  general  symptoms.  The 
bright  color  changes  in  the  course  of  a  few  days  to  a  dull  red,  and  after  assuming  the  green- 
ish and  yellowish  hues  so  frequently  noted  after  an  ordinary  bruise,  the  spots  gradually 
disappear.  Fresh  extravasations  often  appear  from  time  to  time  during  the  course  of  the 
affection,  and  thus  a  contrast  of  colors  may  result.  The  spots  commonly  vary  in  size  from 
a  pinhead  to  a  small  pea,  are  not  at  all  elevated,  and  do  not  disappear  on  pressure.  Some- 
times they  are  slightly  prominent  at  the  outset,  and  sometimes  large  Livid  patches  develop.

PURPURA. 

^Vht'D  ihe  liemorrhage  takes  place  in  or  around  the  hair  follicles  a  papular  form  of  purpura 
is  developed  \v^hich  was  formerly  described  as  lichen  lividus,  and  later  by  Hebra  as  purpura 
papulosa. 

Purpura  hemorrhagica  is  a  more  aggravated  form  of  the  disease,  in  which  large  cutane- 
ous extravasations  are  seen,  not  only  on  the  skin,  but  also  upon  the  mucous  membranes. 
Hemorrhages  from  the  nose  and  gums  occur,  as  also  bloody  stools  and  urine  The  constitu- 
tional symptoms  are  marked,  and  the  weakness  resultuig  from  a  continued  loss  of  blood  may 
lead  to  a  fatal  termination. 

Purpura  (or  peliosis)  rheumatica  is  a  peculiar  affection  (conveniently  regarded  at  present 
as  a  form  of  purp^dra),  in  which  arthritic  pains  and  fever  precede  an  eruption  of  small 
hemorrhagic  macules  upon  both  trunk  and  extremities.  The  disease  usually  runs  a  brief 
course,  although  a  repeated  onset  of  fever  and  rheumatic  pains,  followed  by  cutaneous 
hemorrhages,  may  protract  it  for  months.  It  commonly  attacks  those  who  have  a  rheumatic 
tendency,  but  are  otherwise  apparently  well. 

Diagnosis.  The  diagnosis  of  the  simple  and  hemorrhagic  forms  of  purpura  is  unat- 
tended with  difficulty.  To  the  practiced  eye  the  cutaneous  lesions  are  characteristic,  but 
their  hemorrhagic  nature  can  be  easily  verified  by  noting  the  fact  that  they  do  not  change  in 
color  under  the  pressure  of  the  finger,  a  circumstance  which  enables  the  tyro  to  distinguish 
them  from  inflammatory  lesions.  Scorbutus,  or  sea-scurvy,  is  regarded  as  distinct  from 
purpura  hemorrhagica,  on  account  of  its  gradual  development,  the  mai-ked  swelling  of  the 
gums,  with  loosening  of  the  teeth,  and  the  extreme  debility,  which  are  its  prominent  fea- 
tures ;  and  from  the  fact  that  it  occurs  so  frequently  among  sailors  and  those  who  cannot  or 
do  not  eat  fresh  vegetables.  Purpura  rheumatica  may  be  readily  mistaken  for  rheumatism 
during  the  few  days  which  precede  the  outbreak  of  the  characteristic  eruption.  Tilbury 
Pox  regarded  this  form  as  simply  an  erythema,  complicated  by  hemorrhage. 

Treatment.  The  treatment  of  purpura  consists  chiefly  in  removing  any  cause  which  may 
be  ascertainable,  and  in  enjoining  absolute  rest  where  the  hemorrhages  are  severe  and  frequent. 
Iron,  ergot,  the  mineral  acids  and  quinine  are  remedies  of  value,  although  too  much  reliance 
may  be  placed  upon  their  action,  and  too  little  thought  given  to  the  question  of  rest,  proper 
diet,  and  the  hygienic  influences  which  surround  the  patient.  In  mUd  cases  of  iDurpura  sim- 
plex a  moderate  amount  of  exercise  is  rather  advantageous  than  otherwise,  and  often  the  treat- 
ment need  not  interfere  with  the  daily  duties  of  the  patient.  No  remedy  can  be  given  to 
hasten  the  disappearance  of  the  hemorrhagic  spots,  but  fuU  doses  of  the  tincture  of  the  chlo- 
ride of  iron  will  usually  check  the  development  of  new  lesions,  and  improve  the  general  con- 
dition of  the  patient.  In  purpura  rheumatica  the  patient  usually  recovers  speedily  under 
good  nursing,  although  an  anodyne  may  be  necessary  to  relieve  pain,  and  a  tonic  of  iron  or 
quinine  prove  serviceable  at  the  close  of  the  attack.  In  purpura  hemorrhagica  the  patient 
must  be  kept  as  quiet  as  possible.  Ergot  may  be  given  by  the  mouth  or  by  hypodermic 
injection.  For  the  latter  purpose  dissolve  six  centigrams  (one  grain)  of  ergotin  in  warm 
water  and  glycerine.     This,  with  the  use  of  ice,  will  promptly  control  the  hemorrhage  from

ttie  mucous  membranes.  A  diet  of  fresli  vegetables,  which  invariably  produces  such  a  bene- 
ficial change  in  scorbutus  (sea  scurvy)  is  of  no  value  in  the  treatment  of  purpura  hemorrha- 
gica. 

SCORBUTUS. 

Syii  onym — Scurvy. 

Under  certain  conditions,  prominent  among  which  is  an  insufficiency  of  proper  food,  a 
train  of  symptoms  occur  to  which  the  term  scurvy  is  commonly  applied.  The  affection  is 
characterized  by  general  malnutrition,  extreme  prostration,  difficult  breathing,  a  swollen  and 
spongy  condition  of  the  gums  and  the  occurrence  of  purpuric  spots  upon  the  skin.  It  com- 
monly makes  its  appearance  among  sailors  on  long  sea  voyages,  and  in  armies  whose  base  of 
supplies  has  been  cut  off.  It  also  occurs  in  isolated  cases  among  the  poverty-stricken  popu- 
lation of  many  of  our  large  cities.  In  this  case  it  is  sometimes  spoken  of  as  "  land-scurvy," 
although  its  nature  is  identical  with  the  affection  so  commonly  associated  with  the  sea. 

The  cause  of  scurvy  has  been  the  subject  of  considerable  discussion.  Some  have  attrili- 
uted  it  to  the  eating  of  too  much  salt  meat,  of  foods  deficient  in  the  salt  of  potash  or  in 
phosphoric  acid,  etc.,  but  it  is  now  generally  believed  that  a  deficiency  of  the  organic  acids 
in  the  food  is  the  chief  cause  of  the  disease.  It  is  certain  that  scurvy  never  develops  among 
any  class  of  men  who  are  plentifully  supplied  with  fresh  vegetables. 

Treatment.  The  means  required  for  the  prevention  of  scurvy  are  evident  from  what 
has  been  said  of  its  cause.  The  same  treatment  will  also  cure  the  disease  when  once  estab- 
lished. But  on  shipboard,  or  in  a  besieged  city,  fresh  vegetables  are  a  remedy  not  always 
attainable,  and  lemon  juice  has  been  found  to  constitute  the  best  substitute.  Dried  vegeta- 
bles, vinegar  and  citric  acid  are  likewise  of  great  value.

CHAPTER  IV. 

HYPERTROPHIC  DISEASES. 

The  clasa  of  hypertrophic  affections  embraces  those  which  are  characterized  by  an  in- 
creased volume  of  one  or  more  of  the  normal  elements  of  the  skin.  In  clinical  appearance 
and  pathological  importance  they  differ  widely  among  each  other.  They  are  chronic  in  their 
course,  whether  congenital  or  acquired,  and  the  majority  are  but  slightly  amenable  to  treat- 
ment. 

Of  the  anomalies  of  pigmentation  which  form  a  division  of  this  class,  we  have  several 
affections  or  phases  of  cutaneous  disease  which  might,  with  propriety,  be  described  under 
one  title,  but  time-honored  custom  has  bestowed  upon  these  separate  forms  of  pigmentary 
disease  a  number  of  names  which  cannot  easUy  be  banished  from  dermatological  Literature, 
and  hence  it  is  convenient  to  describe  them  as  distinct  affections. 

N-EVUS  PIG-MENTOSITS. 

Synonym — Pigmentary  Mole. 

A  pigmentary  nsevus  is  a  discolored  spot  or  freckle  which  usually  appears  in  early  life, 
and  persists  without  undergoing  any  marked  change  in  size  or  color.  This  affection  is  often 
spoken  of  as  being  congenital  but  is  rarely  so.  The  simplest  form  of  nsevus  pigmentosus  is 
a  small  pin-head  sized  brownish  or  blackish  spot  of  so  trifling  a  character  that  a  number  of 
them  may  exist  upon  the  skin  of  a  person  whose  attention  has  never  been  directed  to  them, 
and  who  would  swear,  Lf  called  upon  to  do  so,  that  his  skin  was  absolutely  free  from  any 
blemish.  A  pigmentary  nsevus  is  round  or  elliptical  in  shape,  perfectly  smooth,  and  accom- 
panied by  Ao  subjective  sensation.  It  is,  in  short,  a  permanent  freckle  {Nosvus  spilus).  In 
some  cases  this  spot  may  be  as  large  as  the  print  of  the  thumb  and  similar  in  shape,  while 
in  rare  instances  large  portions  of  the  trunk  are  the  seat  of  a  cii-cumscribed  discoloration. 
In  certain  cases  the  nsevus  is  elevated  and  somewhat  Avarty  in  character  {Ifcevtts  verrucosus), 
and  very  often  is  covered  with  a  growth  of  hair  {Ncbvus  pilosus). 

Treatment.  A  small,  smooth  nsevus  may  be  removed  from  the  face  or  hands,  where  it 
is  most  apt  to  prove  annoying,  by  applying  carefully  a  drop  of  nitric  acid  or  whatever  wiU 
produce  the  faintest  possible  cicatrix.  The  warty  form  of  nsevus,  which  is  sometimes  pen- 
dulous, can  best  be  removed  by  knife  or  scissors.

DISEASES  OF  THE  SKIN— HYP ERTROPHIO. 


LENTIGO. 

Synonyms — Ephelis — Freckles. 

Freckles  are  small  circumscribed  yellowish  or  brownish  discolorations  of  the  skin,  result- 
ing from  an  abnormal  deposition  of  pigment.  They  are  usually  of  the  size  of  a  pin-head 
and  discrete,  but  in  some  cases  they  are  somewhat  larger  and  often  so  numerous  that  a  dark 
patch  of  considerable  size  is  formed  by  their  coalescence  Upon  the  face,  and  particularly 
upon  the  nose  and  cheeks,  they  are  most  frequently  observed,  but  they  are  not  uncommon 
upon  the  backs  of  the  hands  and  upon  the  neck  and  arms  after  habitual  exposure  of  these 
parts.  In  rare  instances  they  occur  upon  the  trunk,  thighs  and  other  covered  portions  of  the 
body.  I  have  a  photograph  of  one  case  in  which  they  were  abundant  upon  the  abdomen  and 
penis.  In  this  instance  they  were  persistent,  like  pigmentary  nsevi,  but  became  much  darker 
and  more  striking  in  appearance  every  summer,  though  not  exposed  to  the  direct  action  of 
the  sunlight. 

While  the  tendency  of  certain  individuals  to  freckle  is  evident  to  the  simplest  obser\a- 
tion,  the  reason  of  this  fact  is  not  readily  discovered.  Persons  with  a  fair  complexion  and 
reddish  hair  are  far  more  likely  to  become  freclded  than  those  of  the  brunette  type,  and 
among  mulattoes  the  most  marked  cases  of  lentigo  are  to  be  found.  This  affection  is  rarely 
if  ever  seen  in  infancy,  but  is  common  in  early  life.  In  old  age  pigmentary  discolorations 
are  very  common,  especially  upon  the  face  and  hands,  but  the  freckles  which  come  in  sum- 
mer and  disappear  in  winter  are  not  observed  at  this  time  of  life. 

Treatment.  Since  freckles  do  not  affect  the  corium  or  true  skin,  but  result  from  an 
increased  amount  of  coloring  matter  in  the  deepest  layer  of  cells  of  the  epidennis,  it  is  evi- 
dent that  blistering  or  any  kind  of  treatment  which  will  remove  the  epidermis  will  remove 
the  frecklps.  But  the  effect  of  this  treatment  is  merely  temporary,  and  with  the  renewal  of 
the  epidermis  a  new  deposition  of  pigment  is  likely  to  take  place.  The  tendency  to  the  for- 
mation of  frecldes  in  certain  individuals  cannot  be  remedied,  but  by  avoiding  exposure  of 
the  skin  to  the  direct  rays  of  the  sun  in  warm  weather,  the  unsightly  spots  can  be  avoided 
to  a  certain  extent.  Of  the  various  tan  and  freckle  lotions  which  have  been  recommended 
highly  and  used  extensively  my  o^vn  experience  wiU  not  allow  me  to  speak  in  very  high 
praise.     One  of  the  following  may  prove  of  value  as  a  placebo  if  it  does  no  other  good.

According  to  Shoemaker  the  careful  application  of  a  small  piece  of  the  ointment  of  the 
oleate  of  copper  at  night  upon  retiring  will  usually  remove  freckles.  The  oleate  of  copper 
ointment  should  be  prepared  by  dissolving  the  salt  of  oleate  of  copper  in  sufficient  oleo- 
palmitic  acid  to  make  a  soft  ointment. 

CHLOASMA. 

Synonym — Liver  Spot. 

Chloasma  is  a  yellowish  or  brownish  discoloration  of  the  skin  which  commonly  shows 
itself  in  symmetrical  patches  upon  the  face.  Some  writers  include  under  the  name  chlo- 
asma a  variety  of  i>igmentary  affections  resulting  from  Avidely  different  causes,  distinguish- 
ing them  as  idiopathic  and  symptomatic.  The  term  has  even  been  applied  to  one  of  the 
parasitic  affections.  If  we  include  under  the  term  chloasma  both  the  pigmentation  of  the 
skin  resulting  from  the  application  of  a  mustard  plaster  or  from  persistent  scratching,  and 
that  which  is  caused  by  the  internal  use  of  nitrate  of  silver,  Addison's  disease  or  the  can- 
cerous cachexia,  there  is  no  reason  why  it  should  not  be  made  to  cover  lentigo  and  nsevus. 
It  were  better  if  the  term  chloasma  should  be  limited  ia  its  application  to  that  form  of  pig- 
mentary disease  which  is  commonly  spoken  of  as  chloasma  uterinum,  although  it  appears 
in  the  majority  of  cases  to  have  no  more  connection  with  the  uterus  than  it  has  with  the  liver. 

The  patches  of  chloasma,  limiting  the  signification  of  the  term  as  above  indicated,  are 
never  small  and  distinct,  rarely  rounded  or  elliptical  in  shape,  but  usually  irregular  in  form, 
and  with  an  ill-defined  border.  The  color  is  not  apt  to  be  very  pronounced,  although  in 
summer  the  affection  is  much  more  noticeable  than  iu  winter.  The  forehead  and  malar  region 
is  the  favorite  seat  of  chloasma,  and  there  may  be  a  number  of  isolated  patches  of  discolora- 
tion or  one  large  patch  covering  the  upper  portion  of  the  face  like  a  mask.  This  mask  never 
involves  the  whole  of  the  skin  of  this  region,  but  stops  abruptly  a  short  distance  from  the 
scalp  or  the  eyebrows,  and  thus  leaves  some  normal  skin  which  renders  the  patches  more 
unsightly  by  the  contrast  which  the  normal  skin  affords.  The  patches  of  chloasma  are  less 
common  upon  the  lower  half  of  the  face.  Occasionally  patches  are  to  be  found  upon  the 
neck  and  trunk. 

Females  are  commonly,  but  by  no  means  exclusively,  the  subjects  of  chloasma,  and 
although  it  manifests  a  marked  tendency  in  this  sex  to  make  its  appearance  dm-ing  preg- 
nancy, it  is  not  infrequently  met  with  among  chUdless  women  and  spinsters.  Occurring 
during  the  months  of  pregnancy  it  often  disappears  quickly  after  childbirth,  but  in  many 

(119) 


DISEASES  OF  THE  SKIN—RYPERTROPEIC. 

cases  it  persists  for  years,  thongh  in  a  somewhat  milder  degree.  It  is  never  observed  before 
puberty  and  rarely  continnes  after  tlie  menopause. 

Chloasma  results  from  an  abnormal  accumulation  of  pigment  in  the  epidermis,  and  the 
nerves  which  should  control  the  deposition  of  coloring  matter  evidently  fail  to  do  their  duty 
What  the  prime  cause  of  the  affection  may  be  is  difficult  in  most  cases  to  determine.  The 
dependence  of  the  discoloration  upon  uterine  disease  and  menstrual  irregularity  is  evident  in 
a  small  number  of  cases,  but  in  a  large  majority  it  appears  to  me  to  be  a  groundless  assump- 
tion. 

Diagnosis.  The  affection  with  which  chloasma  is  most  likely  to  be  confounded  is 
leucoderma,  the  lesions  of  which  are  very  apt  to  occur  upon  the  face  and  neck.  In  this 
affection  there  is  an  absence  of  pigment  in  circular  or  irregular  patches  with  sometimes  an 
increased  amount  of  pigment  in  the  vicinity.  In  chloasma  there  are  never  any  pale,  milk- 
white  spots  to  be  seen  and  the  skin  has  merely  a  darkened  or  dirty  appearance.  With  chro- 
mophytosis  a  mistake  ought  not  to  occur,  as  the  patches  in  this  affection  never  appear  upon 
the  face,  and  the  surface  of  the  affected  skin,  though  sometimes  apparently  smooth  like  that 
of  chloasma,  can  always  be  made  rough  or  mealy  by  simply  scratching  it  with  the  fingernail 
or  any  dull  Instrument. 

Argyiia,  the  bluish  or  slate  color  resulting  from  the  internal  use  of  nitrate  of  silver,  dif- 
fers from  chloasma  in  the  large  extent  of  surface  which  is  evenly  discolored,  and  in  the  fact 
that  the  hands  as  well  as  the  face  and  neck  are  usually  of  a  similar  hue. 

Treatment.  In  the  treatment  of  pigmentary  affections  no  brilliant  results  can  be  hoped 
for.  Indeed,  it  must  be  confessed  that  a  result  satisfactory  to  the  patient  is  not  frequently 
attained.  If  the  patient  be  pregnant  she  may  be  consoled  by  the  hope,  if  not  the  surety,  that 
a  little  patient  waiting  will  restore  her  former  complexion.  If  she  be  a  sufferer  from  dj's- 
menorrhoea,  treatment  of  this  condition  may  be  instituted  with  the  hope,  faint  as  it  is,  that 
normal  menstruation  wUl  be  accompanied  by  a  decrease  of  the  discoloration.  When  general 
treatment  or  special  treatment  for  the  removal  of  a  hypothetical  cause  has  failed  to  produce  a 
change  in  the  complexion,  the  local  measures  already  mentioned  in  connection  with  lentigo 
may  be  employed.  The  proxide  of  hydrogen  is  the  application  which,  in  my  hands,  has  pro- 
duced the  most  favorable  results.  Care  must  be  exercised  in  obtaining  a  sufficiently  strong 
preparation  and  in  keeping  the  bol  tie  well  corked  and  in  a  cool  place.  The  affected  skin 
may  be  painted  once  or  twice  daUy.  If  a  dark  camel' s  hair  pencil  be  used  the  first  effect 
of  the  peroxide  will  be  to  whiten  the  hairs  of  the  pencil.  If  this  does  not  occur  it  is  probable 
the  lotion  has  lost  its  strength  and  wiU  produce  little  or  no  effect  upon  the  skin. 

CALLOSITAS. 

A  callosity  is  a  hard  and  flattened  tumor,  but  slightly  elevated  above  the  surface  of  the 
skin.  It  is  the  result  of  an  increased  thickness  of  the  epidermis,  and  occurs  upon  such  por- 
tii.n*  of  the  body  as  are  subjected  to  friction  or  intermittent  pressure.     The  hands  and  feet 

(120) 


CLAVUS. 

are  the  parts  most  frequently  affected,  and  naturally  those  accustomed  to  manual  labor  or 
who  wear  coarse,  ill-fitting  shoes  are  most  likely  to  be  affected.  A  thick  and  horn-like 
epidermis  is  the  normal  covering  of  the  heel  and  ball  of  the  foot,  and  furnishes  the  natuiu] 
protection  which  is  usually  supplemented  by  artificial  plates  of  shoe-leather. 

In  walking  the  naturally  callous  portions  of  the  sole  should  be  a  help  rather  than  a 
hindrance,  but  when  as  a  result  of  high  heels,  short  or  Ul-fitting  shoes  or  congenital  talipes, 
the  foot  is  more  or  less  turned  or  twisted,  pressure  is  exerted  upon  a  patch  of  soft  epidermis 
which  gradually  thickens,  it  is  true,  but  often  becomes  inflamed  and  causes  no  little  amount 
of  inconvenience  and  suffering. 

CLAVUS. 

Synonym —  Corn. 

A  corn  is  a  callosity  of  pecrdiar  form  which  is  commonly  met  with  upon  the  toes.  Being 
the  result  of  pressure  it  naturally  forms  upon  the  skin  over  the  bony  enlargement  at  the  end 
of  the  first  phalanx,  and  most  frequently  upon  the  small  toe.  Corns  also  occur  over  the 
extremities  of  the  metatarsal  bones,  upon  the  soles  of  the  feet  and  in  rare  instances  upon  the 
hands.  Upon  the  dorsal  surface  of  the  toes  corns  are  dry  and  horny,  while  between  the  toes 
they  are  kept  constantly  macerated  and  appear  softer  and  white. 

A  hard  corn  is  slightly  elevated  above  the  surface  of  the  skin,  rounded,  flattened  and 
yellowish  in  hue.  The  under  surface  is  more  or  less  conical,  which  fact  has  given  rise  to 
the  common  idea  that  a  corn  has  I'oots. 

Treatment.  In  the  treatment  of  callous  patches  and  corns,  two  objects  should  be  kept 
in  view,  the  removal  of  the  cause  and  the  alleviation  of  the  suffering.  If  arrow  shoes  are, 
without  doubt,  the  most  frequent  cause  of  corns,  and  the  incalculable  amount  of  distress 
which  they  invariably  produce  in  all  civilized  communities  could  only  be  avoided  by  defying 
fashion  and  wearing  stout  moccasins,  or  shoes  shaped  like  the  feet.  Possibly  when  we  arrive 
at  the  highest  point  of  civilization  our  present  style  of  foot  covering  will  be  abandoned,  but 
under  the  present  condition  of  things  we  can  only  hope  to  secure  from  the  modern  shoema- 
ker a  somewhat  less  narrow  shoe  than  he  is  in  the  habit  of  making.  It  is  an  excellent  plan 
for  those  suffering  from  corns  and  bunions  to  have  a  number  of  pairs  on  hand  at  all  times  so 
that  a  frequent  change  can  be  made.  This  will  usually  obviate  the  continuous  pressure  upon 
a  given  point  and  the  resulting  inflammation.  To  soften  the  epidermis  various  applications 
may  be  advantageously  employed.  Prominent  among  these  are  glacial  acetic  acid  and  sali- 
cylic acid.  The  former,  if  applied  with  care  to  the  horny  epidermis  and  not  allowed  to  get 
upon  the  healthy  skin,  wUl  soften  a  painful  corn  or  callosity  so  that  the  bearer  can  once  more 
walk  with  comfort,  or  so  that  it  can  be  chiseled  out  of  its  bed  with  little  or  no  pain. 

Salicylic  acid  possesses  a  peculiar  faculty  for  softening  epidermic  tissue,  and  is  the  chief 
or  sole  ingredient  of  numerous  com  cures  now  in  the  market.  A  satui-ated  solution  in  alco- 
hol applied  repeatedly  will  soften  a  corn  so  that  it  can  be  readily  paired  away  or  dug  out 

(121) 


DISEASES  OF  THE  SKIN— HYPERTROPHIC. 

with  a  curette.  An  application  of  salicylic  acid  in  collodion  repeated  every  night  will  whiteii, 
soften  and  often  cause  the  disappearance  of  a  troublesome  com  or  callous  patch  in  a  few 
weeks. 

VERRUCA. 

Synonym —  Wart, 

An  ordinary  wart  (rerruca  vulgaris)  is  a  small,  dry  and  homy  tumor  most  commonly 
seen  upon  the  hands  of  children.  These  growths  are  multiple  and  vary  in  size  from  a  pin- 
head  to  a  pea.  Except  when  unusually  large  or  inflamed  they  occasion  little  or  no  discom- 
fort. They  usually  develop  quickly,  and  having  attained  their  full  size,  persist  for  an  indefi- 
nite time.  They  likewise  disappear  suddenly  in  some  cases  and  are  entirely  gone  before  the 
fact  of  their  going  is  perceived. 

The  hands,  and  especially  the  fingers,  are  their  favorite  location,  but  they  may  also 
occur  upon  the  scalp,  face  and  other  parts.  The  common  wart  may  present  a  somewhat 
smooth,  hard  and  flattened  surface,  or  it  may  be  considerably  elevated  above  the  level  of  the 
skin,  and  present  a  well-marked  digitate  surface. 

The  so-called  venereal  warts  are  soft,  moist  papillary  tumors,  commonly  met  with  upon 
the  genitals  of  both  sexes.  They  are  apt  to  be  much  larger  than  common  warts  and  some- 
times grow  to  large  fungous  masses  resembling  a  cock's  comb  in  appearance.  Thej"  are 
usually  of  a  bright  red  hue,  sometimes  dusky  or  bluish,  and  when  exposed  to  the  air  the 
surface  becomes  dry  and  blackened.  In  the  male  they  are  commonly  found  upon  the  mucous 
surface  of  the  prepuce,  and  upon  the  glans  penis.  In  this  location  they  often  occasion  a 
phimosis,  and  their  rapid  increase  in  size  soon  distends  the  prepuce  until  it  resembles  a  large 
ball.  When,  in  such  a  case,  the  prepuce  is  slit  up  and  retracted  it  is  not  uncommon  to  find 
that  a  portion  of  the  warty  mass  has  sloughed  from  its  base  and  is  ready  to  fall  out  when  no 
longer  confined  by  the  foreskin.  The  remaining  masses,  crowded  and  flattened  by  pressiu'e, 
give  the  glans  penis  the  appearance  of  a  small  red  cauliflower.  In  the  female  these  growths 
are  usually  seen  upon  the  fourchette  and  mucous  surface  of  the  labia.  Around  the  anus  in 
both  sexes  these  warts  are  often  seen  among  a  certain  class  of  patients  and  frequently  mista- 
ken for  an  evidence  of  syphilis.  The  moist  syphilitic  papules  which  are  common  in  this 
locality  in  an  early  stage  of  the  disease  sometimes  present  a  vegetating  or  fungous  surface, 
but  are  usually  flattened,  and  hence  called  condylomata  lata  in  distinction  from  the  non- 
syphilitic  warts  which  are  often  spoken  of  as  condylomata  acuminata.  Similar  growths 
may  be  met  with  in  the  umbilical  cavity  and  even  in  the  axillae,  between  the  toes  and  wher- 
ever the  predisposing  conditions  of  moisture  and  uncleanliness  co-exist.  They  always 
develop  rapidly  and  under  these  conditions  are  not  likely  to  disappear  spontaneously  like 
the  common  warts. 

The  cause  of  warts  is  obscure,  and  a  peculiar  disposition  to  both  varieties  is  observed  in 
many  individuals.     There  is  no  doubt  respecting  the  contagious  nature  of  acuminate  warts, 

(122) 


VERRUCA. 

and  it  is  quite  probable  that  many  cMldren  contract  ordinary  warts  from  the  hands  of  pi  y 
mates  who  are  affected. 

Diagnosis.  A  typical  wart  is  always  easily  recognized,  but  there  are  certain  affectio  t 
of  the  skin  of  a  warty  or  papillomatous  nature  which  the  most  experienced  dermatologi^  s 
often  find  difficult  to  name  and  classify.  These  are  rare,  however,  and  can  be  conveniently 
termed  Papilloma. 

Treatment.  In  the  treatment  of  ordinary  warts  a  great  variety  of  remedies  have  been 
recommended,  from  the  mildest  charm  to  the  severest  caustic,  and  perhaps  none  of  them  are 
absolutely  valueless.  Of  the  so-called  charms  employed  by  the  ignorant,  such  as  dipping  the 
hand  in  the  rain  water  which  has  collected  in  a  hollow  stump,  spitting  on  the  warts  successively 
with  an  appropriate  incantation,  etc.,  etc.,  a  great  deal  that  is  interesting  might  be  written. 
But  the  one  point  of  practical  importance  to  be  noted  is  that  some  of  these  charms  do  ap  pear 
in  certain  cases  to  work  wonders.  Leaving  out  the  untruthful  and  exaggerated  reports  of 
their  virtues  and  overlooking  the  numerous  cases  in  which  they  utterly  fail,  there  stUl 
remain  instances  in  the  experience  of  many  persons  where  a  large  crop  of  persistent  warts 
has  disappeared  suddenly  after  recourse  to  one  of  these  vulgar  methods  of  treatment.  I 
have  never  witnessed  anything  of  the  kind  myself,  but  will  admit  that  these  supposed  cures 
may  not  be  mere  coincidences,  but  the  indirect/  I'esult  of  the  charm,  the  attention  so  firmly 
directed  to  a  portion  of  the  body  having  induced  a  change  in  the  nutritive  process  taking 
place  there. 

Caustics  will  remove  a  wart  if  repeatedly  applied,  the  dead  portion  being  carefully  pared 
away  before  each  application.  Acid  nitrate  of  mercury,  nitric  acid,  chromic  acid  and  caus- 
tic' potassa  have  each  been  recommended  and  successfully  used,  but  glacial  acetic  acid  or  a 
saturated  solution  of  salicylic  acid  is  preferable  if  the  application  is  to  be  made  by  the 
patient.  It  is  claimed  that  crystals  of  chloride  of  ammonium  rubbed  upon  warts  upon  the 
hands  will  cause  their  gradual  disapearance.  All  I  can  say  of  this  remedy  is  that  I  have 
known  it  to  fail. 

Thuja  occidentalis  is  a  remedy  of  considerable  repute  in  the  treatment  of  both  ordinary 
and  venereal  warts.  Given  internally,  I  have  waited  in  vain  for  any  effect,  but  in  the  f oi-m  of 
a  tincture  applied  once  or  twice  daily,  I  have  seen  a  beneficial  action  in  a  number  of  cases. 
It  gradually  lessens  the  congestion  in  the  case  of  accuminate  warts,  causes  the  epidermis  to 
become  dry  and  friable  and  in  time  removes  the  growth  in  great  part  if  not  entirely.  The 
tincture  or  fluid  extract  used  should  be  made  from  the  fresh  leaves  of  the  plant  and  may  be 
applied  pure  or  diluted  with  water. 

The  quickest  way  to  remove  warts,  and  in  most  cases  the  best,  is  to  scrape  them  off  with 
a  rather  sharp  curette.  The  procedure  is  attended  with  a  little  pain,  but  even  a  child  can  be 
induced  to  have  a  number  removed  in  this  way  at  one  sitting.  The  base  of  the  wart  should 
be  first  scratched  or  cut  with  the  edge  of  the  curette,  when  one  or  two  vigorous  sweeps  of 
the  instrument  will  quickly  remove  the  growth  and  leave  a  circular,  punched-out  wound. 
The  bleeding  which  follows  is  usually  slight,  and   can  easily  be  checked  with  a  bit  of 

(123) 


DISEASES  OF  TUE  SKIN.—RYPERTEOPEIC 

styptic  cotton  or  a  drop  of  carbolic  acid,  which  will  also  tend  to  remove  any  possibility  of  its 
return. 

The  ligation  of  large  warty  masses  may  sometimes  be  advisable,  but  unless  the  base 
whicli  remains  is  thoroughly  cauterized  or  scraped,  they  will  speedily  grow  again.  The  cut- 
ting of  a  wart  is  always  a  foolish  precedure,  as  it  only  makes  it  bleed  freely  and  cannot  pos- 
sibly destroy  it.  Large  seed  warts  upon  the  fingers  may  be  quickly  and  thoroughly  removed 
by  grasping  them  between  the  blades  of  a  stout  pair  of  dressing  forceps  and  twisting  them 
suddenly  out  of  their  bed.  This,  however,  occasions  more  hemorrhage  than  the  use  of  the 
curette. 


MOLLUSCUM. 

Synonyms — M.  Contagiosum — M.  Epitheliale — Acne  Molhmcum. 

The  term  moUuscum  has  long  been  applied  to  two  distinct  affections,  viz.,  one  about  to 
be  described  {MoUuscum  contagiosum  of  Bateman),  and  one  which  will  be  described  later  in 
thLs  work  {Fibroma,  or  the  Molloscum  flbrosum  of  certain  writers).  The  affection  to  which 
the  term  molluscum  should  be  limited  consists  of  little  soft  tumors,  varying  in  size  from  a 
pin' s  head  to  a  small  pea,  mth  a  constricted  base,  a  central  depressed  orifice  and  whitish, 
cui'd}'  contents.  They  are  not  of  very  infrequent  occurrence  among  children,  and  are  as  in- 
teresting to  the  dermatologist  as  they  are  hai-mless  to  the  patient.  The  affection  commonly 
attacks  children,  and  the  face  and  neck  is  its  most  common  seat.  The  tumors  exhibit  a 
tendency  in  many  cases  to  congregate  about  the  eyes,  and  occasionally  about  the  mouth.  I 
have  met  with  them  exceptionally  upon  the  scalp,  ears  and  tip  of  nose.  In  adults  the 
genital-s  are  the  part  usually  affected,  although  the  mollusca  sometimes  occur  on  nearly  all 
parts  of  the  body. 

Each  individual  tumor  is  of  slow  development  and  indefinite  duration.  It  begins  as  a 
pin-head  sized  whitish  elevation  in  the  epidermis,  with  a  minute  central  depression,  which 
becomes  more  i)rominent  as  the  growth  increases  in  size.  When  it  is  as  large  as  a  hemp-seed 
the  summit  becomes  flattened,  the  base  more  or  less  constricted,  the  centre  of  the  growth 
appears  whiter  than  the  wall  of  the  tumor,  which  is  usually  of  normal  skin-color,  and  lateral 
pressure  causes  a  whitish,  cheesy  substance  to  exude.  Under  the  microscope  this  is  found  to 
be  composed  mainly  of  peculiar  round  or  oval  bodies  known  as  the  "molluscum  corpuscles." 
The  tumors  have  usually  a  waxy,  transparent  aspect,  although,  when  they  have  attained  the 
size  of  a  large  pea,  the  walls  are  often  traversed  by  fine  blood-vessels,  and  present  a  pinkish 
appearance.  No  pain  or  other  subjective  sensation  accompanies  the  growth,  which  may 
persist  for  a  year  or  more,  never  getting  larger  than  a  large  pea,  and  finally  withering  or  un- 
dergoing a  process  of  destructive  inflammation. 

In  a  large  proportion  of  cases  the  hands  of  the  patient  wUl  be  found  to  be  the  seat  of 
ordinary  warts. 

Tin-  etiology  of  molluscum  is  obscure.     Its  occurrence  in  several  members  of  one  family, 

(124) 


MOLLUSC  UM. 

and  the  fact  that  it  has  been  observed  to  aSect  suddenly  a  number  of  children  in  a  hospital 
ward,  have  led  to  a  belief  in  its  contagious  nature.  But  this  is  by  no  means  proven.  Al- 
though the  disease  occurs  with  much  greater  frequency  among  the  poorer  classes,  it  cannot 
be  considered  as  the  offspring  of  poverty  and  uncleanliness.  Damp  and  crowded  dwellino^ 
may  favor  its  development,  and  I  have  known  a  number  of  cases  to  occur  in  such  a  locality. 
HI  health  is  not  always  a  factor  in  its  production,  for  while  most  of  the  molluscous  children 
I  have  exanuned  were  strumous  or  weakly,  there  have  been  Home  upon  whose  faces  not  even 
the  dirt  could  conceal  the  glow  of  health. 

Diagnosis.  The  diagnosis  is  very  simple,  the  tumors  being  so  peculiar  ia  appearance 
that,  when  once  seen  and  recognized,  they  could  hardly  be  mistaken  when  met  with  a  second 
time.  I  have  seen  numerous  mollusca  upon  the  face  of  a  young  woman,  which,  on  account 
of  their  whitish,  flattened  summits  and  central  depression,  bore  a  striking  resemblance, 
when  observed  at  a  distance,  to  the  umbilicated  pustules  of  variola.  A  mistake  in  diagnosis, 
however,  could  scarcely  occur. 

Fibromata,  when  small,  might  be  mistaken  for  mollusca,  and  especially  as  the  sebaceous 
glands  in  the  former  tumors  frequently  contain  an  accumulation  of  sebum,  which  can  be 
pressed  out  in  the  form  of  cheesy  threads.  They  do  not  present,  however,  a  central  depres- 
sion, do  not  occur  in  groups,  do  not  have  the  plump  feeling  of  mollusca,  but,  on  the  other 
hand,  are  apt  to  be  quite  flaccid,  and  finally,  when  multiple,  as  they  usually  are,  they  vary 
considerably  in  size,  and  usually  become  much  larger  than  mollusca. 

Teeatment.  The  treatment  of  molluscum  is  simple,  the  object  beiQg  to  remove  the 
excrescence  and  to  excite  as  little  inflammation  as  possible  in  so  doing.  "When  the  mollusca 
are  so  situated  as  to  admit  of  abscission,  the  most  advisable  plan  of  treatment  is  to  shavt 
them  off  with  a  razor,  or  a  long,  thin-bladed  knife,  at  a  level  with  the  surrounding  skin. 
The  hemorrhage  occasioned  scarcely  amounts  to  more  than  a  drop,  and  it  is  quickly  checked 
by  touching  the  freshly-cut  surface  with  nitrate  of  silver.  When  the  mollusca  are  not 
seated  upon  a  projecting,  or  at  least  upon  a  convex  part,  but  occur  ia  certain  localities, 
where,  especially  in  the  case  of  struggling  children,  a  knife  could  not  be  handled  with 
safety,  a  pair  of  curved  scissors  may  be  used  in  its  stead.  For  very  small  mollusca,  nothing 
more  than  slight  cauterization  is  required  to  arrest  their  growth  and  to  hasten  their  disap- 
pearance. They  may  be  bored  very  gently  with  a  conical  stick  of  nitrate  of  sUver,  or  touched 
with  a  fine  glass  rod  dipped  Lu  strong  acetic  acid.  When  a  cluster  of  tumors  have  coalesced 
and  undergone  a  process  of  destructive  inflammation,  the  hard  crust  should  be  removed  by  a 
poultice  or  dressing  of  cosmoline,  and  a  little  balsam  of  Peru  applied  to  heal  the  superficial 
ulceration.  When  a  molluscum,  however  large,  is  removed,  no  scar  is  left,  imder  ordinary 
circumstances,  since  the  growth  is  epidermic  in  character,  and  can  scarcely  be  said  to  involve 
the  coriumor  true  skin.  When  an  inflamed  molluscum  is  scratched  or  irritated  to  the 
degree  of  purulent  secretion,  a  sUght  pit  may  be  expected  to  result.

DISEASES  OF  THE  SKIN— HYPERTROPHIC. 


CORNUA  CUTANEA. 

In  medical  literature  we  find  many  accounts  of  human  horns  springing  from  various 
portions  of  the  body.  These  cases  create  surprise  and  wonder  at  first  thought,  but  when 
we  consider  that  the  outer  layer  of  the  epidermis,  together  with  the  nails,  is  a  natural  gro\Arth 
of  homy  character,  we  become  far  less  surprised  by  these  unnatural  homy  growths.  The 
favorite  seat  of  horns  may  be  said  to  be  the  head,  although  there  is  scarcely  a  portion  of  the 
whole  body  which  has  been  spared.  They  have  been  reported  as  occurring  on  the  scalp, 
forehead,  temple,  nose,  cheek,  lip,  jaw,  breast,  back,  pubes,  glans  penis,  scrotum, 
prseputium  clitoridis,  thigh,  knee,  leg,  hand  and  foot.  Though  usually  occurring  in  the  aged, 
they  have  been  met  with  in  young  children.  In  size  and  shape  they  vary  considerably,  some 
being  short  and  stumpy,  others  conical,  and  many  long,  curving  and  somewhat  spiral. 
Rayer  mentions  the  case  of  an  old  woman  with  a  conoidal  horn  springing  from  the  forehead, 
which  was  six  or  seven  inches  in  diameter  at  the  base,  and  which  projected  six  inches. 
Nayler  speaks  of  a  horn  ten  inches  in  length,  and  curved  like  a  ram's  horn.  The  shorter 
horns,  with  a  rounded  extremity,  are  usually  thicker  at  the  base  than  those  of  greater  length. 
The  long  ones  are  always  curved  when  a  few  inches  in  length,  and  often  twisted.  The  sur- 
face is  always  rough,  and  usually  ridged  transversely.  When  of  a  marked  homy  character 
the  horn  may  present  longitudinal  striae,  and  show  a  tendency  to  split  in  this  direction.  The 
color  of  a  horn  varies  from  a  yellowish  to  a  dark  brown  or  blackish  hue,  and  is  lighter  at  the 
apex  than  at  the  base.  The  consistence  of  the  growth  also  varies,  some  horns  being  soft  and 
friable,  and  others  quite  dense.  The  outer  portion  is  always  harder  than  the  inner.  The 
base  of  a  horn,  like  the  base  or  youngest  i)ortion  of  a  nail,  is  often  surrounded  vnth.  a  thin 
layer  of  epidermis.  "When  removed,  the  horn  presents  a  conical  cup-like  depression,  which 
fits  over  a  fungoid  mass  projecting  above  the  level  of  the  skin  ^Vhen  cut  across,  it  may  be 
found  to  be  cylindrical  or  flattened  from  side  to  side.  Microscopical  examination  shows  it 
to  be  composed  chiefly  of  epidermic  cells,  usually  arranged  in  a  concentric  manner.  Tlie 
horn  may  spring  from  the  free  surface  of  the  skin,  or  originate  in  one  of  the  larger  se- 
baceous follicles.  It  may  therefore  be  regarded  as  being  either  an  exaggerated  wart,  having 
a  soft,  pulpy,  papillomatous  base,  surmounted  by  a  cone  of  dense  epidermis,  or  as  being  a 
dried  and  hardened  sebaceous  or  epidermic  mass,  which  derives  its  shape  from  being  slowly 
extruded  from  a  sebaceous  cyst.  In  some  cases  the  nail,  especially  that  of  the  great  toe, 
becomes  greatly  thickened  and  rounded  and  finally  assumes  the  shape  and  other  character- 
istics of  a  horn. 

Cutaneous  horns  develop  slowly,  and  are  painless  when  unirritated.  The  base  may  be- 
come infiamed  from  injury  done  to  it  by  violent  movement  of  the  growth.  A  horn  may 
continue  to  grow,  whatever  size  it  has  attained,  but  the  longer  it  is,  the  greater  is  its  liability 
to  become  accidentally  knocked  or  tom  off.  When  it  falls  in  this  way,  or  is  merely  cut  off 
on  a  level  with  the  surrounding  skin,  the  growth  is  reproduced,  and  a  succession  of  horns 
may  occupy  a  given  site.     Not  infrequently  two  horns  take  the  place  of  a  preceding  one.

ICHTETOSIS. 

Diagnosis.  The  diagnosis  of  a  case  is  easy  when  the  horn  is  present.  Before  the  horn 
has  formed  or  after  it  has  been  removed  the  cutaneous  lesion  bears  a  resemblance  to  a  nodule 
or  an  ulcerated  patch  of  lupus.  The  base  from  which  it  springs  might  be  mistaken  for  an 
epithelioma  or  malignant  growth  of  some  kind.  On  the  lip,  indeed,  epithelioma  has  been 
observed  to  follow  a  horny  growth. 

Treatment.  The  treatment  called  for  in  the  case  of  a  cutaneous  horn  consists  in  not 
only  removing  the  growth,  but  destroying  the  base  from  which  it  springs,  in  order  to  prevent 
its  reproduction.  The  horn  itself,  being  frequently  quite  movable,  can  readily  be  torn  from 
the  skin  with  a  slight  amount  of  violence,  especially  when  the  part  has  been  previously 
softened.  The  base  should  now  be  scraped  with  the  curette,  and  cauterized  lightly  with 
caustic  potassa  or  the  chloride  of  zinc.  This  will  produce  a  radical  cure,  and  leave  but  a 
trifling  scar  in  the  place  of  the  unsightly  excrescence.  When  the  horn  springs  from  a  dis- 
tended follicle  or  cyst,  extirpation  of  this  with  the  horny  growth  is  usually  recommended. 

ICHTHYOSIS. 

Synonym — Fish-skin  or  Alligator  disease. 

Ichthyosis  is  a  chronic  disease  of  the  skin,  characterized  by  dryness  and  roughness.  It 
varies  in  severity  from  cases  in  which  the  abnormal  condition  of  the  skin  is  so  slight  as  to 
be  perceptible  to  the  touch  rather  than  to  the  eye,  to  cases  in  which  large  polj'gonal  scales 
or  blackened  horny  projections  take  the  i)lace  of  the  normal  epidermis.  This  variable  de- 
gree of  severity  has  led  to  a  division  of  the  disease  into  the  forms  to  which  the  names  xero- 
derma, ichthyosis  simplex,  and  ichthyosis  hystrix  have  been  applied.  These  terms  are 
convenient  for  descriptive  purposes,  but  it  should  not  be  inferred  that  xeroderma  and  ichthy 
osis  are  distinct  affections.  Nor  is  ichthyosis  hystrix  to  be  understood  as  meaning  anything 
but  a  peculiar  form  of  ordinary  ichthyosis. 

In  the  mildest  cases  of  the  disease,  very  frequently  observed  in  infants  and  young  chil. 
dren,  there  is  a  deficiency  of  the  sebaceous  secretion  as  well  as  of  perspiration  and  a  harsh 
or  mealy  condition  of  the  epidermis.  The  skin  is  a  trifle  darker  than  normal,  and  suggests 
the  idea  of  a  lack  of  soap  and  water.  In  other  cases,  or  in  these  same  cases  at  a  later  period, 
the  epidermis  becomes  hypertrophied,  and  cracks  in  a  characteristic  manner.  Small  lozenge- 
shaped  or  pentagonal  scales  result,  which  are  slightly  raised  at  their  margins.  In  a  more 
severe  or  further  advanced  condition  these  hypertrophied  epidermic  plates  become  darker  in 
color,  and  assume  a  yellowish  or  greenish  hue,  while  the  furrows  between  them  appear  like 
a  network  of  white  interlacing  lines.  The  plates,  though  horny  and  sometimes  glistening, 
are  never  found  lapping  one  over  another,  as  might  possibly  be  inferred  from  the  name  of 
the  disease  or  its  common  synonym  of  "fish-skin  disease."  In  cases  of  unusual  severity 
one  or  more  patches  of  skin  may  become  covered  with  black  papillary  projections,  presentiug 
an  appearance  which  is  suggestive  of  the  bark  of  a  tree.     These  patches  are  similar  to  those 

(127) 


DISEASES  OF  THE  SKIN.—EYPERTROPEW. 

warty  growths  whicli  appear  upon  the  skin  in  elephantiasis.  When  these  papillary  projec- 
tions, which  are  always  thickly  crowded  together  and  usually  ilattened,  become  elongated 
and  pointed,  the  term  ichthyosis  hystrix  has  been  applied  to  the  condition,  from  the  fancied 
resemblance  of  the  spines  to  the  quills  of  a  porcupine.  Cases  presenting  this  form  of  the 
disease  have  been  on  exhibition  as  "Porcupine  men." 

Dr.  L.  P.  Yandell  has  reported  {Louisville  Med.  News,  1878,)  an  interesting  case  of  ich- 
thyosis, which  was  on  public  exhibition  as  the  "Man-fish  of  Tennessee."  Represented  a 
magnificent  example  of  the  form  of  the  disease  which  has  been  called  Ichthyosis  serpentina, 
the  resemblance  of  his  skin  to  the  skin  of  a  boa-constrictor  being  almost  perfect.  About  his 
joints  the  skin  was  loose  and  wrinkled.  Upon  the  belly  and  limbs  the  scales  were  large  and 
suggestive  of  the  skin  of  a  lizard  or  alligator.  The  cuticle  was  everywhere  dry  and  hard 
and  there  was  no  perspiration.  The  man  was  fifty  years  of  age,  but  being  shrunken  and 
withered  he  appeared  like  a  very  old  man.  The  skin  of  the  face  was  red  and  shining  and 
tightly  drawn  about  the  cheeks,  pulling  the  lower  lids  do^^-n  to  such  an  extent  as  to  perfectly 
evert  them  and  making  a  horrid  case  of  Ectropion.  The  fingers  and  toes  seemed  shorter 
than  natural  and  the  separation  between  them  extended  much  further  down  than  usual,  sug- 
gesting a  webbed  condition.  He  was  the  father  of  several  children,  none  of  whom  inherited 
the  disease. 

Another  striking  case  of  the  aflEection  was  lately  on  exhibition  in  this  city  under  the  name 
of  the  "Alligator  Boy."  Two  excellent  colored  lithographs  of  this  child  will  be  found  in 
the  Journal  of  Cutaneous  and  Venereal  Diseases  (April,  1884).  At  the  Skin  Clinic  of  the 
CoUege  of  the  Physicians  and  Surgeons,  the  following  brief  notes  were  taken : 

At  birth  the  child  weighed  four  and  one-half  pounds  and  presented  an  ichthyotic  con- 
dition, which  has  since  increased  in  severity.  When  about  a  year  old,  the  frontal  epidermis 
split  vertically  in  the  centre  of  the  forehead  and  was  cast  off  in  two  lateral  pieces.  The 
hands  at  this  time  "looked  like  those  of  a  ninety-year  old  man."  The  boy  had  never  had 
any  of  the  acute  exanthemata,  or  severe  illness  of  any  sort ;  and  in  spite  of  the  fact  of  his 
spending  the  most  of  his  time  in  the  close  atmosphere  of  the  show  room,  he  was  said  to  be 
far  less  delicate  than  one  would  judge  by  his  appearance.  The  muscles  of  the  lower  extrem- 
ities were  not  at  all  developed,  and  he  was  scarcely  able  to  stand  alone.  By  means  of  his 
arms,  he  would  creep  across  the  floor  quite  readily,  and,  according  to  the  father's  statement, 
could  not  only  swim  like  his  namesake,  but  had  an  uncontrollable  desire  to  get  into  the  water 
whenever  an  opportunity  offered.  He  had  a  good  appetite,  and  was  especially  fond  of  fish, 
oysters,  and  the  whites  of  eggs.  He  liked  fruit,  but  ate  no  meat,  and  I  was  assured  that  his 
bowels  rarely  moved  oftener  than  once  in  two  weeks. 

The  eruption,  contrary  to  the  rule  in  ichthyosis,  was  most  marked  upon  the  trunk,  the 
epidermis  being  broken,  by  the  movements  of  the  body,  into  polygonal  horny  plates  of  vary- 
ing size,  and  of  a  dirty  yellowish  hue.  In  the  intervening  fissures,  the  pinkish  color  of  the 
deeper  skin  was  apparent.  The  scalp  and  forehead  were  also  affected  in  a  marked  degree. 
Tlie  rest  of  the  face  was  free  from  scales,  save  a  slight  mealy  o'7ndition  around  the  nose  and

ICHTHYOSIS. 

moutli,  and  the  cheeks  were  as  smooth  and  soft  as  those  of  any  child.  The  arms  were  but 
slightly  affected,  and  the  fore-anns,  especially  upon  the  extensor  aspect,  were  almost  natural 
in  appearance.  The  legs  also  were  almost  free  from  scales.  The  parents  stated  that  in 
winter  the  sMn  upon  the  trunk  was  smooth,  though  horny  in  character.  In  the  spring  this 
homy  integument  was  wont  to  crack  and  present  the  characteristic  "alligator"  appearance, 
while  the  hair  of  the  head  was  almost  entirely  shed.  In  the  summer  the  scales  would  grad- 
ually lessen  and  the  skin  become  much  softer,  though  by  no  means  normal. 

This  boy  was  bom  in  Montreal,  in  May,  1879,  and  Dr  F.  Kennedy,  who  officiated  at  his 
dM)ut,  has  kindly  furnished  me  with  the  following  information.  The  mother  was  a  primi- 
para,  and  claimed  that  it  was  impossible  for  her  to  have  been  more  than  eight  months  preg 
nant  at  the  birth  of  her  chUd.  At  four  and  one-half  months  (according  to  her  statement  to 
me),  she  was  frightened  at  the  sight  of  an  alligator,  and,  a  few  weeks  later,  by  seeing  a  dog 
ia  a  fit.  A  tedious  and  irregular  labor  was  followed  by  natural  delivery.  At  birth,  the  child 
presented  a  most  extraordinary  appearance.  The  skin  was  thicldy  covered  -s^-ith  vernix 
caseosa,  and,  when  washed,  the  surface  was  as  smooth  as  if  polished,  and  of  a  deep  red 
color.  In  fact,  the  surface  had  the  appearance  of  being  thickly  varnished.  There  were 
very  few  fissures  noticeable,  and  so  strong  was  the  coating  that  it  was  impossible  for  the 
child  to  make  use  of  its  facial  muscles  in  its  efforts  to  cry  or  suck.  Its  limbs  were  also  res- 
tricted in  their  movements.  After  a  few  days,  fissures  occurred  more  especially  along  the 
facial  lines.  On  the  forehead  were  two  large  scales  separated  along  the  median  line.  On 
the  eyelids,  cheeks,  and  around  the  mouth,  armor-like  scales  were  formed.  On  the  back  the 
scales  were  very  thick.  There  was  no  healthy  skin,  as  the  whole  surface  was  more  or  less 
covered  with  scales.  The  skin  was  thoroiaghly  smeared  with  cod-liver  oil,  and  the  same, 
with  iodide  of  iron,  was  given  internally.  Under  this  treatment  considerable  improvement 
was  obtained.  About  the  second  week  the  scales  loosened  and  peeled  off,  and  about  the  fifth 
week,  the  skin,  with  the  exception  of  the  face,  had  become  soft  and  pliable,  though  still  of 
a  deep  red  color  and  shiny. 

The  above  case  may  be  regarded  as  a  connecting  link,  in  point  of  severity,  between 
ordinary  cases  of  congenital  ichthyosis  and  certain  cases  which  have  been  reported  by  Kyber, 
Wheelock  and  others,  as  diffused  congenital  keratoma.  In  these  cases,  the  integument 
appears  as  one  immense  homy  plate,  of  a  dirty  yellowish  hue,  or  if  this  is  broken  during  the 
delivery  of  the  child,  the  fissures  formed  reveal  a  bright  red  underlying  skin.  These  cases 
usually  die  at  birth,  or  shortly  after,  and  may  be  regarded  as  the  most  severe  form  of  con- 
genital ichthyosis. 

Ichthyosis  affects  the  greater  portion  of  the  skin.  The  palms  and  soles  are  always  free 
from  scales,  although  the  epidermis  may  be  considerably  thickened.  The  flexures  of  the 
joints  are  usually  devoid  of  scales,  although  abnormal  dryness  of  the  skin  is  always  present. 
Around  the  elbows  and  knees  the  epidermis  is  broken  up  into  smaller  plates,  and  numerous 
elliptical  wrinkles  or  folds  of  skin  occupy  these  parts.  The  disease  usually  begins  in  infancy 
and  never  in  adult  Ufe.      In  the  majority  of  cases  the  mUd  or  xerodermatous  form  tends  to 

(129) 


DISEASES  OF  TEE  SRIN—ETFERTROPHIO. 

remain  through  life,  while  in  some  instances  the  affection  increases  in  severity  from  year  to 
year.  It  is  sometimes  hereditary.  Two  or  more  children  in  one  family  may  be  affected, 
while  others  in  the  same  family  show  no  tendency  whatever  to  the  affection.  It  is  attended 
with  little  or  no  discomfort  beyond  the  consciousness,  on  the  part  of  the  patient,  that  his 
skin  is  not  what  it  should  be,  and  it  exerts  no  influence  on  the  patient' s  general  health. 
Wild  cases  are  often  temporarily  cured  in  hot  weather,  when  the  perspii'atory  glands  are 
active,  and  even  the  most  aggravated  cases  are  considerably  better  in  summer  than  in  ^vinter. 
In  the  latter  season  ichthyotic  patients  usually  suffer  considerably  from  the  cold,  and  when 
exposed  to  high  winds  the  face  and  hands  are  unusually  prone  to  become  chapped  and 
painful. 

Diagnosis.  The  diagnosis  of  the  disease  is  easy  when  its  extensive  distribution  ove>" 
the  body,  the  absence  of  redness  and  itching  and  its  chronicity  are  taken  into  account. 
Pityriasis  simplex  is  the  only  affection  to  which  it  bears  any  resemblance,  but  in  pityriasis 
the  skin  is  not  so  generally  affected,  there  is  hypersemia  beneath  the  scales,  and  these  are 
constantly  falling,  or  are  easily  rubbed  off,  while  in  ichthyosis  there  is  no  hyperjemia,  and 
the  scales  remain  upon  the  skin. 

Treatment.  The  treatment  of  ichthyosis,  or  at  least  its  cure,  is  not  easy.  The  skin  may 
be  made  quite  smooth  by  appropriate  applications,  but  as  soon  as  these  are  laid  aside,  the 
roughening  and  scaling  tend  quickly  to  reappear.  Inunction  is  the  chief  remedy  in  the 
treatment  of  mild  cases.  Cosmoline,  vaseline,  benzoated  lard,  almond,  linseed  and  cod-liver 
oils  are  useful,  and  as  each  accomplishes  the  object  in  view,  viz.,  the  lubrication  of  the  pre- 
tematurally  dry  skin,  it  matters  little  which  one  is  selected.  Balmanno  Squire  thinks  tliat 
glycerine  diluted  with  three  times  its  quantity  of  water  is  more  effectual  than  oil  in  keeping 
the  skin  in  good  condition. 

In  severe  cases,  where  the  epidermic  plates  are  thick  and  homy,  inunction  may  still  be 
advantageously  employed,  but  greater  dependence  must  now  be  placed  upon  soap  frictions 
and  constant  bathing.  Some  patches  on  the  extensor  surface  of  the  extremities  may  be  so 
hard  as  to  require  blistering.  The  Turkish  bath  renders  excellent  service  in  all  cases  of  ich- 
thyosis. The  profuse  sweating  is  useful,  as  is  shown  by  the  improvement  which  naturally 
takes  place  in  hot  weather,  and  the  shampooing  removes  the  superfluous  epidermis.  The 
body  should  be  thoroughly  anointed  after  each  bath.  Jaborandi  has  been  given  internally 
in  this  affection,  and  has  produced  a  rapid  improvement  in  the  condition  of  the  skin,  but 
there  are  objections  to  the  use,  and  the  Turkish  bath  is  to  be  preferred. 

KERATOSIS  PILARIS. 

Synonym — Lichen  Pilaris. 

An  accumulation  of  epidermic  cells  in  the  hair  follicles  produces  numerous  fine  papules 
upon  the  surface  of  the  skin,  and  constitutes  the  affection  kno\vn  as  keratosis  pilaris.  Ordi- 
narily these  are  dry,  whitish  horny  elevations,  thicldy  crowded  together,  and  giving  the  skin 

(130) 


MO  RFHCEA.-^SCLERO  DERMA. 

a  rough  and  harsh  appearance,  but  frequently  they  become  inflamed  at  their  base  and  the 
skin  is  then  studded  with  small  pin-head  sized,  conical  red  papules,  each  of  these  is  usually 
perforated  by  a  fine  lanugo  hair,  showing  the  lesion  to  originate  within  the  follicles. 

The  affection  is  also  noticed  on  the  extensor  aspect  of  the  extremities,  especially  on  the 
forearms  below  the  elbows.  Frequently  the  outer  aspect  of  the  thighs  and  buttocks  are  its 
seat. 

It  usiially  causes  no  special  inconvenience  and  often  exists  for  years.  In  certain  cases 
however,  the  affection  becomes  quite  marked  upon  the  extremities,  is  accompanied  by  more 
or  less  itching  and  thus  induces  the  patient  to  seek  medical  aid. 

The  cause  of  the  affection  is  sometimes  a  lack  of  cleanliness  or  undue  attention  to  the 
hygiene  of  the  skin.  This  may  be  the  case  when  there  is  a  simple  accumulation  of  epidermis 
in  the  follicles,  but  often  there  is  an  excessive  growth  of  the  epidermis  which  frequent  ablu- 
tions do  not  check.  This  is  almost  invariably  associated  with  a  general  dryness  of  the  skin. 
The  affection  is  met  with  in  youth  and  middle  age,  and  is  perhaps  a  little  more  frequent 
among  females. 

Teeatjient.  In  mild  cases  of  keratosis  pilaris  daily  friction  with  green  soap  will  suf- 
fice to  remove  the  horny  prominences  and  leave  the  skin  comparatively  smooth.  In  cases 
where  a  large  extent  of  surface  is  involved  frequent  warm  baths  containing  potash  or  soda, 
and  daily  inunction  with  oil  or  fluid  cosmoline  are  admirable.  The  general  health  should  be 
improved  as  far  as  possible,  and  when  a  sluggish  circulation  and  inactivity  of  the  sweat 
glands  are  noticed  the  Turkish  bath  is  the  best  remedy  that  can  be  prescribed 

MORPHCE  A. -SCLERODERMA . 

It  is  convenient  to  speak  of  morphoea  and  scleroderma  together,  as  there  is  a  kinship 
between  the  two  affections,  and,  according  to  several  writers,  a  pathological  identity.  Bui 
whether  they  are  forms  or  stages  of  the  same  disease  or  not,  a  clinical  differentiation  is  gen- 
erally easy,  and  until  a  fuller  knowledge  of  their  nature  has  been  acquired,  it  appears  advisa- 
ble to  retain  both  terms  in  use. 

Morphoea  is  a  circumscribed  affection.  When  first  noticed  there  are  usually  one  or  more 
round  or  oval  whitish  patches  of  skin,  with  a  faintly  marked  border  of  a  darker  hue.  "When 
multiple,  these  patches  vary  in  size,  and  are  usually  distributed  along  the  course  of  a  nerve. 
They  increase  but  slowly  in  size,  and  assume  an  alabaster  whiteness  or  a  dull  creamy  tint, 
which  has  been  aptly  compared  to  the  color  of  an  old  billiard  ball.  They  are  seldom  raised, 
but,  on  the  contrary,  they  may  be  slightly  depressed  below  the  surface  of  the  skin,  and 
appear  atrophic  in  character.  The  surface  may  be  smooth  and  waxy,  or  roughened  by  nu- 
merous fine  wrinldes,  which  give  to  it  a  peculiar  shriveled  appearance.  Sometimes  a  patch 
is  quite  firm  to  the  touch,  although  the  hardness,  when  present,  is  always  superficial.  On 
the  other  hand,  it  may  differ  little  to  the  touch  from  the  surrounding  normal  sldn.  The  nar- 
row border  fi-equently  assumes  a  dull  red  or  lilac  hue,  and  constitutes  a  conspicuous  feature 

(131) 


DISEASES  OF  THE  SKIN—ETPERTROPHIC. 

of  the  affection.  Dark  macules  of  a  similar  tint  are  often  noted  as  preceding  the  develop- 
ment of  the  smal.  white  patches.  The  affection  is  most  common  on  the  extremities,  though 
met  with  on  tlie  neck  and  trunk.  There  is  no  pain  or  discomfort  produced  by  the  presence 
of  the  patches,  and  after  a  lapse  of  years  they  may  tend  to  disappear  spontaneously. 

Scleroderma  is  a  diffused  induration  of  a  tract  of  skin  and  its  subjacent  connective  tissue. 
The  affected  part  at  first  becomes  stiff,  and  later  assumes  a  certain  density  and  tension, 
which  is  well  expressed  by  the  term  "hide-bound."  The  skin  itself  presents  no  lesions  to 
the  eye,  save  in  some  cases  a  decided  pigmentation.  The  affected  part  may  appear  shrunken, 
but  the  peculiarity  of  the  affection  is  best  revealed  to  the  touch.  There  is  usually  no 
margin  to  a  patch  of  scleroderma.  The  hardness  gradually  shades  off  into  the  surrounding 
normal  skin.  Large  tracts  of  skin  are  often  involved  by  the  disease — the  whole  side  of  a 
limb,  for  example.  Like  morphoea,  it  progresses  slowly,  lasts  indefinitely,  and  in  rare  in 
stances  subsides  spontaneously. 

From  the  above  brief  description  a  striking  difference  is  seen  to  exist  between  tjT)ical 
cases  of  morphoea  and  scleroderma.  But  in  some  cases  the  patient  presents  lesions  charac- 
teristic of  each  affection.  The  diagnosis  is  consequently  uncertain,  and  the  conviction  is 
foscered  that  the  two  affections  are  identical  in  nature.  Both  morphoea  and  scleroderma 
h*"  ve  been  observed  more  frequently  in  women  than  in  men.  Cases  occur  infrequently  in 
0^  ildhood.  No  known  cause  exists,  and  the  patient  affected  may  in  other  respects  appear  in 
'  verage  health. 

Diagnosis.  Morphoea,  in  its  incipient  stage,  is  to  be  distinguished  from  scleroderma, 
which  it  resembles.  The  marked  change  in  the  character  of  the  skin,  apart  from  its  mere 
loss  of  pigment,  and  the  partial  ansethesia  which  usually  exists,  are  points  of  diagnostic 
value.  The  whitish  anjesthetic  macules  which  sometimes  occur  in  leprosy  resemble  morphoea, 
but  their  nature  is  generally  revealed  by  the  co-existing  indications  of  the  leprous  diathesis. 
Scleroderma  can  hardly  be  confounded  with  other  cutaneous  affections.  It  should  be  re- 
marked, however,  that  there  exists  an  acute  affection  of  the  skin,  in  which  hardening  of  the 
integument  takes  place  rapidly  over  a  large  portion  of  the  body,  and  disappears  in  a  short 
time.  This  must  be  distinguished  from  scleroderma,  and  may  be  conveniently  called  scleri- 
nsis  or  sclerema,  the  latter  of  which  terms  has  been  usually  applied  to  a  similar  affection 
occurring  in  infants  (Sclerema  neonatorum). 

Treatment.  Little  benefit  is  to  be  expected  from  treatment  in  cases  of  morphoea  or 
scleroderma.  Under  arsenic  internally  and  the  local  application  of  the  constant  galvanic 
current  there  seems  to  be  the  best  prospect  of  achieving  success.  The  use  of  the  galvanic 
battery  in  cases  of  scleroderma  has  been  followed  by  very  good  results.  The  progress  of 
these  affections  Ls  slow  and  the  prognosis  is  uncertain.  A  marked  improvement,  if  not  a 
perfect  cure,  is  always  a  possibility,  and  since  the  local  condition  is  more  or  less  dependent 
upon  the  general  health  of  the  patient,  nothing  in  the  shape  of  tonic  and  hygienic  treatment 
should  be  neglected.

ELEPRANTIAS18. 


ELEPHANTIASIS. 

Synonyms — Lepra  Arabmn — Barbadoes  Leg. 

Elephantiasis  is  a  disease  wMch  is  entirely  distinct  from  leprosy.  Hitherto  much  confu- 
sion has  been  occasioned  by  the  use  of  the  terms  Elephantiasis  Arabum  to  designate  the  dis- 
ease under  consideration,  and  Elephantiasis  Grrgecorum  to  designate  leprosy.  These  qualify- 
ing adjectives  have  now  been  pretty  generally  discarded  in  this  country,  and  while  the  term 
lepra  is  applied  to  leprosy,  the  term  elephantiasis  is  employed  solely  in  connection  with  the 
elephantine  disease. 

This  disease  consists  in  a  hypertrophic  growth  of  skin  and  sab-cutaneous  tissue,  and 
affects  chiefly  the  lower  extremities  and  genitals.  The  leg  and  foot  are  most  frequently 
attacked.  It  is  unusual  for  the  disease  to  extend  above  the  knee,  and  extremely  rare  for  both 
lower  extremities  to  be  wholly  affected,  as  in  the  remarkable  case  portrayed  in  the  illustra- 
tion. Cases  have  been  reported  of  the  disease  occurring  upon  the  cheeks,  breast  and  upper 
extremities.  Fibromatous  tumors  and  that  peculiar  relaxed  condition  of  the  skin  known  as 
Dermatolysis  or  Cutis  pendula  may  occur  upon  those  parts  and  assume  elephantine  propor- 
tions, but  they  are  to  be  carefully  distinguished  from  true  elephantiasis. 

The  disease  is  chronic  in  its  course,  does  not  affect  the  health  in  any  marked  degree,  and 
the  patient  suffers  principally  from  interference  with  locomotion,  depending  iipon  the  weight 
of  the  affected  limb.  It  is  met  with  in  all  parts  of  the  world,  but  abounds  in  tropical  cli- 
mates, where  it  attacks  by  preference  those  whose  constitutions  have  been  impaired  by  im- 
proper diet,  excessive  exposure  and  other  causes.  In  the  West  Indies  it  is  so  common  that 
Barbadoes  Leg  has  come  to  be  a  well-known  synonym. 

The  disease  is  intimately  connected  with  conditions  which  produce  obstruction  of  the 
lymphatics.  (Edema  plays  a  most  important  part  in  the  production  and  development  of  the 
disease,  and  recurrent  inflammatory  attacks  of  an  erysipelatous  nature  characterize  its  prog- 
ress. Each  attack  leaves  the  skin  more  swollen  and  harder,  and  the  attacks  continue  at  a 
variable  interval  until  the  part  affected  has  attained  an  immoderate  size.  The  scrotum,  for 
instance,  may  hang  nearly  to  the  floor  and  weigh  upwards  of  a  hundred  pounds.  In  the 
female  the  labia  and  clitoris  may  be  similarly  affected.  The  skin  of  an  affected  leg  is  dark- 
ened in  color  and  either  smooth  and  oedematous  or  fissured  and  scaly.  Its  sensibility  is  less- 
ened by  reason  of  the  great  thickening,  but  there  are  no  anaesthetic  patches  as  in  leprosy.  In 
severe  cases  portions  of  skin  become  pendulous  and  deep  creases  are  formed  between  them. 
Upon  the  dorsum  of  the  foot  and  anterior  aspect  of  the  leg  it  is  not  uncommon  for  the  skin 
to  present  a  verrucous  surface,  covered  with  dry  and  blackened  papillary  elevations.  Eczema 
often  appears  upon  the  surface  of  the  skin,  and  fissures  occur  at  the  bottom  of  the  furrows. 
Slight  ulceration  is  present  in  many  cases,  and  from  the  denuded  patches  a  large  quantity  of 
lymph  is  poured  out.  Sloughing  may  take  place,  especially  when  the  strength  has  failed 
and  the  patient  is  unable  to  leave  the  bed. 

(133) 


DISEASES  OF  THE  SKIN—HYFERTROPHIG. 

Diagnosis.  Elephantiasis  is  neither  contagious  nor  transmitted  through  hereditai  y  intlu . 
ences.  Its  causes  are  obscure,  but  are  doubtless  connected  mth  the  patient' s  manner  of  living. 
Malaria  has  been  cited  as  a  cause,  but  proof  is  lacking  as  to  its  influence.  Varicose  veins, 
cicatrices,  gummy  deposits,  bone  callus  and  other  local  conditions  inducing  obstruction  of  the 
venous  and  lymphatic  circulation  have  been  alleged  to  act  as  exciting  causes.  A  very  interes- 
ing  and  plausible  theory  has  been  advanced  that  the  disease  is  of  parasitic  origin,  and  that 
furthermore,  the  mosquito  is  responsible  for  its  existence.  Dr.  Manson,  a  British  surgeon 
resident  in  China,  has  discovered  the.  filar  ia  sanguinis  in  the  blood  of  elephantiasic  patients, 
as  also  in  the  blood  of  patients  affected  by  the  so-called  lymph-scrotum  and  chyluria.  He 
believes,  with  others,  that  this  parasite  has  its  habitat  in  the  lymphatics,  and  by  causing  ob- 
struction and  distal  fullness  of  these  vessels,  gives  rise  to  elephantiasis.  As  in  the  case  of 
tape-worm  ova,  the  immature ./^'arz«  can  only  become  developed  outside  of  the  human  body, 
and  the  mosquito  is  accused  of  being  their  intermediate  host.  In  the  stomach  of  this  insect 
the  undeveloped  tilaria  is  supposed  to  undergo  a  metamorphosis,  and  being  discharged  with 
the  young  of  the  mosquito  upon  the  water,  finds  its  way  into  human  lymphatics  and  occa- 
sions elephantiasis. 

Treatment.  The  treatment  of  this  disease,  though  often  gratifying,  is  not  always 
attended  with  the  desired  success.  In  the  early  stage,  rest,  poulticing  and  other  antiphlo- 
gistic remedies  should  be  employed  during  the  erysipelatous  attacks.  Later,  bandaging  is  of 
service,  as  it  tends  to  lessen,  though  seldom  permanently,  the  size  of  the  leg.  Hebra  recom- 
mended elevation  of  the  limb  and  inunction  of  mercurial  ointment.  Compression  and  liga- 
tion of  the  femoral  artery  have  been  practiced  in  a  number  of  cases  with  partial  success.  The 
improvement  which  follows  this  method  of  treatment  is  due  to  the  removal  of  arterial  pres- 
sure, which  interferes  with  the  functions  of  the  lymphatics.  This  pressure  being  removed, 
a  rapid  absorption  of  the  effused  serum  often  takes  place,  and  in  some  cases  the  decrease  of 
the  infiltration  is  permanent.  When  the  genitals  are  affected  in  a  marked  degree  the  knife 
is  the  remedy  most  in  vogue,  and  by  its  skillful  use  most  brilliant  results  have  been  achieved.

Rosacea  is  a  chronic  disease  of  the  middle  period  of  life,  occurring  upon  the  face,  and 
resulting  from  a  dilatation  of  blood-vessels  and  an  increased  growth  of  connective  tissue. 
Its  chief  features  are  redness  and  a  tendency  to  the  development  of  tubercles  and  pustules. 
The  affection  has  been  described  by  writers  on  dermatology  as  a  form  of  acne,  and  even  those 
who  have  believed  it  to  be  a  distinct  affection  have  generally  employed  the  term  Acne- Rosa- 
cea. Some  writers,  in  order  to  distinguish  the  affection  from  acne,  as  should  be  done,  have 
employed  the  old  but  expressive  term  Gutta  Rosea  or  Gutta  Rosacea.  Recently  rosacea  has 
been  disjoined  from  acne  in  name  as  well  as  in  nature,  and  this  usage  will  doubtless  tend  to 
dissipate  the  erroneous  idea  that  they  are  forms  of  the  same  disease.

BOSA  CEA. 

Rosacea  is  common  in  both  sexes  and  is  most  frequently  met  with  oetween  the  ages  of 
thirty  and  fifty.  Its  site  is  characteristic.  If  the  face  were  mapped  out  into  vertical  thirds 
the  middle  section  would  include  nearly  all  cases  of  rosacea.  The  parts  most  frequently 
affected  are  those  portions  of  the  cheeks  below  the  infra-orbital  ridges.  In  severe  cases  a 
fiery  triangle  may  be  seen  on  either  cheek,  lying  between  this  ridge  and  the  zygomatic  minor 
and  labio-nasal  muscles.  A  milder  form  of  the  disease  often  exists  upon  the  central  portion 
of  the  forehead,  just  above  the  bridge  of  the  nose,  and  at  a  shoi-t  distance  from  the  angles  of 
the  mouth  isolated  rosy  drops  are  frequently  observed. 

The  simplest  form  of  rosacea  is  that  which  appears  in  the  form  of  dull  red  macules  or 
slightly  elevated  papules,  resulting  from  chronic  congestion  or  dilatation  of  the  superficial 
vascular  plexus  around  the  mouth  of  a  follicle.  These  "rosy  drops"  sometimes  present  a 
central  point  of  a  somewhat  darker  hue,  more  elevated  and  at  times  surmounted  by  a  scale 
or  the  thin  crust  of  a  minute  pustule.  The  confluence  of  these  circular  "drops"  forms  a 
purplish-red  patch,  presenting  a  swollen  and  uneven  surface  dotted  with  patulous  follicles 
and  somewhat  resembling  the  skin  of  an  orange  in  texture.  As  the  disease  advances  the 
patch  becomes  studded  with  tubercles  which  usually  tend  to  suppuration.  The  rounded 
summit  of  the  tubercle  assumes  a  yellowish- white  appearance  and  a  minute  superficial  drop 
of  pus,  evacuated  when  the  patient  is  washing  or  mping  the  face,  gives  place  to  a  thin,  dark 
colored  crust.  In  many  of  the  tubercles  a  more  decided  form  of  suppuration  occurs  and  in 
a  case  of  long  standing  numerous  hemispherical  pustules  or  abscesses  are  accordingly  present. 
These  pustules  are  not  of  glandular  origin,  as  in  acne,  and  may  be  easily  distinguished  from 
true  acne  pustules  by  their  rounded  summits  and  the  absence  of  a  central  comedo.  Similar 
pustules  or  small  superficial  abscesses  not  unfrequently  occur  in  acne,  especially  in  the  indu- 
rated form,  and  are  not  connected  with  the  sebaceous  glands. 

Dilatation  of  the  superficial  blood-vessels,  though  commonly  occurring  in  rosacea,  is  not 
an  essential  element  of  the  disease.  Where  the  condition  is  marked,  as  it  often  is  upon  the 
wings  of  the  nose,  constituting  the  most  striking  feature  of  the  affection,  the  term  Rosacea 
caricosa  has  been  employed. 

The  most  remarkable  form  of  the  disease  is  that  Icnown  as  Rosacea  hyperrrophica.  It 
IS  a  late  stage  of  the  affection  and  occurs  chiefly  on  the  nose.  The  tumid  or  luTJipy  condition 
of  the  skin  which  is  characteristic  of  the  disease  in  its  common  form  becomes  exaggerated  to 
such  an  extent  that  the  nose  assumes  astonishing  proportions.  A  number  of  tumors  project 
from  the  sides  or  tip,  varying  in  size  from  a  large  pea  to  a  small  egg,  and  frequently  become 
pedunculated.  The  nose  may  attain  the  size  of  the  fist,  and  either  partiaUj-  obstruct  vision 
or  hang  down  in  front  of  the  mouth.  This  condition  is  fortunately  so  rare  as  to  constitute  a 
dermatological  curiosity. 

Treatment.  Rosacea  resembles  acne,  in  being  largely  dependent  upon  disturbance  of 
gastric  and  uterine  functions.  The  treatment  in  most  cases  consists  of  a  combination  ol 
internal  and  local  remedies.  To  achieve  success  with  the  former  we  must  ferret  out  aU  pre- 
disposing and  exciting  causes.     Abnormal  states  of  internal  organs  must  be  rectified.     Inju

rious  habits  must  be  abandoned  by  tlie  patient  and  strict  attention  paid  to  hygienic  rules. 
To  derive  benefit  from  local  applications  it  is  necessary  to  determine  the  amount  of  stimula- 
tion required  by  each  individual  case.  In  mild  cases,  where  there  is  much  irritability  and 
little  thickening  of  the  skin,  the  following  lotion  may  be  used  while  the  cure  is  being  effected 
by  internal  treatment :

When  there  is  marked  infiltration  of  the  skin  a  course  of  nightly  frictions  with  green 
soap  is  of  great  value.  Hard  nodules  upon  the  cheeks  which  remain  red  for  a  long  time 
without  suppuration  can  be  effectually  treated  by  electricity,  the  constant  current  being  used 
for  this  purpose.  Dilated  blood  vessels  may  be  well  scarified,  and  after  the  blood  has  ceased 
flowing  a  thick  coating  of  elastic  collodion  painted  over  them. 

A  still  better  mode  of  destroying  them  is  to  insert  a  fine  needle  connected  with  the  zinc 
element  of  a  galvanic  battery,  and  complete  the  circuit  by  touching  the  Jieighboring  skin 
with  a  sponge  tipped  electrode  connected  with  the  carbon  element.  In  the  hypertrophic 
form  of  the  disease  surgical  treatment  is  indispensable. 

HYPERTRICHOSIS. 
Synonyms — Trichauxesis — Hirsuties. 

An  abnormal  increase  in  the  growth  of  hair  may  be  conveniently  divided,  according  to 
Beigel,  into  three  classes. 

In  the  first  class  we  have  those  cases  in  which  the  naturally  hairy  parts,  e.  g. ,  the  scalp 
and  lower  portion  of  the  face,  become  the  seat  of  a  growth  of  hair  of  extreme  length. 
Many  readers  may  have  seen  on  exhibition  in  this  country  several  women  whose  luxuriant 
growth  of  hair  has  nearly  or  quite  reached  the  floor,  and  a  man  whose  long  sandy  beard 
would  have  to  be  lifted  to  prevent  his  treading  upon  it.  A  number  of  such  cases  are  on 
record,  as  also  one  of  a  woman  whose  pubic  hair  was  several  feet  in  length. 

In  the  second  class  of  cases  are  those  in  which  the  fine  lanugo  hairs  which  are  present 
over  the  greater  portion  of  the  skin,  become  large  and  moderately  long,  and  transform  a  man 
into  a  hairy  animal.  This  overgro\vth  of  hair  may  be  congenital  or  acquired.  Medical  litera- 
ture records  numerous  instances  of  children  who  have  been  born  with  a  hairy  skin,  and  the 

(136)

circumstance  has  usually  been  attributed  to  some  maternal  impression  occurring  during  preg 
nancy.  In  certain  cases  this  disposition  to  hirsuties  has  been  hereditary  and  transmitted 
through  several  generations,  and  it  is  noticeable  that  the  excessive  growth  of  hair  has  fre- 
quently been  associated  with  a  defective  development  of  the  teeth.  As  an  acquired  condition 
a  certain  degree  of  hairiness  is  often  noted  in  adolescence  and  adult  Ufe.  While  the  trunk 
and  limbs  of  some  men  appear  quite  hairless  at  a  short  distance,  others  rival  Esau  in  the 
abundant  growth  of  hair  upon  the  breast  and  elsewhere.  This  variation  appears  to  have  no 
more  connection  with  the  general  health  and  strength  than  has  the  varying  complexion  of 
the  skin.  A  temporary  growth  of  hair  over  the  body  has  been  noted  as  occurring  during 
convalescence  from  fever,  and  the  local  increase  of  growth  following  the  congestion  of  the 
skin  in  the  neighborhood  of  an  ulcer  is  very  common. 

To  this  class  of  cases  belong  the  hairy  moles  (Nsevus  pilosas),  which  are  always  congeni- 
tal when  of  large  size.  In  this  affection  the  lanugo  hairs  over  a  circumscribed  patch  of  skin 
are  abnormally  developed  and  associated  with  an  increased  deposition  of  pigment. 

The  third  class  of  cases  of  hypertrichosis  includes  the  women  and  children  who  present 
an  unusual  growth  of  hair  upon  those  parts  which  in  men  are  naturally  bearded.  Cases  of 
young  children  who  have  had  hair  upon  their  face  or  breast  have  been  reported,  but  they  are 
extremely  rare.  The  growth  of  hair  upon  the  female  face,  on  the  other  hand,  is  a  deformity 
which  is  very  frequently  observed.  Few  physicians  have  an  adequate  idea  of  its  prevalence. 
In  nearly  every  "museum  of  living  curiosities"  a  bearded  woman  figures  as  one  of  the 
chief  attractions.  There  are  at  least  a  half  dozen  of  this  class  now  on  exhibition  though- 
out  the  country.  Of  the  number  of  ladies  in  private  life  who  endeavor  by  artifice  of  various 
kinds  to  conceal  the  unpleasant  fact  that  they  have  or  might  have  a  beard,  it  would  be  very 
difficult  to  form  an  estimate.  I  have  no  doubt  that  there  are  many  hundreds  of  such  cases. 
I  speak  now  merely  of  those  who  might  raise  a  thick  and  long  growth  of  hair  which  would 
deserve  the  name  of  beard.  Of  those  who  have  a  comparatively  moderate  growth  of  hair 
upon  the  face,  the  number  is  beyond  computation.  The  upper  lip  is  most  frequently  affected 
to  a  slight  extent,  but  the  most  disfiguring  growth  occurs  upon  the  sides  of  the  chin.  The 
hairiness  may  be  strictly  limited  to  these  parts,  but  in  many  cases  it  is  seen  also  upon  the 
cheeks  and  sub-maxillary  region. 

The  cause  of  hypertrichosis  is  always  obscure,  and  perhaps  no  more  satisfactory  explana- 
tion can  be  given  of  its  occurrence,  whether  in  the  congenital  or  acquired  form,  than  the  asser- 
tion that  it  is  a  "  freak  of  nature."  I  have  sought  diligently  for  the  cause  of  facial  hairiness  in 
females  and  have  endeavored  to  find  some  characteristic  common  to  all  of  my  patients,  but 
in  vain.  Some  are  in  fine  physical  condition  while  others  are  debilitated.  Some  are  ex- 
tremely nervous.  Some  are  not  so  in  the  slightest  degree.  Some  are  stout  and  others  are 
thin.  Some  are  of  dark  and  others  of  light  complexion.  Some  are  maidens  ranging  from 
fifteen  to  fifty  years  of  age,  while  of  others,  who  are  married,  some  have  children  and  some 
have  none.  The  common  idea  that  the  growth  of  a  beard  in  a  female  is  usually  associated 
with  masculine  traits  of  character  is  certainly  not  founded  upon  fact,  for  most  of  my  patients 

(137) 


DISEASES  OF  THE  SKIN—HTFERTROPHIC. 

have  presented  the  very  highest  type  of  feminine  refinement.  That  facial  hairiness  is  depend- 
ent upon  a  malformation  or  imperfect  development  of  the  reproductive  organs,  as  some  have 
claimed,  appears  to  me  to  be  very  doubtful.  It  is  certain  that  an  intimate  relation  between 
these  two  conditions  has  not  been  satisfactorily  proven,  save  in  a  few  exceptional  cases. 

The  relation  of  facial  hairiness  in  females  to  derangement  of  the  nervous  system  is 
without  doubt  a  much  more  intimate  one.  The  depressed  mental  condition  which  is  a 
striking  feature  of  many  cases,  and  often  those  in  which  the  hypertrichosis  is  very  slight,  I 
believe  it  to  be  not  only  the  result  of  the  annoying  growth,  but  a  symptom  of  general  ner- 
vous disease  upon  which  the  hairiness  in  all  probability  depends. 

The  tendency  to  the  growth  of  a  beard  in  females,  like  the  congenital  form  of  hypertri- 
chosis, is  often  found  to  be  hereditary.  In  a  large  number  of  cases  I  have  been  surprised  to 
find  upon  inquiry  that  the  patient  resembles  her  father  in  appearance,  and  in  some  cases  has 
apparently  inherited  the  affection  from  a  paternal  grandmother.  The  paternal  resemblance 
in  these  cases  may  be  taken  as  the  rule  to  which  there  are  few  exceptions. 

Treatment.  The  only  cases  of  hypertrichosis  which  the  physician  is  likely  to  be  called 
upon  to  treat  are  those  in  which  the  gro^vth  of  hair  occurs  upon  the  female  face.  The  depil- 
atory pastes  and  powders  which  have  been  long  in  use  have  little  if  any  more  effect  than  the 
application  of  the  razor.  Neither  will  permanently  eradicate  the  growth.  The  injection  of 
acid,  introduction  of  hot  needles  and  similar  procedures  wiU  often  destroy  the  hairs,  but  not 
without  leaving  scars  which  are  even  more  disfiguring.  The  use  of  electrolysis  in  the  man- 
ner first  suggested  by  Hardaway,  is  the  best  and  the  only  method  by  which  hair  can  be 
permanently  removed  without  injury  to  the  skin.  The  operation  has  been  gradually  perfected 
in  this  country  dxiring  the  past  few  years,  and  constitutes  one  of  the  most  brilliant  achieve- 
ments of  dermatology. 

In  the  destruction  of  the  hairs  by  electrolysis  a  sixteen  or  twenty  cell  battery  is  neces- 
sary, with  a  fine  needle  attached  to  the  negative  cord.  This  is  inserted  carefully  into  the 
follicle  by  the  side  of  the  hair,  and  the  circuit  completed  by  having  the  patient  grasp  a  moist 
sponge  or  electrode  attached  to  the  positive  cord.  Electrolytic  action  now  takes  place  and 
destroys  the  tissue  which  produces  the  hair.  A  stinging  sensation  is  experienced  by  the 
patient,  the  hair  becomes  loosened  in  the  course  of  from  ten  to  thirty  seconds  and  may  be 
removed  by  the  gentlest  traction  of  a  pair  of  forceps. 

ONYCHAUXIS. 
Bj/noni/m — Hypertrophy  of  the  naU. 

An  increased  growth  of  nail  substance  may  produce  a  uniform  thickening  of  the  nail  or, 
as  is  more  frequently  the  case,  a  number  of  ridges,  lumps  and  other  surface  irregularities. 
This  condition  is  most  frequently  observed  in  the  smaller  toe  nails,  which,  instead  of  pre 
senting  the  appearace  of  smooth,  slightly  curving,  homy  patches,  become  roughened,  thick- 
ened and  distorted.    These  deformed  nails,  when  allowed  to  grow,  usually  form  spiral  or 

(138) 


ONTCHA  axis. 

conical  masses,  witli  numerous  transverse  ridges.  The  finger  nails  are  rarely,  if  ever,  affected 
in  a  similar  manner.  When  a  normal  finger  nail  is  allowed  to  grow  without  being  cut  it 
evinces  a  marked  tendency  to  twist  and  roU  when  it  has  attained  the  length  of  a  few  inches, 
but  this  condition  is  not  included  under  hypertrophy  of  the  nail. 

An  abnormal  thickening  of  the  nail  substance  is  commonly  the  result  of  a  diseased  ma- 
trix. A  constant  irritation  resulting  from  pressure  or  chronic  inflammation  increases  the 
functional  activity  of  this  portion  of  the  skin.  With  the  subsidence  of  the  irritation,  a 
healthy  nail  substance  may  again  be  formed,  but  in  all  cases  where  the  matrix  has  been 
injured  beyond  hope  of  restoration  to  a  normal  condition  the  deformed  nail  wiU  always  con- 
tinue to  grow. 

A  peculiar  form  of  affection  resulting  from  h3rpertrophy  of  the  bed  of  the  naU  is  some- 
times called  onychogryphosis.  The  normally  thin  layer  of  epidermis  immediately  beneath 
the  nail  substance  increases  in  thickness  until  it  forms  a  dry  mass  which  raises  up  the  nail 
from  the  bed. 

Treatment.  The  thickened  and  roughened  nail  can  be  somewhat  improved  in  appear- 
ance by  the  application  of  glacial  acetic  acid  and  repeated  scraping,  but  radical  treatment 
must  be  adapted  to  the  condition  of  the  matrix.  Strapping  the  nail  with  adhesive  strips  or 
enveloping  it  in  a  tightly-fitting  elastic  cot  has  been  successfully  tried.  The  accumulation  of 
homy  epidermis  beneath  the  nail  can  be  softened  by  means  of  a  wooden  tooth-pick  dipped 
in  a  strong  potash  solution,  and  dug  out  with  a  fine-bladed  penknife.  A  one  per  cent,  solu- 
tion of  corrosiTe  sublimate  should  then  be  frequently  applied  beneath  the  nalL

CHAPTER  Y. 

ATROPHIC  DISEASES. 

The  class  of  atrophic  affections  includes  those  in  which  one  or  more  of  the  elements  of 
the  skin  are  absent,  diminished,  or  the  seat  of  a  degenerate  process.  As  in  the  preceding 
class,  some  of  the  affections  involve  the  skin  proper,  some  lead  to  an  anomalous  pigmenta- 
tion, while  others  are  characterized  by  an  impaired  nutrition  of  the  hair  and  naUs. 


ALBINISMUS. 

A  congenital  absence  of  pigment  in  the  skin  is  termed  albinismus.  This  may  be  com- 
plete or  partial.  Among  the  lower  animals  the  condition  is  so  common  as  not  to  excite 
attention.  The  white  rabbits,  white  mice  and  white  birds  of  this  climate  are  all  instances  of 
albinism,  and  in  the  polar  regions  an  absence  of  pigment  is  the  rule  rather  than  the  excep- 
tion. This  being  the  case  it  seems  strange  that  in  the  human  race  albinism  should  occur 
with  perhaps  the  greatest  frequence  in  regions  near  the  equator.  The  term  "  albino"  was  first 
applied  by  Portuguese  sailors  to  the  white  negroes  seen  upon  the  coast  of  Africa,  and  it  is 
claimed  that  absence  of  pigment  is  not  very  uncommon  among  this  race  upon  their  own  con- 
tinent. 

An  albino  of  the  Caucasian  race  has  a  milk-white  but  otherwise  normal  skin,  a  growth 
of  white,  fine  silky  hair  upon  the  head,  and  an  absence  of  pigment  in  the  choroid  coat  of  the 
eye,  which  gives  the  iris  and  pupil  a  red  appearance,  such  as  is  often  noted  in  a  white  rabbit. 
In  other  respects  the  physical  condition  of  an  albino  is  normal,  and  the  assertion  that  men- 
tal weakness  is  associated  with  the  general  loss  of  pigment  fails  to  be  verified  in  a  large 
proportion  of  cases. 

Partial  albinism  is  frequently  seen  in  this  country  among  the  southern  negroes,  and 
some  present  the  appearance  of  a  piebald  circus-horse.  The  white  spot  or  spots  remain 
through  life  without  change  of  size  or  tint.  The  affection  is  rarely  if  ever  met  with  in  the 
white  race.

LEUCODERMA. 


LEUOODERMA. 

Synonym —  Vitiligo. 

Leucoderma  is  an  acquired  loss  of  pigment,  occurring  in  spots  or  patches  on  various  por- 
tions of  the  body.  It  is  a  rare  affection,  occurring  generally  in  the  middle  period  of  life, 
and  often  in  persons  who  are  seemingly  in  good  health.  The  spots  of  leucoderma,  unlike  the 
white  piebald  skin  of  partial  albinismus,  tend  to  a  gradual  increase  in  size,  although  in  many 
cases  they  remain  stationary  for  years,  and  sometimes  there  is  noted  a  spontaneous  return  of 
pigmentation.  The  spots  are  always  round  at  the  beginning,  become  oval  as  they  increase  in 
size,  until,  coalescing,  they  form  large  and  irregular  patches,  of  a  milk-white  color,  or  slightly 
roseate  hue  where  there  is  an  active  circulation  of  blood  iu  the  part.  The  skin  adjacent 
to  the  leucodermatous  patch  is  usually  somewhat  darker  than  noi-mal,  thereby  renderino-  the 
affection  more  striking  in  appearance  by  contrast.  This  increased  pigmentation  is  most 
marked  in  a  narrow  zone,  just  beyond  the  advancing  edge  of  the  white  patch,  which  it  sharply 
defines.  It  shades  gradually  off  as  it  recedes  from  the  patch,  and  at  the  distance  of  an  inch 
or  less  the  skin  presents  its  normal  hue. 

The  affection  consists  in  an  abnormal  distribution  of  pigment,  that  which  is  taken  from 
the  affected  patch  being  apparently  deposited  in  the  immediate  vicinity.  At  the  outset  there 
are  usually  a  number  of  smaU  isolated  spots,  which  naturaUy  become  fewer  as  they  increase 
in  size  and  coalesce.  The  favorite  starting-point  of  leucoderma  seems  to  be  the  face,  neck 
and  hands.  From  these  parts  the  affection  may  spread  indefinitely,  and  eventually  affect 
the  greater  portion  of  the  body.  Hebra  mentions  a  case  of  long  standing,  in  which  the 
white  patches  had  coalesced  and  covered  nearly  the  whole  body,  the  normal  pigment  remain- 
ing only  in  smaU  broken  patches  upon  the  backs  of  the  hands  and  feet,  the  elbows  and  the 
face.  Dr.  T.  F.  Wood  reports  an  interesting  case  in  a  colored  woman.  She  was  originally 
quite  black  and  of  pure  negro  parentage.  The  white  spots  first  appeared  on  the  backs  of  the 
hands  and  next  upon  the  body,  presenting  an  almost  exact  symmetry.  The  original  color  of 
the  skin  gradually  disappeared,  and  after  twenty-six  years  the  entire  body  was  free  from  pio-. 
raent  except  the  nipples,  and  there  remained  a  few  black  patches  on  the  face.  Wood  reports 
another  case  in  which  the  pigment  was  in  great  measure  restored  after  leucoderma  had  existed 
a  few  years. 

Since  the  affection  is  simply  due  to  an  absence  of  pigment  in  the  cells  of  the  rete,  it  fol- 
lows that  the  patch  is  neither  elevated  nor  sunken,  neither  thicker  nor  thinner,  neither  harder 
nor  softer  than  the  normal  skin.  In  some  cases  the  leucodermatous  patches  appear  to  be 
unusually  susceptible  to  the  action  of  the  sun  and  other  external  irritants.  There  is  never 
any  desquamation,  and  to  the  touch  alone,  this,  unlike  the  majority  of  skin  affections,  im- 
parts no  information.  The  patient  suffers  no  inconvenience,  or  at  least  experiences  none  of 
the  subjective  sensations  of  cutaneous  disease,  such  as  pain,  hypersethesia,  anaesthesia  or 

(141) 


DISEASES  OF  THE  SKIN— ATROPHIC. 

praritas,  and  the  affection  has  no  influence  upon  Ms  general  condition.  When  hairs  exist  upon 
the  patches  theii'  growth  is  unimpaired,  although  they  are  usually  lighter  in  color,  if  not  quite 
devoid  of  pigment.     The  affection  sometimes  affects  the  scalp. 

It  is  sometimes  difficult,  in  glancing  at  a  case  of  leucoderma,  when  the  loss  of  pigment  is 
extensive,  to  say  at  once  which  is  the  normal  skin — the  dark  or  the  light  patches.  A  fact  to 
bear  in  mind  is  this.  The  advancing  margin  of  a  leucodermatous  patch  is  always  rounded  or 
convex,  and  the  edge  of  the  normal  skin  is  of  necessity  concave.  Accordingly,  if  in  a  given 
case  where  doubt  at  first  glance  might  exist,  it  is  noticed  that  the  whiter  skin  has  a  convex 
or  scoUoped  margin,  it  is  evident  that  we  have  either  a  patch  of  leucoderma  or  partial  albi- 
nismus,  i.  e.,  an  affection  characterized  by  loss  of  pigment ;  while,  on  the  other  hand,  should 
the  whiter  portions  of  skin  be  found  to  have  a  concave  border,  or  to  be  indented,  as  it  were, 
by  the  dark  patches,  it  is  evident  in  that  case,  that  the  white  parts  are  the  normal  skin,  and 
that  we  have  a  case  of  chloasma  or  pigmentary  naevus  to  deal  with ;  in  other  words,  an 
affection  characterized  not  by  loss,  but  by  increase  of  pigment.  At  the  outset  the  round 
spots  of  leucoderma  can  be  readily  recognized  as  such,  but  when  the  skin  is  affected  to  such 
a  degree  that  neither  the  normal  nor  the  affected  skin  is  greatly  in  excess  of  the  other,  the 
diagnosis  may  be  difficult.  It  is  simplified,  however,  when  we  bear  in  mind  the  peculiarity 
of  the  development  of  the  affection,  viz.  :  its  always  presenting  a  convex  or  scoUoped  mar- 
gin. From  partial  albinismus,  which  in  the  negro  race  it  very  much  resembles,  it  can  be 
distinguished  by  the  fact  of  its  not  being  congenital,  but  developing  in  adult  life,  and  from 
the  additional  feature  of  its  not  being  stationary,  but  usually  tending  to  indefinite  extension. 
In  leprosy,  cii'cular  white  patches  are  met  vdih  which  resemble  leucoderma.  They  do  not 
result  simply  from  absence  of  pigment,  however,  and  can  be  distinguished  by  the  atrophic 
changes  and  loss  of  sensibility. 

Treatment.  Of  the  treatment  of  leucoderma  not  much  that  is  enco~iraging  can  be  said. 
By  some  it  is  pronounced  iacurable,  and  there  is  difference  of  opinion  among  \vi-iters  as  to 
the  spontaneous  return  of  pigment  to  leucodermatous  patches.  Arsenic,  iron,  phosphorus, 
cod-Uver  oU,  and  other  remedies  likely  to  exert  an  influence  upon  the  nutrition  of  the  skin 
may  be  tried,  with  the  conviction  that  they  will  act  as  well,  if  not  better,  than  anything  else 
that  might  be  given  internally.  Locally,  an  attempt  may  be  made  to  lessen  the  pigmenta- 
tion surrounding  the  light  patches  by  painting  the  dark  border  with  strong  acetic  acid,  or  a 
one  per  cent,  solution  of  corrosive  sublimate,  or  by  blistering  it  lightly.  This  will  not  tend 
to  cure  the  actual  disease,  but  may  lessen  the  unpleasant  contrast  existing  between  the  white 
patch  and  the  surrounding  skin,  and  thus  render  the  affection  less  striking  in  appearance. 
The  same  result  might  possibly  be  attained  by  applying  mustard  or  other  irritants  to  the 
white  patches,  in  the  faint  hope  of  inducing  inflammation,  and  a  subsequent  pigmentation, 
such  aa  is  so  often  seen  after  eczema  and  other  chronic  skin  affections.

ALOPECIA. 


CANITIES. 


Canities  is  a  term  applied  to  a  loss  of  color  of  tlie  hair,  and  is  the  capillary  analogue  of 
leucoderma.  The  greyness  or  whitening  of  the  hair  may  be  congenital  as  in  all  cases  of  albi- 
nismus  where  it  is  associated  with  absence  of  pigment  elsewhere,  or  it  may  occur  gradually, 
as  it  is  very  apt  to  in  old  age.  In  these  cases  the  canities  is  general,  or  at  least  tends  to 
become  so.  There  are  many  cases,  however,  in  which  the  loss  of  pigment  of  the  hair  is  par- 
tial and  limited  to  one  or  more  circumscribed  patches.  This  may  be  congenital  or  develop 
in  youth  or  middle  age.  A  patch  upon  the  head  is  usually  circular  and  shows  little  or  no 
disposition  to  increase  in  size.  In  some  cases  a  portion  of  the  eyebrow,  moustache  or  beard 
is  affected,  and  as  the  loss  of  pigment  is  frequently  unilateral,  a  singular  contrast  of  the  two 
sides  of  the  face  may  be  presented. 

A  hair  dye  is  the  only  remedy  for  canities,  and  it  is  a  question  in  most  cases  whether  the 
remedy  is  not  worse  than  the  disease. 


ALOPECIA. 

Alopecia  or  loss  of  hair  may  be  complete  or  partial.  In  rare  instances  infants  are  borL. 
without  hair  and  remain  in  this  condition  throughout  life.  It  is  possible,  however,  for  com- 
plete congenital  alopecia  to  give  place  to  a  growth  of  hair  as  the  child  grows  older.  "With 
this  failure  of  hair-growth  there  is  almost  invariably  a  defective  development  of  the  teeth. 
Partial  alopecia  is  far  more  common  than  the  complete  form  and  is  usually  acquired.  It  is  a 
very  frequent  accompaniment  of  old  age  (alopecia  senilis)  and  occtirs  both  as  a  general  thin- 
ning of  the  hair  of  the  head  and  as  a  bald  patch  or  tonsure  on  the  vertex  which  often  extends 
forward  over  the  crown.  The  loss  of  hair  takes  place  gradually,  without  any  notable  change 
in  the  condition  of  the  scalp  and  is  irremediable. 

In  young  persons  loss  of  hair  (alopecia  prematura)  occurs  from  various  causes.  Fevers 
and  prolonged  and  severe  illness  of  any  kind  are  very  apt  to  be  followed  by  a  temporary 
alopecia,  which  usually  disappears  in  a  short  time  after  the  restoration  of  health. 

Syphilis  is  extremely  apt  to  occasion  a  thinning  of  the  hair  in  the  early  stage  of  the  dis- 
ease, and  when  a  secondary  eruption  has  involved  the  scalp  as  well  as  the  body,  the  baldness 
is  frequently  of  a  peculiar  patchy  character.  The  hair  loses  its  lustre  and  grows  thin  in  spots 
which  give  the  scalp  the  appearance  of  having  been  partially  plucked.  This  form  of  alopecia 
affects  the  whole  scalp  and  often  the  eyebrows  and  lashes.  Absolute  baldness  is  rarely  seen, 
and  there  is  usually  a  tendency  to  a  spotaneous  restoration  of  the  hair. 

In  late  syphilis  alopecia  is  extremely  rare  except  as  it  is  directly  produced  by  a  tuber 
cular  or  ulcerative  lesion  of  the  scalp.  Many  writers  on  syphilis  give  a  perfect  descriptioi  i 
of  aloi)ecia  areata  as  occurring  in  the  late  stages  of  syphilis.    This  affection  may  undoubted!  j

DISEASES  OF  THE  SKJX—A  moPUlC. 

occur  in  syphilitic  subjects,  but  its  dependence  upon  syphilis  is  not  at  all  probable  in  any 
ca^^o 

Premature  alopecia  is  commonly  associated  with  some  abnormal  condition  of  the  scalp. 
It  i'j  frequently  observed  to  occur  after  seborrhcEa  or  pityriasis  has  existed  for  several  years, 
but  in  some  cases  the  hair  grows  steadily  finer  and  thinner  without  there  being  any  tendency 
to  dandruff.  This  appears  to  support  the  view  that  the  alopecia  results  from  a  failure  in  the 
process  of  cornification  and  not,  as  many  believe,  from  the  accumulation  of  epidermis  in  the 
hair  follicles  and  a  consequent  atrophy  of  the  hair. 

In  many  cases  of  premature  alopecia,  and  especially  when  the  affection  is  inherited  from 
father  and  grandfather,  it  will  be  found  that  the  scalp  is  drawn  so  tightly  over  the  crown  of 
the  head  that  atrophy  of  the  hair  bulbs  must  inevitably  result.  To  a  certain  extent  this 
accounts  for  the  usual  development  of  alopecia  upon  the  top  of  the  head.  Ordinary  bald- 
ness never  occurs  upon  the  temporal  or  occipital  region  where  there  is  a  muscular  cushion 
beneath  the  scalp,  but  on  the  other  hand,  it  occurs  only  when  the  hair  bulbs  rest  upon  a  hard 
bed,  sueh  as  the  aponeurosis  of  the  occipito-frontal  muscle.  This  also  accounts  for  the 
absence  of  baldness  among  women,  who  are  naturally  endowed  with  a  more  plentiful  supply 
of  adipose  tissue  beneath  the  skin,  and  which  in  case  of  the  scalp,  serves  as  a  soft  cushion  or 
bed  for  the  hair  bulb  and  thus  exempts  them  from  atrophy.  The  singular  predisposition  of 
men  to  baldness  has  been  attributed  to  the  constant  wearing  of  stiff  hats  and  the  consequent 
interference  with  the  blood  supply  of  the  scalp.  But,  taken  in  connection  with  observed 
facts,  neither  this  nor  any  other  explanation  thus  far  given  will  satisfactorily  account  for 
the  thinning  of  the  hair  upon  the  vertex  which  so  frequently  makes  its  appearance  about 
the  age  of  thirty  or  forty. 

Treatment.  For  the  falling  of  the  hair  that  so  frequently  occurs  after  fevers  an  ex- 
pectant plan  of  treatment  will  usually  suffice.  The  patient,  however,  is  often  anxious  to  do 
something,  and  in  addition  to  a  general  roborant  treatment,  the  following  lotion  may  be  pre- 
scribed as  a  capUlary  stimulant :

The  practice  of  shaving  the  head,  recommended  by  so  many  hair  dressers,  and  particu- 
larly those  who  deal  in  wigs,  is  seldom  if  ever  of  any  value.  After  shaving  the  scalp  the 
growth  of  the  hair  is  far  more  noticeable  and  hence  gratifying  to  the  patient,  but  as  the  new 
hair,  after  convalescence  from  fever,  will  come  in  just  as  readily  without  resorting  to  this 
extreme  measure,  there  is  no  occasion  for  the  use  of  the  razor.  In  some  cases,  moreover,  the 
hair  of  young  women  will  never  grow  so  long  as  before,  if  the  razor  is  used. 

The  alopecia  of  early  syphilis  always  tends  towards  a  spontaneous  cure,  but  the  return  of 
the  hair  may  be  hastened  by  the  daily  inunction  of  the  oleate  of  mercury  of  five  per  cent, 
strength.     This  wiU  also  have  a  beneficial  effect  upon  the  papulo-pustular  lesions  which  ai-e

frequently  scattered  over  the  scalp  when  the  eruption  is  copious  iipon  the  body.  Baldness, 
resulting  from  tubercular  or  ulcerative  lesions  of  the  scalp,  is  apt  to  be  permanent,  as  the  hair 
bulbs  are  usually  destroyed. 

When  alopecia  is  associated  with  dandruff  or  any  inflammatory  condition  of  the  scalp, 
much  benefit  may  be  expected  from  judicious  treatment.  The  falling  of  the  hair  can  be 
arrested  even  if  the  lost  hair  cannot  be  restored.  The  treatment  of  the  diseased  scalp  ha? 
already  been  mentioned  in  connection  with  seborrhoea,  pityriasis  and  eczema  capitis,  but  fre- 
quently a  falling  of  the  hair  is  observed  where  there  is  no  dandruff.  In  such  cases  a  great 
deal  can  be  done  by  improving  the  patient's  general  health,  and  stimulating  the  scalp  to  a 
healthier  action.  Anxiety,  severe  mental  excitement,  late  hours  and  dissipation  of  various 
kinds  is  a  prolific  source  of  alopecia,  and  if  the  patient's  nervous  energy  is  constantly  exhausted 
through  such  causes  the  nutrition  of  the  hair  becomes  inevitably  impaired  and  the  resulting 
baldness  is  beyond  the  reach  of  any  "tonic  "  or  " restorative."  When,  as  is  frequently  the 
case,  the  hair  is  abnormally  dry  and  the  scalp  white  and  pasty  in  appearance,  the  daily 
inunction  of  a  very  little  oil,  with  frequent  shampooing,  will  produce  a  speedy  and  beneficial 
effect. 

ALOPECIA  AREATA. 

Synonym — Porrigo  Decalvani. 

Alopecia  areata  is  a  form  of  baldness  which  begins  suddenly  at  one  or  more  points  and 
rapidly  produces  smooth,  white  patches  of  circular  shape  and  variable  size.  These  tend  to 
increase  peripherally  to  a  greater  or  less  extent,  and  often  run  together  in  such  a  manner  as 
to  form  large  irregular  patches,  or  long  streaks  of  baldness.  The  disease  not  only  attacks 
the  scalp  and  beard,  but  also  the  pubes  and  axillae,  and  in  rare  instances  not  a  single  hair 
remains  upon  any  portion  of  the  body.  It  has  no  relation  whatever  to  ordinary  baldness 
occurs  very  frequently  in  young  persons,  and  may  attack  those  who  have  naturally  a  luxuri- 
ant growth  of  hair.  It  is  unaccompanied  by  itching  or  other  subjective  sensations.  After  a 
variable  length  of  time  a  new  growth  of  fine  downy  hair  appears  upon  the  bald  spots.  This 
new  gro^vth  is  frequently  white  at  first,  but  gradually  becomes  pigmented,  and  in  time  no 
trace  of  the  affection  is  to  be  seen.  When  the  bald  spots  are  numerous  some  will  be  found 
to  recover  far  more  quickly  than  others,  and  in  some  cases,  when  the  hair  is  apparently 
growing  normally  once  more,  a  relapse  may  suddenly  occur. 

Concerning  the  etiology  of  the  disease,  very  little  can  be  positively  asserted.  It  appears 
to  be  dependent  upon  a  trophoneurosis  or  functional  nerve  derangement.  A  parasitic  origin 
has  been  claimed  for  it,  but  the  claim  is  by  no  means  established.  Two  or  more  cases  fre- 
quently occur  in  a  family,  and  seem  to  indicate  an  hereditary  tendency  or  predisposition. 

Diagnosis.  The  diagnosis  of  the  affection  is  easy.  Trichophytosis  of  the  scalp  may 
bear  a  resemblance,  but  in  the  latter  affection  the  hairs  break  off  instead  of  falling  out,  and 
leave  rough,  scaly  patches,  quite  different  from  the  smooth,  velvety  areas  of  the  former. 
The  two  affections,  however,  may  co-exist  in  some  cases. 

(145) 


DISEASES  OF  THE  SKIN— ATROF RIO. 


Treatment.  The  treatment  of  alopecia  areata  is,  to  a  certain  extent,  empirical,  and  the 
results  obtained  are  exceedingly  variable.  In  some  cases  there  is  a  tendency  to  spontaneous 
recovery,  and  hair  may  grow  again  upon  the  bald  spots  in  the  course  of  a  few  months,  even 
without  treatment.  Indeed,  nearly  every  case  wiU  get  well  in  time,  but  it  often  requires  a 
lonf  time,  one  or  two  years,  perhaps,  and  though,  in  many  cases  which  recover  spontane- 
ously, the  credit  is  unjustly  awarded  to  the  remedies  employed,  it  is,  nevertheless,  certain 
that  judicious  treatment  tends  to  hasten  a  cure.  In  every  case  a  guarded  prognosis  should 
be  given  as  to  the  time  required  to  effect  a  cure,  Othervdse  the  result  may  bring  discredit 
to  the  physician  and  disappointment  to  the  patient. 

As  nervous  debility,  headaches,  and  other  ills,  often  precede  and  accompany  the  affec- 
tion, it  is  important  that  these  be  detected  and  appropriately  treated.  If  the  general  condi- 
tion of  the  patient  is  not  what  it  ought  to  be,  attention  should  be  directed  to  this  point 
rather  than  to  the  baldness.  There  is  no  special  internal  remedy  which  can  be  recommended 
above  others,  although  on  theoretical  grounds  the  various  nervine  tonics  would  seem  to  be 
indicated.  The  local  treatment  consists  in  epilation  of  the  loose  hairs  surrounding  the  bald 
patch  ;  in  occasional  blistering  of  the  denuded  scalp  ;  in  frequent  shaving  of  the  new  gro-n1;h 
of  hair,  and  in  the  persistent  use  of  various  strongly  stimulating  remedies.  Blistering  and 
shaving  are  remedies  highly  esteemed  by  some,  but  it  is  a  question  whether  they  are  as  bene- 
ficial as  they  are  disagreeable.  I  have  usually  dispensed  with  them,  and  relied  mainly  on 
the  use  of  local  stimulants,  of  which  a  strong  solution  of  ammonia  is  one  of  the  most  effi- 
cient. If  the  odor  of  the  ammonia  is  objectionable,  a  lotion  of  equal  parts  of  the  tincture 
of  cantharidis  and  bay-rum  may  be  applied  morning  and  night.  A  host  of  other  stimulat- 
ing remedies  have  been  recommended,  but  they  all  act  in  the  same  way.  There  is  no  benefit 
to  be  derived  from  changing  from  one  to  another,  except  as  it  may  amuse  the  patient  or  curb 
his  impatient  desire  for  a  speedy  cure. 

The  following  applications  have  been  recommended  in  this  affection  :

ATEOPHlA.    CUTIS. 


ATROPHIA  PILORUM. 

As  a  result  of  various  wasting  diseases,  such  as  phthisis,  and  as  the  direct  effect  of  cer- 
tain affections  of  the  scalp,  such  as  seborrhoea  and  ringworm,  the  hair  often  becomes  dry, 
thin  and  brittle.  The  growth  is  checked  and  the  ends  of  the  hair  usually  split  into  several 
filaments.  In  rare  cases  a  somewhat  similar  defect  of  nutrition  is  idiopathic.  The  shaft  is 
apt  to  be  flattened,  and  in  a  case  reported  by  Duhring,  there  was  fissure  of  the  bulb  or  por- 
tion of  the  shaft  within  the  f oUicle. 


TRICHOREXIS  NODOSA- 

A  peculiar  condition  of  certaia  hairs  of  the  beard  and  moustache  has  been  described  by 
various  writers  under  the  name  of  trichorexis  nodosa.  As  the  term  implies,  the  affection  is 
characterized  by  the  appearance  of  minute  nodules  or  swellings  scattered  along  the  shaft  of 
the  hair,  at  which  poiuts  fracture  is  very  apt  to  occur.  This  leaves  a  brush-like  condition  of 
the  free  extremity  of  the  hair.  The  affection  is  a  rare  one,  and  Little  cau  be  said  respecting 
its  etiology  and  treatment.  It  does  not  appear  to  be  parasitic  in  character,  and  persistent 
shaving  is  the  only  known  remedy. 

In  a  case  reported  by  Smith  of  Dublin,  the  nodules  were  pigmented,  and  the  fracture  of 
the  hair  occurred  in  the  shaft  between  the  nodules. 

ATROPHIA    CUTIS. 

There  are  two  forms  of  atrophy  to  which  the  skin  is  subject.  There  is  a  diffused  atrophy 
or  thinning  of  the  skin  (atrophia  cutis  propria),  and  a  localized  atrophy  which  appears  in  the 
form  of  lines  (strise  atrophicse),  or  roundish  spots  (maculae  atrophicae).  The  first  form  may 
be  the  result  of  age  (atrophia  senilis),  in  which  case  it  is  general  and  associated  with  wasting 
of  the  muscles.  The  skin,  and  notably  the  corium,  may  become  thinner  than  normal,  the 
epidermis  dry  and  wrinkled,  or  a  process  of  degeneration  may  take  place,  in  which  case  there 
is  more  or  less  structural  alteration,  an  increase  of  fatty  matter  and  pigment  being  found. 
Diffused  atrophy  may  assume  the  condition  which  has  been  described  under  the  head  of 
"glossy  skin."  This  usually  attacks  the  fingers,  the  skin  of  which  becomes,  smooth  red  and 
shiny.  The  hairs  are  shed,  the  nails  become  affected  and  painful  excoriations  and  ulcers 
form.  The  affection  is  a  painful  one  and  is  generally  the  result  of  some  lesion  of  the  nerve 
trunk. 

The  localized  form  of  atrophy  produces  whitish  streaks  or  discs  which  present  a  finely 
wrinkled  and  cicatricial  appearance.  Upon  the  abdomen  of  women  who  have  borne  children 
these  atrophic  lines  are  not  uncommon  and  result  from  the  over-distension  of  the  fibrous 
portion  of  the  skin.     They  are  Ukewise  frequently  observed  upon  the  bi  easts  of  those  who

have  nursed  cMldren,  but  pregnancy  and  lactation  cannot  always  be  cited  as  a  cause  of  these 
strijE,  for  I  have  observed  them  upon  the  breast,  abdomen  and  thighs  of  young  girls  as  well 
as  in  men.  Pre-existent  obesity  may  sometimes  account  for  their  appearance  in  the  male  sex, 
but  often  the  lesions  appear  to  be  idiopathic  in  their  origia.  When  seen  at  an  early  stage 
the  lines  are  often  of  a  pinkish  hue  and  elevated  above  the  level  of  the  skin,  the  white  and 
cicatricial  appearance  being  a  later  development.  In  this  regard  the  affection  bears  a  sti-ong 
resemblance  to  morphoea.  Indeed  there  appears  to  be  an  intimate  pathological  relation  be- 
tween the  two  affections,  and  Duhring  states  that  in  several  cases  he  has  seen  well-marked 
atrophic  lines  and  spots  associated  with  the  more  characteristic  patches  of  morphoea. 
The  affection  gives  rise  to  no  inconvenience  and  is  not  amenable  to  treatment. 

ONYCHATROPHIA. 

In  certain  affections  involving  the  greater  portion  of  the  skin  (notably  lichen  ruber)  a 
thin  and  brittle  condition  of  the  nails  is  frequently  observed.  The  same  condition  often 
appears  without  apparent  cause  and  is  sometimes  hereditary.  The  surface  of  the  nail  loses 
its  lustre,  numerous  ridges  or  splits  running  parallel  with  its  long  axis  appear,  and  the  free 
margin  and  side  of  the  naU  become  broken  and  uneven.  In  some  cases  numerous  dents  or 
pits  are  seen  scattered  over  the  surface. 

Treatmejtt.  When  the  defective  nutrition  of  the  nail  arises  from  a  chronic  inflamma- 
tory condition  of  the  matrix,  whether  the  nail  substance  be  increased  or  lessened  in  amount, 
I  have  seen  a  good  result  foUow  the  repeated  immersion  of  the  end  of  the  finger  in  the  fol- 
lowing pigment.

NEOPLASTIC   DISEASES. 
CICATRIX. 

Synonym —  Scar. 

A  cicatrix  is  a  new  growth  of  connective  tissue  wliich  takes  the  place  of  a  loss  of  sub- 
stance of  the  corium  A  loss  of  epidermis  is  replaced  by  a  normal  cell  growth,  but  when  a 
portion  of  the  corium  or  true  skin  is  destroyed  by  injury  or  disease,  the  formation  of  a  scar  is 
inevitable.  The  margin  of  a  cicatrix  is  well  defined,  and  its  surface  is  either  continuous  with 
the  level  of  the  surrounding  skin  or  raised  or  sunken.  Its  form  is  varied,  being  punctate, 
linear,  discoid  or  reticular,  according  to  the  nature  of  the  preceding  ulceration.  It  is  less 
pliable  than  the  healthy  skin  and  is  devoid  of  hair  and  glands.  Its  color  is  at  first  light  red, 
but  after  a  lajjse  of  time  which  varies  in  different  individuals  it  becomes  colorless  or  remains 
more  or  less  pigmented.  It  may  be  movable  over  the  underlying  tissue,  or  bound  down  to 
the  fascia  or  periosteum  beneath. 

The  skin  diseases  which  are  superficial  in  their  character,  such  as  eczema,  psoriasis  and 
pemphigus,  do  not  as  a  rule  leave  scars,  although  these  may  occasionally  be  produced  by 
severe  friction  of  the  clothing,  vigorous  scratching,  or  by  any  cause  sufficient  to  injui-e  the 
corium.  In  certain  vesicular  or  pustular  affections  which  are  more  deeply  seated,  such  as 
zoster,  acne  and  fiiruncle,  scars  are  frequently  left,  whUe  in  lupus,  leprosy  and  ulcerative 
syphilis  they  invariably  result  from  the  loss  of  cutaneous  substance, 

A  cicatrix  is  composed  of  dense  fibrous  tissue,  containing  vessels,  and  is  covered  by  a 
thin  layer  of  epidermis.  A  tendency  to  contraction  is  usually  a  marked  feature  of  the 
growth,  and  when  the  loss  of  substance  has  been  considerable  and  has  involved  a  lax,  movable 
tissue,  more  or  less  deformity  is  apt  to  be  produced  by  the  cicatricial  formation.  In  some 
cases  the  motion  of  a  joint  is  seriously  impaired,  the  eyelids  are  everted,  or  the  head  drawn 
to  one  side,  while  in  others  an  artificial  web  is  formed  between  the  fingers  or  between  the  ear 
and  scalp. 

Cicatricial  tissue  may  be  the  seat  of  eruptions  which  affect  the  surrounding  skin,  e.  g., 
psoriasis,  and  is  especially  liable  to  become  the  seat  of  keloid.  Neuralgic  pain  in  scars  some- 
times results  from  the  imprisonment  of  terminal  nerve  fibres  in  the  dense  tissue. 

Treatment,  The  character  of  a  cicatrix  depends  largely  upon  the  treatment  of  the 
wound  or  ulcer  which  precedes  it,  and  judicious  surgical  measures  Avill  often  cause  a  smooth 
scar  to  form  in  place   of   the  puckered    or  lumpy  condition  which  would  naturally   re- 

(149) 


DISEASES  OF  THE  SKlIf.— NEOPLASTIC 

siUt.  Much  care  should  always  be  exercised  in  the  coaptation  of  cut  or  torn  portions  of 
skin,  and  the  prominent  masses  which  are  sometimes  seen  in  large  ulcers  should  be  leveled  by 
the  use  of  nitrate  of  silver  or  the  actual  cautery  before  complete  cicatrization  ensues.  A  scar 
once  formed  can  never  be  entirely  removed,  but  a  plastic  operation  will  often  improve  its 
appearance  and  lessen  its  objectionable  features. 

The  deformity  resulting  from  the  contraction  of  a  large  ulcerated  surface,  which  is  espe- 
cially apt  to  disfigure  the  face  or  impair  the  motion  of  joints,  can  be  remedied  to  a  certain 
extent  by  the  operation  known  as  skin-grafting. 

KELOID. 

Keloid  is  a  cutaneous  tumor  which  usually  develops  upon  the  site  of  a  cicatrix.  It  results 
from  a  new  growth  of  connective  tissue,  and  may  affect  various  portions  of  the  body.  It  is 
variable  in  size,  and  thongh  usually  small,  it  may  in  rare  cases  assume  immense  proportions. 
It  is  generally  a  single  growth,  but  may  occur  in  the  form  of  multiple  tumors,  especially  when 
it  arises  from  cicatrices.  Its  shape  is  usually  oval  or  irregular,  and  more  or  less  flattened,  and 
one  or  more  straight  or  bifurcated  processes  are  seen  projecting  in  every  typical  case.  These 
have  given  origin  to  the  name  keloid  (like  the  claw  of  a  crab).  In  some  instances  the  growth 
rises  abruptly  from  the  surrounding  healthy  skin  and  forms  a  plump  convex  tumor,  while 
in  other  cases  it  is  reticulated  in  appearance,  from  the  interlacing  of  cicatricial  ridges.  The 
margins  of  the  growth  are  sometimes  elevated  and  inclose  a  central  depressed  area.  Its  sur- 
face is  smooth,  of  a  whitish  or  duU  pinkish  hue,  and  is  frequently  streaked  with  a  fine  net- 
work of  small  dilated  vessels.  The  grovrth  is  firm  and  elastic  to  the  touch,  usually  tender 
when  pressed  upon  or  squeezed,  and  in  some  instances  gives  rise  to  severe  intermittent 
pain  even  when  carefully  p'-otected.  The  processes  radiating  from  the  gro^vth  tend  to 
contract  and  produce  a  puckered  condition,  such  as  surrounds  the  cicatrix  of  an  extensive 
burn.  A  favorable  site  of  keloid  is  the  sternal  region,  where  it  appears  as  an  elongated  flat- 
tened tumor  crossing  the  median  line  in  a  transverse  direction.  It  occurs  frequently  upon 
the  back  and  sides  and  also  upon  the  scalp  and  face.  It  is  slow  in  its  development,  and  is 
never  associated  with  any  constitutional  symptoms.  It  neither  ulcerates  nor  tends  as  a  rule 
to  spontaneous  disappearance,  but  after  reaching  a  certain  size  remains  in  the  same  condition 
for  many  years. 

One  of  the  most  remarkable  cases  of  keloid  which  I  have  seen  was  in  the  Philadelphia 
Hospital,  under  the  care  of  Dr.  Maury,  who  gave  the  following  history  of  the  case,  together 
with  an  illustration  in  the  Photographic  Review  (Oct.  1878).  The  patient,  a  colored  man, 
(formerly  a  slave),  aged  twenty-eight  years,  was  above  the  ordinary  height,  of  large  frame 
and  very  muscular.  His  family  history  revealed  nothing  from  which  to  trace  the  cause  of 
his  disease.  Wlien  eight  years  of  age,  a  small  abscess  made  its  appearance  on  the  anterior 
part  of  the  neck,  which,  on  being  opened,  discharged  an  ounce  of  pus.  As  the  result  of  tlus 
abscess,  a  well-marked  induration  followed  at  the  original  seat,  which  gradually  extended  in 

(150) 


KELOID. 

both  directions  around  the  neck.  After  nine  years'  growth  it  had  half  encircled  the  neclc, 
and  was  about  two  inches  in  width.  At  this  time  the  growth  was  removed.  The  wound 
healed  kindly  in  six  weeks,  but  the  line  of  the  cicatrix  was  speedily  occupied  by  a  hard 
rounded  ridge,  which  slowly  extended  and  enlarged. 

Eighteen  months  later  an  accidental  wound  was  inflicted  by  an  axe  on  the  posterior  part 
of  the  neck.  This  wound  also  presented  a  hard,  nodulated  cicatrix,  which  crept  around  the 
neck  to  join  the  one  in  front.  Seven  years  after  the  first  operation  it  was  removed  again,  at 
which  time  it  had  extended  around  the  entire  neck.  Three  months  were  occupied  in  the 
healing  of  the  wound,  which  also  assumed  the  same  morbid  action.  At  date  of  report  there 
were  thirty-seven  tumors  of  variable  size,  one  resembling,  in  a  marked  degree,  the  ruffles 
worn  in  the  time  of  Queen  Elizabeth.  The  two  original  growths  were  thoroughly  blended 
and  formed  one  solid  mass,  touching  at  the  posterior  part  of  the  neck.  It  measui-ed  twenty- 
eight  inches  in  its  greatest  circumference  and  five  inches  in  its  perpendicular  diameter.  It 
was  plicated  and  had  deep  fissures  separating  the  folds,  from  the  bottom  of  which  exuded 
a  thin,  yellowish,  offensive  fluid.  It  was  not  painful,  normally  sensitive,  and  the  entire  mass 
could  be  moved  \\'ithout  difficulty,  thereby  indicating  only  a  cutaneous  attachment. 

The  cause  of  keloid  is  unknown.  Observation  teaches  that  in  the  vast  majority  of  cases 
it  develops  at  some  point  where  cutaneous  injury  has  taken  place.  The  cicatrices  of  acne 
upon  the  back,  of  boils  or  carbuncles  upon  the  nape  of  the  neck,  of  variola  upon  the  face, 
and  of  vaccination  upon  the  ann  are  frequently  observed  to  be  the  site  of  keloidal  growths. 
The  removal  of  lupus  by  scraping  has  been  followed  in  many  cases  by  keloidal  cicatrices, 
especially  in  strumous  subjects.  Purdon  reports  a  case  of  keloid  following  psoriasis,  and 
Taylor  a  case  in  which  numerous  keloidal  growths  developed  upon  the  site  of  syphilitic  ulcers, 
and  occasioned  ten-ible  itching  at  night.  Negroes  appear  to  be  more  frequently  affected  by 
keloid  than  white  persons.  Whether  this  is  due  to  a  peculiarity  of  the  race  or  to  the  fact 
that  their  skins  are  more  frequently  pitted  with  variola,  scarred  by  strumous  abscesses,  and 
disfigured  by  the  lash,  may  be  a  question.  The  disease  is  never  hereditary.  A  division  of 
keloid  has  been  made  into  a  spontaneous  and  a  cicatricial  variety,  the  former  embracing 
those  cases  of  idiopathic  origin,  the  latter  comprising  those  which  develop  upon  cicatrices. 
As  it  is  well  known  that  keloidal  tumors  of  considerable  size  and  attended  by  pain  result 
from  the  most  trifling  injury  to  the  skin,  it  seems  quite  probable  that  every  case  of  keloid  is 
of  traumatic  origin,  and  the  so-called  idiopathic  cases  have  been  produced  by  the  prick  of  a 
pin  or  some  other  insignificant  injury  of  which  the  patient  took  little  or  no  notice  at  the  time. 
The  term  spurious  keloid  might  be  advantageously  abandoned  or  applied  to  a  form  of  hyper- 
trophic development  of  cicatricial  tissue  sometimes  met  with,  and  which  differs  from  true 
keloid. 

The  name  keloid,  like  many  other  dermatological  terms,  has  been  diverted  from  its  ori- 
ginal signification  and  applied  to  distinct  affections.  We  hear  accordingly  of  Alibert's  keloid 
and  Addison's  keloid.  Concerning  the  nature  of  the  latter  affection,  or  morphcea,  there  is 
much  doubt  existing  among  dermatologists,  but  one  thing  is  certain,  it  is  not  keloid. 

(161) 


DISEASES  OF  THE  SKIN— NEOPLASTIC. 

Diagnosis.  The  diagnosis  of  the  disease  is  usually  an  easy  matter.  The  firm,  elastic 
tumor,  the  processes  (which  however  are  not  invariably  present),  the  puckering  of  the  sur- 
roundiao-  skin,  the  long  duration  of  the  growth  and  the  unimpaired  health  of  the  patient  are 
characteristic  features  which  will  serve  to  distinguish  it  from  other  affections.  The  diagnosis 
of  genuine  from  spurious  keloid  depends,  according  to  -writers  who  make  the  distinction, 
upon  the  idiopathic  or  traumatic  origin.  The  origin,  as  has  been  remarked,  is  often  uncer- 
tain and  the  distinction  is  unnecessary.  It  must  be  remembered,  however,  that  cicatrices 
often  become  thickened  and  lumpy  through  condensation  of  tissue  and  are  with  difficulty 
distinguished  from  keloid. 

Treatment.  In  the  treatment  of  the  disease  success  seems  to  depend  in  great  measui-e 
upon  idiosyncracy  on  the  part  of  the  patient.  A  method  which  will  succeed  admirably  in 
one  case  will  fail  utterly  in  another,  and  caution  must  be  observed  in  stating  beforehand 
what  the  resiilt  of  treatment  will  be.  Excision  of  the  tumor  or  destruction  by  caustics 
usually  does  more  harm  than  good,  as  the  growth  usually  reappears  even  before  the  wound 
is  healed,  and  soon  reaches  a  greater  size  than  before  the  operation.  This  is  especially  the 
case  when  the  growth  is  progressive.  When  there  has  been  no  increase  in  size  for  several 
years,  caustic  potash  or  glacial  acetic  acid  may  be  cautiously  used.  I  have  seen  a  case  of 
reticulated  keloid  following  variola,  which  was  greatly  improved  by  parallel  incisions  and  the 
use  of  concentrated  acid.  Vidal  reports  two  cases  in  which  scarification  alone  was  productive 
of  benefit.  In  one  case  he  adopted  this  treatment  with  a  view  to  relieve  the  patient  of  pain. 
The  scarifications  were  numerous  and  made  at  right  angles  to  each  other.  After  three  such 
operations  he  was  satisfied  that  a  real  amelioration  had  taken  place,  and  by  a  continuation  of 
the  treatment  succeeded  in  nearly  curing  the  disease.  An  ointment  of  iodide  of  lead  or  of 
iodide  of  potassium  or  elastic  collodion  may  be  applied  with  a  certainty  of  at  least  doing  no 
harm.  Where  excessive  pain  is  present  hypodermic  injections  of  morphia  or  anodyne  lotions 
are  required. 

For  the  treatment  of  keloidal  acne  or  the  hypertrophied  cicatrices  which  often  follow 
the  incision  or  spontaneous  evacuation  of  small,  indolent  abscesses  in  the  cheek,  Bazin 
recommended  frictions  every  second  day  with  the  oil  of  cade,  and  night  and  morning  a  tea- 
apoonf ul  of  the  following  in  barley  water  :

FIBROMA. 

Synonyms — Molluscum  Fibrosum.     Fibroma  Mbllttacum. 

Fibroma  is  a  new  growth  of  connective  tissue  which  may  be  found  in  various  organs  of  the 
b  >dy.     Occurring  in  the  skin  it  forms  one  or  more  tumors  which  often  vary  greatly  in  size 

(152)

FIBROMA. 

aud  appearance.    These  involve  tlie  corium  and  reticulated  subjacent  tissue.     In  all  cases 
they  are  painless  and  benignant  in  character. 

The  most  common  and  simplest  form  of  fibroma  is  apt  to  occur  upon  the  face  in  adult 
life  in  the  form  of  a  pea-sized  hemispherical  nodule  of  firm  consistence.  This  is  most  fre- 
quently seen  upon  the  side  of  the  nose  or  cheek  and  is  often  spoken  of  as  a  "wart"  or 
"mole."     Occasionally  it  is  the  seat  of  a  growth  of  coarse  and  stiff  hairs  (nsevus  pilosus). 

Another  simple  form  of  cutaneous  fibroma  occurs  as  a  small  pouch-like  tumor  or  polypus 
of  the  skin  which  may  be  flattened  or  elongated  and  connected  by  a  pedicle.  This  gro^vth 
is  usually  seen  upon  the  neck,  breast  or  back,  and  is  apt  to  be  more  or  less  pigmented.  The 
sebaceous  ducts  are  sometimes  distended  and  white,  cheesy  threads  can  be  extruded  by  pres- 
sure. Very  small,  thread-like  appendages  are  sometimes  observed  upon  the  neck  of  females 
with  a  coarse  skin,  and  have  been  described  under  the  name  of  Acrochordon. 

In  a  case  of  multiple  fibroma  numerous  soft  and  flaccid  tumors  are  scattered  over  the  sur 
face  of  the  body.  These  vary  in  size  from  a  pea  to  a  walnut,  and  produce  an  affection  of 
striking  appearance,  although  exerting  no  influence  upon  the  health  and  general  condition 
of  the  patient.  They  are  sometimes  congenital,  increasing  gradually  in  size  up  to  a  certain 
limit,  but  are  generally  an  acquired  growth.  In  many  instances  the  affection  appears  to  be 
hereditary  and  affects  two  or  more  members  of  a  family.  Some  of  the  tumors  may  be  of  a 
somewhat  firm  consistence  and  feel  like  a  split  pea  imbedded  in  the  skin,  but  the  majority 
are  pouch-like,  and  pressure  with  the  finger  shows  that  the  corium  at  their  base  is  thinner 
than  elsewhere.     In  color  they  differ  very  little  from  the  surrounding  skin. 

Occasionally  a  fibroma  becomes  large,  pendulous  and  pedunculated.  It  may  occur  alone 
or  in  connection  -ivith  the  smaller  growths  already  described.  The  surface  of  this  pyriform 
tumor  may  be  smooth  and  white,  the  skin  appearing  normal  in  structure,  though  stretched 
by  the  increased  growth  of  fibrous  and  areolar  tissue  beneath.  In  some  cases  the  sebaceous 
glands  upon  the  surface  are  enlarged  and  the  ducts  unusually  prominent.  Its  color  is  usiially 
pale,  although  the  most  dependent  portion  may  present  a  dull  red  hue,  and  in  some  cases 
become  the  seat  of  ulceration.  The  constricted  base  is  usually  of  a  denser  structure  and  the 
pedicle  is  often  connected  with  the  deep  reticulated  layer  of  the  skin. 

In  certain  rare  cases  the  fibrous  growth  hangs  in  one  or  more  folds  of  skin  from  a  broad 
base  and  constitutes  the  affection  which  has  been  termed  Pachydermatocele  or  Dermatolysis. 
This  growth  differs  in  no  essential  respect  from  the  pedunculated  tumor,  although  the  corium 
is  apt  to  be  specially  involved.  It  may  coexist  mth  a  number  of  small  sessile  fibromata  and 
is  identical  in  nature,  though  differing  in  shape  and  appearnce.  The  skin  in  some  cases 
appears  coarse  in  texture  and  is  slightly  pigmented,  while  in  others  it  is  atrophied  from  ten- 
sion and  appears  smooth  and  fine.  The  periphery  of  the  growth  is  generally  more  dense  than 
the  included,  projecting  portion. 

The  cause  of  this  affection  is  unknown.  It  occurs  in  both  sexes  and  in  individuals  whose 
general  condition  is  good.  A  stunted  condition  of  both  mind  and  body  has  been  noted,  how- 
ever, in  certain  cases. 

(163) 


DISEASES  OF  THE  SKIN.— NEOPLASTIC. 

Diagnosis.  Small  fibromata  of  firm  consistence  might  be  mistaken  for  sarcomata,  but 
in  the  latter  case  the  tumors  are  of  a  dull  red  hue  and  tend  to  ulcerate.  Mollusca  are  readily- 
distinguished  by  their  central  aperture  from  which  curd-lilie  contents  may  be  expressed. 

Tr"EATMEnt.  The  treatment  of  fibroma  is  not  imperative,  as  the  affection  usually  occa- 
sions no  discomfort.  In  a  few  cases  spontaneous  involution  of  certain  tumors  has  been 
observed.  When  the  growths  are  small  they  may  be  let  alone,  when  large  and  pedunculated 
they  may  be  removed  by  the  knife,  galvano-caustic  loop,  or  elastic  ligature.  In  the  pendu- 
lous and  especially  the  plicated  form,  the  liability  to  erysipelas  must  be  considered  before 
attempting  an  operation,  but  such  growths  have  been  successfully  removed  by  Mott,  Danzel, 
Bryk,  Pollock  and  others. 


XANTHOMA. 
Synonyms — Xan  thelasma. —  Vitiligoidea, 

Xanthoma  is  an  affection  in  which  one  or  more  circumscribed  patches  or  small  tumors  of 
a  yellowish  color  gradually  develop  in  the  skin.  The  lesions  are  of  a  chronic  character,  and 
are  most  frequently  observed  upon  the  upper  eyelid,  near  the  internal  canthus.  In  this 
locality  xanthoma  usually  appears  as  an  oval  patch  which  is  but  slightly,  if  at  all,  elevated, 
and  presents  the  appearance  of  being  imbedded  in  the  skin.  As  it  frequently  occurs  in  wo- 
men with  a  dark  complexion  and  dark  pigmentation  around  the  eyes,  its  yellowish  hue  con- 
trasts strongly  with  the  adjoining  skin.  One  or  both  lids  may  be  affected,  and  with  the 
exception  of  the  disfigurement,  they  occasion  no  discomfort  to  the  patient.  Upon  other 
poi-tions  of  the  body  xanthoma  is  apt  to  assume  a  tubercular  form,  and  in  some  cases  small, 
rounded  tumors  develop.  Upon  the  palms  and  soles,  and  on  the  flexor  surface  of  the  joints 
the  growth  usually  invades  the  natural  creases  of  the  skin  and  produces  a  number  of  yellow- 
ish or  whitish  lines  or  streaks.  These  varieties  of  the  disease  may  be  designated  as  xantlionia 
planum,  xanthoma  tuberosum,  and  xanthoma  striatum. 

The  cause  of  the  affection  is  often  obscure,  but  most  of  those  who  have  carefully  studied 
a  number  of  cases  are  disposed  to  connect  it  with  hepatic  disease.  In  a  few  cases,  in  which 
the  cutaneous  lesions  appeared  suddenly  and  gradually  disappeared,  diabetes  was  present 

Diagnosis.  The  affection  is  readily  recognized  when  it  occurs  upon  the  eyelids,  and  in 
a  weU-developed  form.  The  only  affection  which  at  aU  resembles  it  is  milium.  In  the  for- 
mer case  the  lesions  are  flat  and  evince  a  tendency  to  coalesce.  In  the  latter  the  lesions  are 
isolated,  elevated  and  easily  removed  from  the  skin  after  a  slight  incision. 

Treatment.  The  best  plan  of  treating  xanthoma  palpebrarum  is  excision.  I  have 
partly  destroyed  the  growth  and  rendered  it  comparatively  inconspicuous  by  the  use  of  f,he 
electrolytic  needle,  and  would  recommend  this  plan  of  treatment  in  cases  where  the  patient 
objects  strongly  to  the  use  of  the  knife.  Xanthomatoua  tubercles  upon  the  body  may  be 
excised  or  left  untreated.

TELANGIECTASIS. 


NEUROMA. 


Neuroma  of  the  skin  is  a  rare  affection  in  wMch  one  or  more  nodules  develop  and  become 
extremely  painful.  The  few  cases  reported  have  occurred  in  men,  and  the  seat  of  the  affec- 
tion has  been  in  the  region  of  the  brachial  or  sacral  plexuses  of  nerves.  In  a  case  reported 
by  Duhring  the  tubercles,  which  were  numerous  upon  the  shoulder  and  arm,  were  of  a  pur- 
plish color  and  slightly  scaly.  The  pain,  which  was  absent  at  first,  became  excruciating 
after  a  few  years,  and  occurred  in  paroxysms  of  about  an  hour's  duration.  Exsection  of  an 
inch  of  the  brachial  plexus  of  nerves  was  followed  by  a  marked  diminution  of  pain,  and  a 
decrease  in  the  size  of  the  nodules. 


TELANGIECTASIS. 

Telangiectasis  is  a  dilatation  of  one  or  more  fine  superficial  blood  vessels,  and  is  usually 
observed  upon  the  face.  It  is  never  a  congenital  affection,  and  usually  develops  in  youth  or 
middle  age.  It  may  exist  alone  or  in  connection  with  other  affections  of  the  skin.  In  rosa- 
cea it  is  generally  a  marked  feature  of  the  disease  and  is  seen  chiefly  upon  the  wings  of  the 
nose.  In  erythematous  lupus  and  morphoea  the  margin  of  the  patches  often  presents  a  fine 
network  of  enlarged  capillaries,  while  in  moUuscum  and  superficial  epithelioma  the  fine  red 
vessels  may  be  seen  running  up  over  the  abrupt  edges  of  the  growth. 

In  telangiectasis  occurring  alone  the  vascular  dilatation  may  be  localized  or  diffused. 
In  the  former  case  it  appears  as  a  bright  red  point  or  blotch,  usually  upon  the  cheek,  and  is 
often  the  result  of  some  slight  injury  to  the  skin  which  may  have  been  long  forgotten  by  the 
patient.  Sometimes  the  dilated  vessels  form  a  minute  and  elevated  tumor,  while  in  other 
cases  thpre  is  no  elevation  whatever,  and  fine  red  lines  radiate  like  the  legs  of  a  spider  from 
the  central  point  or  plexus  of  vessels  (Nsevus  araneus). 

In  the  diffused  form  of  telangiectasis  a  portion  of  skin  will  present  at  a  distance  a  dull 
red  hue  which,  on  close  inspection,  is  found  to  result  from  an  extensive  arborization  of  fine 
superficial  vessels.  This  condition  is  often  noted  on  the  cheeks  of  coachmen  and  others 
whose  faces  are  constantly  exposed  to  the  cold  air  and  wind. 

Telangiectasis  is  never  accompanied  by  any  subjective  sensation,  such  as  pain  or 
itching.  It  usually  develops  slowly  and  remains  for  years  without  undergoing  any  notable 
change.     In  some  cases  it  may  disappear  spontaneously. 

Diagnosis.  A  red  point  or  patch  produced  by  a  dilatation  of  capillary  vessels  might  be 
mistaken  for  an  inflammatory  affection  of  the  skin,  but  the  absence  of  heat,  pain  and  swell- 
ing is  an  important  diagnostic  feature.  Furthermore,  the  chronicity  of  the  red  spot  and 
the  fine  curving  or  tortuous  Lines  apparent  on  close  examination  will  reveal  the  true  nature  of 
the  affection.  Telangiectasis  differs  from  wine-mark  in  not  being  congenital  and  never  form- 
ing an  extensive  and  circumscribed  patch. 

(155) 


DISEASES  OF  THE  SKIN— NEOPLASTIC. 

Treatjiext.  For  the  destruction  of  the  dilated  vessels  in  telangiectasis  several  plans 
have  been  employed  with  success.  Transverse  scarification,  repeated  if  necessary,  will  usu- 
ally effect  their  obliteration,  although  it  is  apt  to  leave  faint  linear  cicatrices.  When  the 
superficial  cai)illai'ies  upon  the  sides  of  the  nose  are  elevated,  as  is  frequently  the  case  in 
rosacea,  the  vessels  may  be  laid  open  with  a  fine  bistoury  and  the  persulphate  of  iron  in 
solution  or  the  nitrate  of  silver  appUed  to  the  fresh  cut.  In  general,  however,  the  dilated 
vessels  can  best  be  destroyed  by  means  of  a  fine  needle  attached  to  the  negative  pole  of  a 
galvanic  battery.  This  should  be  introduced,  if  possible,  at  the  point  where  the  vessel 
emerges  from  the  deeper  layer  of  skin,  although  it  is  often  necessary  to  introduce  the  needle 
at  several  points  along  the  course  of  the  vessel.  This  operation  is  not  pai'ticiilarly  painful 
and  is  always  effective. 

N-S:VUS   VASCULOSUS. 

Synonyms — Angioma  Simplex. —  Wiite-mark. — Fire-mark, 

Nsevus  vasculosus  is  an  affection  in  which  a  dark  red  or  purplish  patch  results  from  a 
dilatation  or  new  growth  of  cutaneous  vessels.  This  is  a  condition  of  the  skin  similar  to  that 
seen  under  normal  circumstances  upon  the  vermillion  border  of  the  lip.  The  affection  is 
always  congenital  or  apparent  shortly  after  birth,  and  in  this  respect  it  differs  from  telangi- 
ectasis. 

A  vascular  nsevus  has  usually  a  smooth  surface,  an  irregular  form  and  a  rather  sharply- 
defined  outline.  In  certain  well-marked  cases  the  smooth  surface  is  broken  here  and  there 
by  the  development  of  smaU  erectUe  tumors  of  the  size  of  a  pin's  head  or  a  small  pea.  In 
the  very  worst  cases  the  livid  patch  may  be  the  seat  of  numerous  soft,  rounded  tumors  of 
variable  size  which  give  to  the  slcin  a  warty  or  molluscous  appearance.  These  are  not  con- 
genital, but  develop  gradually  upon  a  comparatively  smooth  i^atch. 

The  extent  of  surface  involved  in  vascular  nsevus  varies  greatly  in  different  cases.  In 
one  case  a  faint  pinkish  mark  no  larger  than  a  quarter  dollar  may  be  seen  at  the  edge  of 
the  hair  upon  the  occiput  or  neck,  a  site  where  the  mildest  form  of  vascular  njevus  is 
very  common.  In  another  case  a  red  mark  of  a  florid  or  livid  hue  may  cover  one-half  or 
the  greater  portion  of  the  face  and  extend  down  upon  the  neck  and  trunk.  In  one  case  now 
under  my  care  a  succession  of  patches  of  variable  size  extend  from  the  forehead  to  the  foot, 
nearly  one-half  of  the  left  side  of  the  body  being  affected.  The  upper  portion  of  the  body 
and  the  face  in  particular  is  unfortunately  the  favorite  site  of  this  affection.  Although  the 
red  patches  may  occur  upon  both  sides  of  the  face  or  body  they  never  manifest  any  tendency 
to  symmetrical  distribution.  In  the  great  majority  of  cases  the  affection  is  unilateral,  but 
when  bilateral,  one  side  is  always  affected  to  a  much  greater  extent  than  the  other. 

The  color  of  vascular  naevus  varies  from  the  lighest  shade  of  red  to  a  dark  purplish-blue 
or  slate  color.  The  general  tone  of  a  patch  or  a  number  of  patches  in  a  given  case  does  not 
admit  of  great  variation,  although  some  portions  of  the  affected  skin  may  be  slightly  darker 

(156) 


N^VUS   VASCULOSUS, 

than  others.  In  cold  weather  a  vascular  ngevns  usually  appears  darker  or  bluer  than  at  other 
times,  on  account  of  the  diminished  flow  of  fresh  arterial  blood  to  the  part.  On  the  other 
hand,  active  exercise  or  whatever  tends  to  cause  cutaneous  congestion  will  temporarily  in- 
crease the  bright  redness  of  the  patch. 

Treatjient.  Up  to  a  recent  date  the  profession  and  the  laity  have  shared  the  opinion 
that  nothing  could  be  done  for  the  relief  of  patients  aiBicted  with  a  wine-mark.  In  most 
works  on  surgery  no  plan  of  treatment  is  even  suggested  for  this  flat  form  of  nsevus,  and  in 
spite  of  the  zealous  endeavors  of  a  few  dermatologists  to  devise  some  successful  means  of 
removing  this  common  deformity  of  the  skin,  it  must  be  confessed  that  no  proposed  plan  of 
treatment  has  as  yet  met  with  general  favor.  Some  encouraging  results  have  nevertheless 
been  attained,  and  it  may  be  confidently  asserted  that  all  cases  of  wine-mark,  and  especially 
the  worst  cases,  can  be  improved  by  treatment. 

To  remove  a  wine- mark  by  deep  cauterization  is  a  simple  matter,  but  the  dead  white 
cicatrix  which  would  result  from  such  a  procedure  would  generally  be  regarded  as  quite  as 
unsightly  as  the  red  patch.  The  object  of  every  plan  of  treatment  should  be  the  destruction 
of  the  blood-vessels  with  the  minimum  amount  of  injury  to  the  skin. 

A  vascular  nsevus  of  superfcial  character  and  light  color  is  best  treated  by  mild  cauteri- 
zation of  the  patch,  repeated  at  intervals  until  a  beneficial  effect  is  produced.  This  requires 
time  and  patience  on  the  part  of  both  physician  and  patient.  The  application  which  is  least 
apt  to  injure  the  skin  and  still  capable  of  lessening  the  redness  in  some  degree  is  carbolic 
acid.  This  may  be  applied  pure  to  a  portion  of  the  patch  and  re-applied  in  a  week  or  ten 
days,  when  the  outer  layer  of  skin  has  peeled  off  and  left  a  smooth  surface.  It  is  advisable 
to  apply  the  acid  in  the  form  of  a  broad  stripe  running  across  the  patch  in  such  a  manner 
that  the  effect  of  treatment  may  be  noted  by  the  subsequent  contrast  between  the  stripe  and 
the  untreated  portions  of  the  nsevus.  If  the  acid  be  applied  to  a  considerable  portion  of  skin 
some  susceptible  patients  wUl  complain  of  dizziness  or  perhaps  evince  marked  symptoms  of 
intoxication  from  absorption  of  the  acid. 

Should  this  comparatively  mild  and  almost  painless  procedure  fail  to  produce  the  desired 
residt  of  removing  the  stain,  the  liquid  ethylate  of  sodium  may  be  rubbed  into  the  skin  by 
means  of  a  glass  rod.  This  wiU  destroy  the  epidermis  and  leave  a  raw  surface  which  becomes 
quickly  covered  with  a  thin  blackish  crust.  A  few  repetitions  of  this  application,  which 
causes  considerably  more  pain  than  the  carbolic  acid,  will  destroy  the  redness  in  great  part 
and  leave  a  cicatricial  condition  of  the  skin  which  is  almost  imperceptible. 

In  some  cases  I  have  dotted  the  surface  of  a  nsevus  with  nitric  acid,  which  has  the  effect 
of  lessening  the  red  color,  but  is  more  apt  to  leave  the  skin  rough  or  uneven  when  applied  to 
a  large  patch.  Moreover,  if  this  acid  is  carelessly  handled  and  an  ulcer  forms  in  conse- 
quence, the  resulting  cicatrix  may  become  raised  above  the  surface  of  the  skin  and  present 
an  unsightly  appearance. 

Cauterization  of  the  surface  of  the  wine-mark  by  the  means  of  a  double-canvex  lens  or 
"burning  glass,"  has  been  highly  recommended  as  a  curative  measure.  Here  again  the  pro- 
ds?) 


DISEASES  OF  TRE  SKIN— E EOF  LAST IC. 

duction  of  ulceration  must  be  carefully  avoided.  I  have  never  tested  tMs  method  of  treat- 
ment, but  in  one  case  thus  treated,  which  I  saw  some  years  ago,  the  cheek  was  covered  by 
numerous  keloidal  elevations  as  the  result  of  the  solar  operations.  In  one  case  ef  extensive 
njevus  I  have  known  the  galvano-cautery  to  be  cautiously  used  with  the  effect  of  partially 
obliterating  the  vessels  and  leaving  a  smooth  sui'face. 

The  treatment  of  wine-mark  by  linear  scarification  was  proposed  by  Squire,  of  London, 
a  few  years  ago,  and  on  account  of  the  novelty  of  the  method  and  the  positive  assertions  as 
to  its  great  value,  various  dermatologists  in  Europe  and  America  were  led  to  test  its  merits. 
The  reports  made  by  these  were  not  at  all  favorable  to  the  plan  of  treatment,  and  so  far  as  I 
am  aware  no  one  but  the  author  of  the  operation  has  succeeded  in  removing  a  wine-mark  by 
scarification.  In  my  hands  it  has  failed  to  accomplish  the  desired  result,  but  still  I  am  not 
prepared  to  condemn  the  operation  as  others  have  done,  but  deem  it  possible  that  the  failure 
in  many  cases  reported  has  resulted  from  a  lack  of  experience  in  the  performance  of  the 
operation,  which  necessarily  requires  great  care  and  skill.  Possibly  the  claims  first  made 
for  the  operation  were  based  upon  an  enthusiastic  belief  in  its  value  rather  than  upon  a  de 
liberate  study  of  results  in  numerous  cases. 

The  operation  of  linear  scarification  as  proposed  by  Squire  consists  in  first  freezing  a  por. 
tion  of  the  affected  skin  by  means  of  ether  spray  and  then  making  parallel  incisions  with  a 
thin  scalpel  or  an  instrument  composed  of  a  dozen  or  more  blades  and  called  the  "multiple 
scarifier."  The  cuts  should  be  no  more  than  a  sixteenth  of  an  inch  apart,  and  as  long  as 
they  can  be  made  quickly  and  straight.  The  bleeding  is  slight  if  the  cuts  are  not  over  a 
sixteenth  of  an  inch  in  depth,  and  can  easily  be  arrested  by  applying  a  piece  of  blotting 
paper  and  slight  pressure.  This  piece  of  paper  should  be  gently  peeled  off  before  it  has 
dried,  and  in  the  direction  of  the  incisions.  Squire  says:  "If  the  little  operation  be  exe- 
"  outed  cleverly,  that  is  to  say,  if  the  skin  is  weU  frozen,  the  instrument  exquisitely  sharp, 
"  the  incisions  made  with  perfect  regularity  of  spacing  and  with  uniform  equality  of  depth, 
"and  a  special  care  be  taken  to  avoid  any  accidental  dragging  of  the  strips  apart,  so  that  no 
"clot  is  formed  in  the  incisions  ;  if  such  detaUs  be  well  cared  for,  it  wUl  be  found  that  the 
"  cuts  Ileal  with  surprising  rapidity  and  became  within  a  few  days  quite  invisible.  The  pro- 
"  cess  of  scarification  must  be  many  times  repeated,  at  intervals  of  a  few  days,  that  is  to  say, 
"as  soon  as  the  last  cuts  are  healed.  At  each  operation  the  direction  of  the  parallels  of  the 
"  second  operation  should  be  oblique  to  those  of  the  first  operation,  and  so  on.  The  process 
"  is  a  tedious  one,  but  the  result  of  it  is  highly  satisfactory,  for  the  stain  is  made  to  disap- 
"  pear  without  the  production  of  a  scar." 

The  tattooing  of  nsevus  by  needles  immersed  in  carbolic  acid  has  been  recommended  by 
Sherwell,  and  I  have  seen  patches  lightened  in  color  by  this  method  of  treatment.  Owing 
to  the  difficulty,  however,  of  getting  the  acid  in  any  amount  beneath  the  surface  of  the  skin 
this  plan  will  be  found  much  less  effective  than  the  use  of  needles  connected  with  a  galvanic 
battery. 

The  electroljiic  treatment  of  wine-mark  I  have  practiced  during  the  last  five  years,  and 

(168) 


ANGIOMA. 

although  I  cannot  claim  that  the  operation  accomplishes  all  that  conld  be  desired,  I  hc^ve 
repeatedly  succeeded  in  transforming  a  dark  and  unsightly  stain  into  a  smooth  patch  of  a 
light  pink  hue.  The  object  aimed  at  in  the  treatment  of  wine-mark  by  electrolysis,  as  in  the 
case  of  scarification  and  puncture,  is  to  excite  sufficient  inflammation  to  destroy  the  fine  net- 
work of  blood  vessels.  As  the  galvanic  current  is  more  active  and  at  the  same  time  more 
manageable  than  acid  adhering  to  the  points  of  needles,  it  is  not  strange  that  this  method 
should  produe  the  desired  effect  in  the  speediest  manner  and  with  the  least  injury  to  the  sur- 
face of  the  skin. 

The  operation  is  somewhat  similar  to  that  already  described  in  the  treatment  of  hyper- 
trichosis (page  188).  A  single  needle,  or  a  number  of  needles  combined  in  one  instrument, 
is  attached  to  the  negative  cord  of  a  constant  current  battery  and  inserted  into  the  skin  by 
a  quick  pressure.  The  electrolytic  action  which  ensues  upon  the  completion  of  the  circuit 
serves  to  destroy  to  a  certain  extent  the  fine  plexus  ol  superficial  vessels  which  constitutes  the 
red  mark. 

ANG-IOMA. 

The  term  Angioma  is  often  used  as  a  generic  title,  applicable  to  all  new  growths  of  blood 
vessels  and  lymphatics.  As  the  termination  of  the  word  indicates  a  tumor  it  would  seem 
more  convenient  to  restrict  its  application  to  erectile  tumors  composed  of  blood  vessels.  To 
this  condition  the  distinctive  name  of  Angioma  cavernosum  has  been  applied. 

The  angiomatous  tumor  is  sometimes  congenital  but  usually  develops  shortly  after  birth. 
During  childhood  it  may  reach  a  sufiicient  size  to  cause  gi-eat  deformity  and  annoyance.  It 
is  composed  of  a  net- work  of  trabeculse,  the  interspaces  representing  dilated  blood  vessels 
and  freely  communicating  with  each  other.  The  margin  of  the  growth  may  be  abrupt  or 
gradually  shade  off  into  healthy  tissue.  The  tumor  is  soft  and  compressible,  but  the  blood 
returns  as  soon  as  the  pressure  ceases.  The  color  of  the  tumor  varies  from  a  dull  red  to  a  dark 
purple  in  accordance  with  the  arterial  or  venous  character  of  the  contained  blood. 

Angioma  may  be  single  or  multiple,  although  the  former  is  usually  the  case.  It  is  most 
frequently  observed  upon  the  scalp  and  face.  The  lips,  eyelids  and  lobe  of  the  ear  are 
affected  mth  especial  frequence.  The  course  of  the  affection  is  variable.  "WhUe  in  many 
cases  the  growth  remains  stationary  after  having  reached  a  certain  age,  in  other  cases  it  con- 
tinues to  enlarge  and  sometimes  manifests  a  tendency  to  become  inflamed  and  even  gangre- 
nous. 

Treatment.  The  first  step  to  be  taken  in  the  treatment  of  an  angiomatous  tumor  occur- 
ring in  infancy  is  to  watch  it  carefully  untU  a  tendency  to  an  increase  in  size  becomes  evi- 
dent. In  this  case  operative  treatment  is  always  advisable.  If  the  growth  is  no  larger  than 
a  half  cherry  and  the  child  has  not  been  vaccinated,  this  operation  may  be  performed  ui)on 
the  surface  of  the  tumor  which  is  apt  to  be  destroyed,  wholly  or  in  part,  by  the  resulting 
inflammation.    If  the  tumor  is  so  situated  that  constant  pressure  can  be  exerted  upon  it  for 

(159) 


DISEASES  OF  THE  SKIN.— NEOPLASTIC. 

several  weeks,  this  plan  may  be  adopted  with,  the  hope,  if  not  the  certainty,  of  obliterating 
the  dilated  vessels.  A  more  effective  plan  of  treatment  consists  in  the  repeated  injection  of 
a  few  drops  of  carbolic  acid  by  means  of  a  fine  hypodermic  syringe.  When  the  growth  is  of 
considerable  size  electrolysis  may  be  employed  with  success,  or  red  hot  needles  be  thrust  into 
the  tumor.  Ordinary  needles  may  be  heated  by  means  of  a  spirit  lamp  and  used,  but  the 
fine  loop  of  platinum  wire  connected  with  a  galvano-caustic  battery  is  much  preferable. 

LUPUS  VULGARIS. 

Lupus  is  a  chronic  affection,  presenting  circumscribed,  duU  reddish  patches  of  diseased 
skin,  which  tend  to  ulcerate,  and  invariably  leave  a  scar.  Except  in  its  severe  forms  there  is 
a  notable  absence  of  pain,  itching  and  other  subjective  sensations.  The  disease  runs  a  vari- 
able course  in  different  cases,  and  presents  variations  in  appearance  at  different  stages.  The 
most  characteristic  lesion  is  a  small  yellowish-red  papule,  which  can  frequently  be  noted  at 
the  margin  or  in  the  vicinity  of  a  patch.  It  is  not  present  in  all  cases.  Sometimes  the  dis- 
ease begins  as  a  dull  reddish  macule,  which  becomes  slightly  elevated  and  scaly  as  it  increases 
in  si2e.  This  mUd  or  erythemato-squamous  form  of  the  disease  may  occur  in  one  or  in 
several  patches  of  irregular  form.  It  creeps  slowly  over  the  surface  attacked,  and  in  many 
cases  disappears  without  ulceration.  The  cellular  infiltration,  however,  usually  produces  a 
certain  amount  of  atrophy  of  the  skin,  and  being  absorbed,  leaves  a  more  or  less  distinct 
cicatrix.  When,  as  is  commonly  the  case,  the  disease  develops  by  the  aggregation  of  small, 
solid  papules,  the  patches  usually  present  an  elevated,  crescentic  and  sometimes  a  scalloped 
border.  Not  unfrequently  a  prominent  ridge  of  infiltrated  skin  will  be  seen  surrounding  a 
tolerably  smooth,  and  in  some  cases,  a  cicatricial  center.  As  the  papules  of  lupus  increase  in 
size  and  become  tubercular  they  evince  a  marked  tendency  to  soften,  and  to  form  small  ulcers, 
especiaUj'  at  the  advancing  border  of  the  patch.  This  now  will  present  a  reddened  and  scaly 
surface,  with  numerous  small  crusts  near  the  periphery  and  areas  of  cicatricial  tissue  in  the 
center.  When  the  cellular  growth  invades  the  deeper  portion  of  the  skin  ulceration  is  likely 
to  occur,  sometimes  assuming  a  serpiginous  form,  and  often  proving  difficult  to  heal.  The 
face  is  the  favorite  seat  of  the  disease,  and  the  cheeks,  upper  lip  and  wings  of  the  nose  are 
affected  with  great  frequency.  It  also  occurs  on  the  scalp,  trunk,  and  particularly  on  the 
backs  of  the  hands  and  fingers.  The  mucous  membrane  of  the  oral  and  nasal  cavities  may 
be  affected  coincidently  with  the  skin. 

The  disease  is  never  congenital,  and  rarely,  if  ever,  hereditary.  It  generally  develops  in 
childhood  or  early  life,  although  I  have  noted  its  first  appearance  in  a  man  of  sixty.  The 
sexes  suffer  with  about  equal  frequency. 

Lupus  is  regarded  by  some  writers  as  being  invariably  a  cutaneous  manifestation  of 
scrofula.  It  surely  occurs  in  some  patients  who  are  far  from  presenting  signs  of  a  strumous 
diathesis.  On  the  other  hand,  scrofulous  abscesses  often  lead  to  an  ulcerative  process  in  the 
skin  (scrofuloderma),  which  surely  ought  not  to  be  designated  as  lupus.

LUPUS  VULGARIS. 

Diagnosis.     The  diagnosis  of  lupus  is  generally  easy,  but  the  tubercular  and  ulcerative 
forms  of  the  disease  sometimes  bear  such  a  strong  resemblance  to  syphilis  that  nothing  but 
experience  in  the  treatment  of  the  two  diseases  will  enable  one  to  decide  as  to  the  nature  of  the 
case.     The  age  of  the  eruption  is  of  the  greatest  importance  in  arriving  at  a  conclusion,  since 
the  lupus  is  a  disease  of  slow  progress,  while  the  cutaneous  manifestations  of  syphilis  develop 
with  considerable  rapidity.     If  a  patch  of  tubercles  or  an  ulcer  on  the  face  is  of  doubtful 
nature,  it  may  be  considered  syphilitic  if  it  is  extensive  and  has  developed  within  a  few 
months,  while,  if  it  has  existed  without  much  change  for  several  years,  it  is  assuredly  lupus. 
Treatment.     Lupus  is  by  no  means  the  incurable  disease  which  the  majority  of  physi- 
cians think  it  to  be,  provided  the  patient  will  submit  gracefully  to  the  proper  treatment. 
This  is  simple,  though  in  many  cases  it  is  of  necessity  somewhat  heroic.     The  quickest  way 
to  cure  the  disease  is  to  destroy  it,  and  the  scar  resulting  from  treatment  will  probably  be 
much  less  unsightly  than  that  which  would,  in  time,  result  from  the  ravages  of  the  disease. 
Scarring,  indeed,  is  inevitable  in  all  cases  save  the  most  superficial.     These  mild  cases  may 
sometimes  be  successfully  treated  by  the  employment  of  vigorous  soap  frictions,  and  the 
application  of  highly  stimulating  ointments,  but  usually  more  severe  measures  are  required. 
In  lupus  we  have  a  new  growth  in  the  skin,  which  manifests  a  marked  tendency  to  spread 
and  invade  healthy  tissue.     The  main  object  of  treatment  must  therefore  be  the  destruction 
or  removal  of  this  growth.     When  taken  in  its  incipient  stage  this  can  be  readily  accom- 
plished.    If,  however,  lupus  has  increased  to  such  an  extent  as  to  involve  a  considerable 
amount  of  tissue,  its  successful  treatment  is  by  no  means  a  trivial  matter.     Half-way  meas- 
ures are  often  worse  than  useless.     In  very  many  cases  the  attempts  to  heal  the  ulceration, 
or  remove  the  nodules  by  daily  cauterization,  have  only  stimulated  the  progress  of  the  dis- 
ease.    It  is  better  to  do  nothing  than  to  irritate  the  part  by  applications  which  tend  more  to 
inflame  the  healthy  skin  than  to  destroy  the  morbid  growth.     At  the  same  time  it  is  not 
always  necessary,  and  in  lupus  of  the  face  it  is  often  unadvisable  to  attempt  to  remove  the 
growth  in  a  single  operation.     In  treating  lupus,  our  object  is  not  only  to  remove  the  dis- 
eased tissue,  but  to  do  so  in  such  a  manner  as  will  occasion  the  least  amount  of  disfigurement. 
A  relapse  of  the  disease  after  an  operation  is  considered  by  some  surgeons  to  reflect  discredit 
upon  the  operator.     But  in  the  treatment  of  lupus  of  the  face,  I  think  it  is  far  better  to 
remove  the  greater  portion  of  the  growth  at  the  first  operation,  and  to  tell  the  patient  that  a 
second  or  third  operation  will  probably  be  required,  in  order  to  avoid,  as  far  as  possible,  the 
production  of  a  disfiguring  scar.     Of  course,  if  the  patient  desires  the  removal  of  the  growth 
in  one  operation,  this  can  be  accomplished,  but  in  many  cases  I  should  not  advise  it. 

Formerly,  it  was  the  custom  to  use  the  knife  freely  in  the  treatment  of  lupus,  and  no  one 
can  doubt  the  success  which  was  attained  by  this  method,  but  the  resulting  scar  was  usually 
large  and  deep.  With  the  means  now  at  our  disposal,  it  is  only  in  rare  cases  that  we  resoit 
to  the  knife.  When  lupus  invades  the  lower  eyelid,  as  it  freqently  does,  a  plastic  opei"ation 
may  be  necessary,  in  order  to  fill  up  the  gap  made  by  the  removal  of  the  diseased  tissue; 
but  when  no  such  indications  exist,  a  sharp  spoon  or  curette  is  an  instrument  of  far  less  ter- 
pen

ror  to  the  patient,  and  of  far  greater  utility  in  the  hands  of  the  surgeon,  than  the  knife. 
WTiether  we  have  a  group  of  tubercles  with  an  unbroken  epidermis,  or  a  patch  of  ulceration, 
we  can  remove  the  diseased  tissue  by  means  of  a  curette  with  the  greatest  ease,  and  with  a 
slight  amount  of  pain.  Unless  the  patient  is  aged,  or  weak,  or  has  very  little  courage,  the 
growth,  if  small  or  of  moderate  size,  can  be  removed  without  the  use  of  an  anaesthetic.  In 
cases  requiring  anaesthesia,  nitrous  oxide  gas  is  usually  preferable  to  ether  or  chloroform. 
The  scraping  operation  can  be  performed  much  more  quickly  than  excision,  and  while  the 
nitrous  oxide  may  be  safely  inhaled  for  a  half -hour  or  more,  a  few  minutes  of  anaesthesia  is 
often  all  that  is  required,  and  then  much  time  is  wasted  and  trouble  occasioned  by  the  use  of 
ether. 

In  a  number  of  cases  I  have  resorted  to  the  use  of  local  anaesthesia  with  good  effect.  By 
the  use  of  an  ether  spray  produced  by  means  of  a  hand-ball,  the  part  to  be  operated  upon  can 
be  kept  in  a  half -frozen  and  almost  insensible  condition.  The  spray  at  the  same  time  washes 
away  the  diseased  tissue  as  fast  as  it  is  loosened  by  the  curette,  leaving  the  surface  clear  and 
thus  rather  facilitating  the  operation  than  otherwise.  To  one  who  has  had  no  experience 
with  the  use  of  the  curette,  the  ease  with  which  the  morbid  tissue  can  be  scraped  away  is 
quite  surprising.  The  lupous  nodules,  although  feeling  firm  to  the  touch,  are  much  softer 
than  the  surrounding  skin,  and  are  scraped  out  of  the  corium  by  the  employment  of  very 
little  force.  After  some  experience  with  this  instrument,  one  learns  to  recognize  the  peculiar 
sensation  which  is  imparted  to  the  touch,  when  the  instrument  comes  in  contact  with  per- 
fectly healthy  skin.  Should  no  steps  be  taken  further  than  scraping  out  the  morbid  growth, 
a  relapse  is  almost  certain  to  occur,  especially  if  the  disease  has  existed  for  any  considerable 
time,  and  has  invaded  the  deeper  portion  of  the  skin  ;  it  is  therefore  always  advisable  to 
cauterize  the  raw  surface  left  after  thorough  scraping,  or  to  apply  some  powder  or  paste, 
which  will  be  likely  to  destroy  the  vitality  of  the  lupous  cells  which  may  remain.  Of  the 
various  caustics  which  have  been  employed,  I  have  found  the  application  of  the  chloride  of 
zinc  to  be  most  efficacious,  but  the  pain  which  it  occasions  is  a  serious  objection  to  its  use. 
The  actual  or  thermo-cautery  has  been  highly  recommended,  but  I  have  seen  lupous  nodules 
reappear  so  many  times  after  its  use,  that  I  cannot  recommend  it.  Pyrogallic  acid  in  the 
form  of  a  twenty  per  cent,  ointment,  I  have  used  as  an  application  after  scraping,  and  with 
good  results.  A  mixture  of  equal  parts  of  arsenious  acid  and  gum  acacia,  made  into  a  paste 
with  a  few  drops  of  water,  is  very  beneficial,  inasmuch  as  it  tends  to  destroy  only  the  morbid 
tissue  ;  but  its  use  is  followed  by  severe  pain,  which  lasts  for  several  hours.  When  the  patch  is 
not  of  long  standing,  and  is  superficial  in  its  seat,  the  application  of  iodoform  after  scraping 
is  the  plan  which  I  would  recommend.  It  is  painless,  and  like  the  arsenical  paste,  tends  to 
destroy  the  lupous  cells  and  promotes  the  speedy  healing  of  the  ulceration.  If,  on  the  other 
hand,  the  growth  is  of  long  standing,  and  the  nodules  are  deeply  seated  in  the  corium,  the 
use  of  a  cone  of  nitrate  of  silver  is,  in  my  opinion,  the  best  adjuvant  to  the  curette.  The 
point  of  nitrate  of  silver  cone  should  be  pressed  firmly  in  different  directions  into  the  small 
pits  left  after  the  removal  of  the  nodules.     This  procedure  will  usually  serve  to  destroy  the 

(102)

LUPUS  ERYTHEMATOSUS. 

foci  of  the  disease,  which  would  otherwise  certainly  occasion  a  relapse  in  the  course  of  a  few 
months. 

After  the  removal  of  a  patch  of  lupus,  by  means  of  the  curette  and  the  employment  of 
one  of  the  applications  already  mentioned,  the  process  of  healing  is  usually  speedy,  and  a 
tolerably  smooth  cicatrix  will  result.  A  relapse  may  be  looked  for  at  any  time  during  the 
year  follomng  the  operation,  and  should  it  occur,  the  morbid  growth  will  appear  in  the  form 
of  one  or  more  brownish-red  papules  springing  up  at  the  edge,  or  in  the  midst  of  the  cicatri- 
cial tissue.  A  second  operation  then  becomes  necessary.  But  now  it  is  comparatively  a  sim- 
ple matter  to  dig  out  these  foci  of  the  disease  by  means  of  a  curette  of  small  size,  and  to 
thrust  in  a  cone  of  nitrate  of  silver. 

Multiple  puncture  and  linear  scarification  are  methods  of  treatment  which  have  beeu 
highly  recommended  by  European  writers. 

The  latter  is  of  the  greatest  value  in  cases  of  lupus  of  the  face,  where  it  is  desirable  to 
leave  as  smooth  and  non-contractile  a  scar  as  possible.  A  very  sharp  kidney-shaped  Icnife  is 
most  serviceable  for  the  purpose  of  scarification,  and  the  cuts  should  be  made  as  close  to- 
gether as  they  can  be  made  and  stiU  remain  parallel.  The  hemorrhage  can  be  speedily 
checked  by  the  pressure  of  a  wad  of  absorbent  cotton,  and  the  operation  can  be  repeated  in 
a  week  or  ten  days,  the  parallel  cuts  being  now  made  in  a  transverse  direction.  The  pain 
occasioned  is  inconsiderable  if  the  knife  is  sharp,  but  in  certain  cases  it  may  seem  advisable 
to  previously  rub  the  patch  with  oleate  of  cocaine,  which  deadens  the  sensibility  of  the  skin 
to  a  slight  extent. 


LUPUS   ERYTHEMATOSUS. 

Lupus  erythematosus  is  an  affection  closely  allied  to  lupus  vulgaris,  but  commonly  re. 
garded  as  a  distinct  disease.  It  is  characterized  by  the  superficial  character  of  the  cellular 
infiltration  and  the  tendency  to  involve  the  sebaceous  follicles.  Unlike  the  common  lupus 
already  described,  this  comparatively  rare  form  does  not  tend  to  ulceration,  although,  when 
the  infiltration  is  sufficient  to  produce  atrophy  of  the  skin,  a  cicatricial  surface  results.  The 
name  lupus  erythematosus  is  an  unfortunate  one,  since  the  common  lupus  {L.  vulgaris)  i.s 
frequently  superficial  and  erythematous,  and  confusion  has  arisen  from  a  restricted  use  of 
the  adjective.  The  distinctive  peculiarity  of  the  variety  of  lupus  now  under  consideration 
being  the  involvement  of  the  sebaceous  glands,  it  would  be  far  better  to  employ  a  term  such 
as  lupus  seiaceus  or  lupus  acneiformis.  Hebra,  who  first  described  this  peculiar  affection 
of  the  skin  in  1845,  gave  to  it  the  name  Seborrhoea  congestiva,  but  later  saw  fit  to  class  it  as 
a  form  of  lupus. 

The  course  of  the  disease  is  notably  chronic.  In  rare  instances  it  has  been  observed  to 
attack  a  large  extent  of  cutaneous  surface  like  an  acute  eruption,  and  to  be  accompanied 
■nath  severe  constitutional  symptoms.  Frequently  injudicious  treatment  or  some  other  cause 
may  induce  a  patch  of  long  standing  to  become  acutely  congested.     Such  an  exacerbation  of 

(163) 


DISEASES  OF  THE  SKIN.— NEOPLASTIC 

the  disease  is  often  coincident  with  the  development  of  new  lesions.  As  a  rule  the  affection 
exerts  no  perceptible  influence  on  the  general  health  of  the  patient.  It  is  far  more  likely 
than  the  common  form  of  lupus  to  be  accompanied  by  subjective  sensations,  such  as  burning 
or  even  a  slight  itching.  The  disease  usually  makes  its  appearance  in  the  form  of  small,  red, 
pin-head  sized  macules,  which  wiU  not  quite  disappear  on  pressure.  They  present  slight  de- 
pressions in  the  center,  where  the  sebaceous  follicles  open  upon  the  surface  of  the  skin,  or, 
as  is  usually  the  case,  these  minute  pits  are  filled  with  fine,  adherent,  fatty  scales.  These 
characteristic  primary  lesions  may  be  disseminated  or  grouped.  In  the  latter  case  they  form 
patches  of  a  dull  reddish  or  violaceous  hue,  dotted  with  numerous  whitish  points,  or  covered 
with  fine  adherent  scales,  which,  when  gently  raised,  show  prolongations  from  the  under 
surface  corresponding  to  the  sebaceous  follicles.  The  patches,  of  which  there  may  be  one  or 
several,  are  usually  sharply  defined.  They  may  have  an  irregular  outline,  with  primary 
efflorescences  scattered  about  the  margin,  or  be  circular  in  form,  in  which  case  they  are  apt 
to  become  depressed  as  the  disease  progresses.  The  disease  almost  invariably  attacks  the 
face.  Occurring,  as  it  frequently  does,  upon  the  bridge  of  the  nose,  and  extending  laterally 
upon  either  cheek,  the  configuration  of  the  patch  is  suggestive  of  a  butterfly  with  outspread 
wings. 

Like  the  vulgar  form,  lupus  erythematosus  is  sometimes  associated  with  indications  of 
struma.  It  is  more  frequently  met  with  in  females,  and  in  this  sex  is  more  apt  to  run  a  se- 
vere course.     It  does  not  develop  in  childhood,  as  does  lupus  vulgaris. 

Di.vGxosis.  It  is  often  quite  difficult  to  distinguish  lupus  erythematosus  from  the  super- 
ficial or  erythemato-squamous  form  of  lupus  vulgaris.  But  since  the  nature  of  these  two 
affections  is  almost  identical  and  a  somewhat  similar  treatment  required  in  either  case,  the 
differential  diagnosis  is  not  of  the  highest  importance.  Still,  it  is  well  to  bear  in  mind,  that, 
whereas  one  affection  has  numerous  white  specks,  or  in  some  cases  minute  horny  projections 
upon  the  diseased  surface,  the  other  presents  small  papules,  and  at  a  more  advanced  stage, 
tubercles,  pustules  and  ulcers.  The  age  of  the  patient  may  furnish  a  clew,  as  only  the  com- 
mon variety  of  lupus  is  met  with  before  the  age  of  adolescence.  A  patch  of  chronic  eczema 
of  the  face,  or  rosacea,  might  be  mistaken  for  erythematous  lupus,  and  harm  result  from  the 
unnecessary  use  of  caustic  applications.  But  these  affections  have  not  the  sharp  border  of 
lupus,  and  while  the  former  differs  in  being  quite  itchy,  and  perhaps  moist  at  times,  the 
latter  may  be  recognized  by  the  development  of  tubercles  and  pustules. 

Teeatment.  In  the  treatment  of  this  affection,  whatever  will  improve  the  general 
health  of  the  patient  should  naturally  be  given  ;  it  may  be  iron  in  one  case,  cod-liver  oil  in 
another,  and  arsenic,  strychnia,  or  phosphorus  in  others.  The  latter  drug  seems  to  have  a 
specially  beneficial  effect  in  lessening  the  congestion  of  the  patches  and  promoting  a  tendency 
to  the  cicatrization  which  sometimes  occurs  spontaneously.  The  internal  use  of  the  iodide 
of  starch  in  lupus  erythematosus  has  recently  been  recommended  upon  good  authority  (An- 
derson). I  must  say  that  I  have  failed  to  see  any  beneficial  result  in  a  number  of  cases  in 
which  I  have  used  it,  although  I  regard  it  as  a  valuable  remedy  in  combatting  the  strumous 

(16-1) 


SCROFULODERMA. 

diathesis.  Tlie  local  treatment  is  of  the  highest  importance.  Frictions  with  green  soap  )nay 
be  at  first  used  to  remove  the  scales  and  to  promote  absorption  of  the  diseased  tissue.  Tar, 
sulphur,  and  other  stimulating  applications  may  now  be  used  with  more  or  less  effect,  but  a 
better  remedy  is  the  constant  application  of  adhesive  mercurial  plaster.  In  some  mild  cases 
this  will  effect  a  cure.  Generally,  however,  stronger  applications  are  called  for.  A  tincture 
of  iodine  of  double  strength  combined  with  an  equal  part  of  collodion,  may  be  used  as  a 
varnish,  and  renewed  as  often  as  it  peels. 

Where  the  infiltration  is  deep,  a  strong  solution  of  caustic  potash  may  be  applied  to 
successive  portions  of  the  patch.  In  severe  cases  the  dermal  curette  may  be  employed  to 
scrape  away  the  diseased  tissue,  and  the  raw  surface  very  lightly  touched  with  the  galvano- 
cautery.  When  active  congestion  is  present,  caustics  should  be  withheld  until  after  a  course 
of  soothing  applications  has  put  the  skin  in  a  less  irritable  condition.  Otherwise,  a  mild 
caustic  may  stimulate  rather  than  decrease  the  affection. 

The  most  efficient  plan  of  local  treatment  which  I  have  tried  and  the  one  suited  to  the 
greatest  number  of  cases  consists  in  the  application  of  pure  carbolic  acid. 

SCROFULODERMA. 

Synonym — Strumo-derma. 

The  term  scrofula  or  struma  has  long  been  employed  to  indicate  a  peculiar  constitutional 
disease  or  condition  of  the  system,  which  is  usually  inherited  and  manifested  in  early  life  by 
the  development  of  certain  characteristic  symptoms.  The  term  has  heretofore  had  a  wide 
application,  and  although  many  affections  of  the  skin  and  internal  organs  which  were  for. 
merly  called  scrofulous  are  now  regarded  as  not  in  the  least  dependent  upon  this  peculiar 
diathesis,  the  term  has  still  a  somewhat  indefinite  meaning,  and  cannot  be  precisely  defined. 
The  existence  of  the  disease  or  diathesis  cannot,  however,  be  denied,  and  must  be  taken  into 
account  in  the  treatment  of  ordinary  affections,  which  occurring  in  scrofulous  subjects  are 
apt  to  present  a  modified  form. 

The  affections,  which  most  frequently  indicate  a  scrofulous  habit,  and  especially  concern 
the  dermatologist,  are  indolent  inflammation,  and  caseous  degeneration  of  the  lymphatic 
glands  with  the  subsequent  formation  of  peculiar  cutaneous  ulcers.  This  pathological  pro- 
cess is  now  frequently  observed  upon  the  neck  of  young  persons,  who  often  present  other 
manifestations  of  the  scrofulous  diathesis.  These  may  be  either  a  thick  and  doughy,  or  an 
abnormally  delicate  and  transparent  skin,  a  tumefaction  of  the  belly  and  a  marked  tendency  to 
chronic  keratitis,  otorrhoea  and  coryza.  In  the  cervical  region,  the  glands  upon  one  or  both 
sides  slowly  enlarge  and  become  firm  or  doughy  to  the  touch.  The  skin  at  this  time  is  unaf- 
fected and  there  is  little  or  no  pain  experienced  by  the  patient.  Nor  is  the  glandular  swelling 
attended  by  the  ordinary  symptoms  of  inflammation.  After  this  condition  has  existed  for 
many  months,  or  perhaps  years,  a  gradual  suppurative  softening  of  the  glandular  tissue 
takes  place,  the  tumors  increase  in  size  and  become  more  or  less  painful.     The  skin  now 

(166) 


DISEASES  OF  THE  SKIN— NEOPLASTIC. 

assumes  a  dull  red  or  purplish,  hue,  and  becomes  thinner  at  one  or  more  points  until  the  fluc- 
tuating abscess  is  partially  evacuated  by  the  formation  of  a  sinus  or  ulcer.  The  discharge 
which  at  first  is  sero-pumlent  and  mingled  with  caseous  matter,  gradually  grows  thinner, 
and  persists  for  a  long  time  unless  treatment  is  instituted.  At  last  the  skin  heals  and  leaves 
a  puckered  and  disfiguring  cicatrix.  A  number  of  glands  iu  the  cervical  chain  are  often 
simultaneously  affected.  At  a  given  time  some  of  these  may  be  discharging  or  covered  by  a 
thin  blackish  crust,  while  others  are  unbroken  or  completely  cicatrized. 

Other  forms  of  scr^iuloderma  have  been  described  in  which  disseminated  pustules  re- 
sembling acne  have  developed  upon  the  trunk,  run  an  extremely  indolent  course,  and  left 
numerous  circular,  depressed  or  "  punched-out "  cicatrices. 

The  cause  of  scrofula  is  an  inherent  tissue  debUity,  which,  is  usually  transmitted  from 
one  generation  to  another  and  is  undoubtedly  fostered  by  lack  of  pure  air  and  proper  food 
and  by  the  consanguineous  marriages  of  affected  individuals.  In  the  negro  race  it  is  much 
more  common  than  among  the  whites.  It  has  been  recently  claimed  that  scrofula  and  tuber- 
culo-sis  are  intimately  related  and  dependent  upon  an  infection  of  the  system  by  the  bacUlus 
described  by  Koch. 

Diagnosis.  Occurring  upon  the  neck  in  connection  with  swollen  glands  the  ulceration 
of  scrofuloderma  is  readUy  recognized  as  such.  Upon  other  portions  of  the  body  the  scrofu- 
lous ulcer  which  results  from  an  infiltration  of  the  skin  by  small  celled  mases  of  granulation 
tissue  is  apt  to  be  mistaken  for  a  syphilitic  gummatous  ulcer.  The  co-existing  evidences  of 
scrofula,  or  of  syphilis,  or  a  resort  to  specific  treatment  must  often  be  relied  upon  to  settle 
the  diagnosis. 

Upon  the  backs  of  the  hands  a  cheesy  degeneration  of  the  skin  sometimes  occurs  as  a 
result  of  the  inherited  scrofulous  taint,  and  bears  a  strong  resemblance  to  lupus  vulgaris. 
There  is,  however,  an  absence  of  the  small  brownish  nodules  of  lupus,  and  a  marked  ten- 
dency of  the  patches  to  assume  a  verrucous  condition. 

Treatjiknt.  The  internal  remedies  which  have  found  favor  in  the  treatment  of  scrofu 
loderma  are  cod-liver  oil,  iodine,  especially  in  the  form  of  iodide  of  iron  or  iodide  of  starch, 
lime,  phosphorus  and  chlorate  of  potash.  In  spite  of  their  undoubted  value  in  certain  cases, 
too  much  reliance  should  not  be  placed  upon  these  drugs  to  the  exclusion  of  a  strict  hygi- 
enic regimen.  Without  proper  food  and  plenty  of  open-air  exercise,  internal  medication 
will  prove  of  little  value. 

The  local  treatment  of  scrofuloderma  consists  in  the  application  of  ointments  or  lotions 
of  mercury,  iodine  or  iodoform  to  the  hard  and  swollen  glands,  the  excision  or  curetting  of 
softened  and  suppurating  tumors,  and  the  application  of  iodoform  in  powder  and  ethereal 
solution  to  scrofulous  ulcerations.

Syphilis  is  a  specific,  contagious  disease,  which  is  either  inherited  or  acquired  during  life 
through  the  absorption  of  a  poisonous  secretion  from  a  person  already  suffering  from  the 
disease.  The  acquired  form  invariably  manifests  itself  at  the  outset  by  the  development  of 
a  peculiar  lesion  upon  the  skin  or  mucous  membrane  at  the  point  where  inoculation  has  taken 
place.  The  evolution  of  syphilis  is  slow  and  irregular,  often  lasting  for  a  lifetime,  but  in 
many  respects  the  disease  bears  a  resemblance  to  the  acute  exanthemata.  It  sometimes  runs 
its  course  in  a  few  years,  leaving  the  patient  apparently  in  perfect  health,  and  although  it 
commonly  occurs  but  once  in  a  lifetime,  there  are  numerous  authenticated  instances  of  syph- 
ilitic re-infection. 

The  nature  of  the  so-caHed  virus,  or  infectious  principle  of  a;n  inoculable  syphilitic 
secretion,  is  as  yet  unknown.  How  it  produces  the  characteristic  symptoms  of  the  disease 
is  equally  obscure.  Various  experimenters  have  discovered  by  microscopical  observation 
various  fungi,  corpuscles  and  bacterial  germs  which  they  have  thought  to  be  the  source  of 
infection,  but  their  views  have  so  far  failed  to  meet  with  general  approbation,  and  we  are 
forced  to  admit  that  we  only  know  the  infecting  principle  of  syphilis  from  a  study  of  its 
effects. 

The  blood  of  syiDhilitic  patients  throughout  the  earlier  period  of  the  disease  or  the 
secretion  taken  from  the  surface  of  the  moist  syphilitic  lesions  is  well  kno^vn  to  be  capable 
of  producing  syphilis  in  a  person  who  has  not  already  been  inoculated,  provided  it  is  applied 
to  a  surface  capable  of  absorbing  the  same.  This  inoculation  has  been  perfonned  intention- 
ally with  a  positive  result  and  the  unintentional  transmission  of  the  disease  in  this  manner 
may  be  studied  in  very  many  cases.  Upon  an  unbroken  epidermis  the  blood  or  virulent 
secretion  may  be  applied  without  the  production  of  a  primary  syphUitic  lesion,  such  as  fol- 
lows successful  inoculation.  Moreover,  the  physiological  secretions  of  a  syphilitic  subject, 
such  as  saliva,  urine,  milk  and  semen,  as  weU  as  pathological  secretions,  such  as  pus  unmixed 
with  blood,  appear  to  contain  no  virus,  and  hence  may  be  inoculated  without  result. 

The  initial  lesion  or  chancre,  which  develops  at  the  point  of  inociilation,  is  most  fre- 
quently met  with  upon  the  genitals,  but  may  occur  upon  any  portion  of  the  skin  or  mucous 
membrane.  Extra-genital  chancres  are  not  unfrequently  observed  upon  the  fingers,  lips  and 
within  the  oral  cavity  and  upon  the  breasts  of  nurses.  This  lesion  assumes  a  variety  of  clini. 
cal  appearances  depending  more  or  less  upon  its  location,  and  may  consist  of  a  dry  or  moist 
papule,  or  assume  the  form  of  an  ulcer.  In  all  cases  the  lesion  is  characterized  by  mure  or 
less  induration  of  the  subjacent  tissue  which  serves  to  distinguish  it  from  the  chancroid  or 
"soft  chancre,"  which  is  generally  regarded  as  a  local  venereal  sore  and  incapable  of  infect- 
ing the  patient  with  a  constitutional  disease.  The  initial  lesion  of  syphilis  appears  usually 
three  weeks  or  thereabouts  after  an  impure  intercourse,  but  this  period  of  incubation  may 

(167) 


DISEASES  OF  THE  SKIN.— NEOPLASTIC. 

vary  between  two  and  eight  weeks.  In  this  respect  the  lesion  differs  notably  from  the  chan- 
croid which  is  commonly  noticed  within  a  day  or  two  after  inoculation. 

Following  the  development  of  the  chancre  the  neighboring  lymphatic  glands  become 
more  or  less  enlarged  and  indurated  within  two  weeks.  One  or  more  glands  may  be  notably 
affected  and  readily  felt  beneath  the  skin.  They  are  not  usually  painful  and  rarely  suppu- 
rate. About  a  month  later  a  general  engorgement  or  induration  of  all  the  subcutaneous 
glands  may  be  observed.  Those  situated  in  the  neck  along  the  posterior  border  of  the  ster- 
no-mastoid  muscle  and  those  along  the  inner  surface  of  the  arm,  together  with  the  inguinal 
glands  can  be  most  plainly  felt. 

At  this  time  there  is  apt  to  occur  a  group  of  new  symptoms,  consisting  of  a  slight  rise 
In  temperature  (the  syphilitic  fever),  an  intense  and  prolonged  headache,  a  painful  con- 
dition of  certain  of  the  larger  joints  and  an  outbreak  of  a  macular  eruption  upon  the 
skin.  During  the  next  few  months  the  macular  eruption  usually  merges  into  or  is  suc- 
ceeded by  a  papular,  pustular  or  disseminated  tubercular  eruption  or  a  succession  of  eruptions 
may  appear  upon  the  skin.  With  the  earliest  eruption  there  is  usually  a  soreness  of  the  throat 
with  perhaps  a  few  erosions  upon  the  soft  palate.  The  arthritic  pains  are  apt  to  be  quite 
troublesome,  espciaUy  at  night.  The  hair  of  the  scalp  becomes  loosened  to  a  greater  or  less 
degree,  and  often  falls  in  considerable  quantity.  A  month  or  two  later  mucous  patches  are  apt 
to  appear  upon  the  lips,  tongue  or  pharynx,  and  also  about  the  anus.  Sometimes  these  are 
noted  on  the  sides  of  the  scrotum  and  the  under  surface  of  the  penis.  An  acute  iritis  occa 
sionally  occurs  at  this  period. 

All  of  these  symptoms  may  not  be  observed  in  the  same  patient,  but  while  one  suffers 
especially  from  eruptions  upon  the  skin,  another  will  complain  more  of  ulceration  of  the 
mucous  membranes,  of  falling  of  the  hair  or  of  rheumatoid  pains.  The  general  health  of 
the  patient  is  usually  perceptibly  impaired,  although  in  a  majority  of  cases  his  usual  avoca- 
tion is  not  interrupted  to  any  extent.  Before  the  end  of  six  months  or  a  year,  especially  if 
judicious  treatment  has  been  instituted,  the  symptoms  of  the  disease  usually  abate  or  entirely 
disappear.  But  relapses  of  the  various  symptoms  at  lengthened  intervals  are  to  be  expected 
for  at  least  another  year,  although  they  do  not  necessarily  occur.  The  cutaneous  eruptions 
gradually  loose  their  disseminate  and  symmetrical  character  the  farther  they  are  removed 
from  the  date  of  the  initial  lesion,  and  the  other  symptoms  become  less  pronounced  in  char- 
acter. 

During  the  next  few  years,  or  it  may  be  fifteen  or  twenty  years  after  infection,  a  some- 
what different  class  of  lesions  is  commonly  observed.  These  affect  not  only  the  skin  and 
mucous  membranes,  but  the  deeper  connective  tissues,  the  bones  and  the  various  internal 
organs.  These  later  lesions  are  always  localized,  hyperplastic  or  gummatous  in  character, 
and  evince  a  marked  tendency  to  destructive  ulceration.  A  somewhat  arbitrary  distinction 
is  often  made  between  the  secondary  stage  of  syphiUs  in  which  the  lesions  are  superficial  and 
the  tertiary  stage  in  which  the  lesions  are  more  deeply  seated,  but  it  must  be  remembered 
that  superficial  cutaneous  lesions  often  occur  very  late  in  the  course  of  the  disease,  while  in

certain  cases  (galloping  syphilis)  tlie  most  severe  symptoms,  including  affections  of  bones  and 
internal  organs,  are  met  with  a  few  months  after  infection.  StUl  it  is  often  convenient  to 
make  certain  divisions  in  the  conrse  of  syphilis,  and  the  following  stages  or  periods  will 
generally  be  found  to  correspond  to  the  natural  history  of  the  disease. 

1.  Period  of  Inoculation.   From  the  absorption  of  the  virus  to  the  appearance  of  the  chancre. 

2.  Period  of  Imasion,  or '■^  Second  Inoculation.''^     Primary  SypTiilis.     From  the  develop- 

ment of  the  chancre  to  the  outbreak  of  constitutional  symptoms. 

3.  Period  of  Efflorescence.     Secondary  Syphilis.     From  the  appearance  to  the  disappear- 

ance of  symmetrical  eruptions,  and  other  indications  of  blood-poisoning. 

4.  Period  of  Decline.     Tertiary  SypJdlis.     From  the  cessation  of  symmetrical  manifesta- 

tions ad  infinitum. 

For  a  complete  description  of  the  various  eruptions  occurring  in  the  course  of  the  dis- 
ease, the  reader  is  referred  to  the  author's  work  entitled  "Photographic  Illustrations  of  Cu- 
taneous Syphilis." 

Treatment.  In  a  large  proportion  of  cases,  syphilis  will  run  its  course  and  leave  the 
patient  in  a  healthy  condition,  even  though  no  special  treatment  is  instituted.  This  is 
proven  by  the  number  of  men  and  women  in  ordinary  health  who  have  contracted  the  disease 
and  recovered  from  it  without  being  conscious  of  the  fact.  While  a  weak  constitution  and 
habits  of  dissipation  tend  to  aggravate  the  symptoms  of  syphilis  and  predispose  to  certain 
evils  which  are  apt  to  follow  in  the  train  of  the  disease,  a  sound  constitution  and  careful 
attention  to  the  fundamental  laws  of  health  will  enable  most  syphilitic  patients  to  recover  in 
time  without  recourse  to  any  specific  treatment.  Considerable  stress  should  be  laid  upon 
this  point  since  it  is  a  too  prevalent  idea  in  the  professional  mind  that  a  certain  routine  treat- 
ment by  drugs  is  absolutely  essential  in  the  cure  of  this  disease,  and  too  much  reliance  is 
often  placed  upon  the  action  of  certain  specific  remedies.  These  are  of  value  beyond  a  doubt 
but  they  are  not  indispensable. 

The  treatment  of  syphilis  varies  according  to  the  stage  of  the  disease  and  the  character 
of  the  symptoms.  In  most  cases  it  will  be  found  advisable  to  combine  constitutional  and 
topical  remedies. 

In  primary  syphilis  we  have  the  initial  lesion  or  indui'ated  chancre  to  deal  with,  and  the 
question  arises,  "Can  constitutional  infection  be  prevented  at  this  early  stage  of  the  dis- 
ease?" If  the  view  of  Bumstead  and  others  is  held,  viz.,  that  the  initial  lesion  itself  is 
already  an  evidence  of  constitutional  infection,  the  question  must  be  answered  in  the  nega- 
tive. But  if,  on  the  other  hand,  we  accept  the  doctrine  taught  by  Otis  and  others,  viz.,  that 
the  chancre  is  a  local  disease  which  only  infects  the  system  through  the  medium  of  the  lym- 
phatic vessels  after  a  lapse  of  several  weeks,  it  must  be  admitted  that  its  complete  destruc- 
tion at  the  very  outset  and  before  the  nearest  glands  are  involved,  would  save  the  patient 
from  constitiitional  disease.  The  experience  of  many  observers  for  many  years  has  shown 
that  the  most  thorough  cauterization  of  a  hard  chancre  does  not  afford  immunity  from  con- 
stitutional infection.     A  complete  excision  of  the  indurated  mass  on  the  other  hand  has 

(169) 


DISEASES  OF  THE  SKIN— NEOPLASTIC. 

apparently  succeeded  in  a  small  proportion  of  cases  in  affording  this  desired  immunity.  But 
as  the  efficacy  of  this  measure  is  still  an  open  question,  it  cannot  be  recommended,  and 
ouo-ht  not  to  be  attempted  save  in  those  cases  where  an  unmistakable  hard  chancre  is  seated 
upon  a  redundant  prepuce,  in  which  case  circumcision  would  be  advantageous,  even  if  it 
faUed  to  prevent  the  constitutional  manifestations  of  the  disease. 

The  propriety  of  administering  mercury  in  the  primary  stage  of  syphilis  is  another 
point  upon  which  syphilographers  differ.  Since  in  many  cases  there  is  a  doubt  as  to  the 
true  character  of  the  lesion  it  is  often  advisable  to  wait  until  this  important  point  is  settled 
by  the  outbreak  of  constitutional  symptoms.  The  delay  is  never  productive  of  any  serious 
harm,  while  the  administration  of  mercury  at  this  stage  may  prove  unnecessary  in  case  of  a 
doubtful  diagnosis  of  the  lesion.  Moreover,  the  premature  use  of  the  drug  tends  to  i:)Ostpone 
the  evolution  of  the  secondary  symptoms,  modifies  their  character,  so  that  they  are  not 
readUy  recognized,  and  often  leaves  the  patient  in  anxious  doubt  as  to  whether  he  has  really 
had  syphUis  or  not.  This  condition  of  mind  may  interfere  with  matrimonial  prospects,  may 
render  a  nervous  patient  hypochondriacal  and  not  infrequently  prove  worse  than  the  disease 
itself.  The  belief  that  the  administration  of  mercury  at  this  stage  does  harm  I  cannot  ac- 
cept, and  in  a  case  where  there  was  no  possible  doubt  as  to  the  genuineness  of  the  initial 
lesion,  and  where  it  seemed  probable  that  the  patient  would  remain  under  observation  for 
several  years  I  should  advise,  in  the  interest  of  the  patient,  the  early  institution  of  specific 
treatment. 

Topical  applications  in  the  treatment  of  chancre,  i.  e.,  an  indurated  chancre,  are  often 
unnecessary.  The  lesion  is  rarely  productive  of  any  physical  discomfort,  and  may  often  be 
left  to  run  its  coxirse  and  gradually  disappear.  It  ought  never  to  be  cauterized  since  this 
procedure  is  both  painful  and  unprofitable.  Calomel  or  iodoform  may  be  sprinkled  over  the 
surface  if  this  is  abraded  or  ulcerated,  and  the  lesion  should  be  kept  scrupulously  clean. 
The  indui-ation  of  the  chancre  and  neighboring  glands  wiU  often  disappear  more  speedily  if  a 
five  per  cent,  oleate  of  mercury  is  rubbed  into  the  skin,  but  the  result  is  not  always  worth 
the  time  and  trouble. 

In  secondary  syphilis  we  have  to  deal  with  a  group  of  characteristic  symptoms 
which  indicate  a  condition  of  systemic  poisoning.  Active  measures  are  now  usually  de- 
manded by  the  patient,  whatever  the  physician' s  views  may  be  respecting  the  sufficiency  of 
expectant  treatment.  At  this  stage  it  is  advisable  to  adopt  a  combination  of  internal  and 
topical  treatment,  which  experience  has  shown  to  be  of  great  value  in  controlling  the  severity 
and  hastening  the  course  of  the  various  symptoms,  and  in  preventing,  to  a  certain  extent, 
the  subsequent  occurrence  of  undesirable  sequels^.  The  internal  treatment  consists  mainly  in 
the  administration  of  such  remedies  as  are  believed  to  have  a  specific  action  in  the  cure  of 
the  disease,  and  of  these  mercury  has  long  held  a  prominent  position.  The  following  propo- 
sitions embody  the  result  of  my  own  study  and  experience  in  the  use  of  mercury : 

I.  In  the  Medicinal  Treatment  of  Syphilis,  Mercury  is  undoubtedly  our  most  Valuable 
Remedy.    The  beneficial  results  which  follow  the  judicious  employment  of  this  drug  are 

(170)

SYPHILIS. 

sucli  as  to  convince  any  unprejudiced  observer  as  to  its  eminent  virtue.     As,  probably,  no 
reader  will  differ  with  me  on  this  point,  no  argument  is  necessary. 

II.  Mercury  is  an  Overrated  Memedy.  The  fact  that  a  remedy  will  do  much  is  no  indica- 
tion that  it  vdll  accomplish  everything  that  may  be  desired  of  it.  Mercury  will  lessen  the 
manifestations  and  shorten  the  course  of  syphilis  in  most  cases,  but  it  will  not  always  jiro- 
duce  a  speedy  and  beneficial  effegft,  as  many  physicians  have  been  led  to  believe.  Some  of 
the  worst  cases  of  syphilis  which  I  have  observed  in  my  practice  have  ocurred  in  patients 
to  whom  I  gave  mercury  persistently  for  one  or  two  years,  and  I  must  admit  that  in  these 
cases  I  have  faUen  into  the  prevalent  error  of  overestimating  the  curative  action  of  the  drug. 
If  the  profession  generally  were  more  strongly  impressed  with  the  great  value  of  hygienic 
and  tonic  measures  in  the  treatment  of  syphilis,  and  were  less  inclined  to  confide  solely  in 
the  specific  action  of  mercury,  I  am  convinced  that  their  patients  would  receive  a  far  greater 
amount  of  benefit.  We  all  know  that  remedial  agents  of  little  or  no  power  often  acquire  a 
fictitious  value  by  reason  of  the  fact  that  patients  improve  during  their  administration. 
This  post-hoc  fallacy  is  rarely  thought  of  in  connection  with  the  administration  of  mercury 
in  syphilis,  because  we  know  that  the  drug  is  not  inert,  and  have  ample  proof  that  it  can 
and  does  accomplish  a  great  deal ;  but  it  is  well  to  bear  in  mind  that  the  improvement  which 
takes  place  in  our  syphilitic  patients  when  treated  secundum  artem  is  not  wholly  the  effect 
of  the  mercury  which  has  been  administered,  but  is  due  in  great  part  to  the  existence  of 
a  natural  vis  medicatrix. 

III.  Mercury  is  not  Essential  to  the  Cure  of  Syphilis.  This  disease  is  one  which, 
like  the  other  exanthematous  affections,  tends  to  run  its  course.  It  may  be  severe,  and  in 
rare  instances  it  terminates  fatally.  But  in  the  majority  of  cases  of  the  acquired  form  it  is  a 
far  less  malignant  disease  than  it  is  commonly  supposed  to  be,  and  when  the  patient  is  of 
sound  constitution  and  the  infection  is  not  of  unusual  virulence,  it  usually  runs  its  course 
without  producing  any  permanent  damage  to  the  health  of  the  patient.  I  have  treated  for 
two  or  more  years  without  mercury  several  patients  who  expresed  an  objection  to  the  use  of 
the  drug,  and  I  must  say  that  they  apparently  did  as  well  as  other  patients  treated  in  the 
usual  manner.  Some  will  claim  that  these  patients  will  be  very  liable  to  suffer  from  severe 
lesions  in  later  years,  but  of  this  I  have  strong  doubts.  Indeed,  I  have  seen  so  many  hale 
men  of  advanced  years  who  have  certainly  had  syphilis  in  their  younger  days  and  received 
no  specific  treatment,  that  I  cannot  believe  that  a  cure  of  the  disease  is  dependent  upon  the 
use  of  mercury. 

IV.  The  Internal  Admiinistration  of  Mercury  is  preferaMe  to  Inunction.,  Vapor  Baths, 
or  Hypodermic  Injection.  I  am  decidedly  in  favor  of  the  use  of  mercurial  ointments  and 
lotions  for  the  local  treatment  of  cutaneous  symptoms,  but  for  the  cure  of  the  constitutional 
disease  a  somewhat  extended  trial  of  mercurial  inunction  has  led  me  to  abandon  it  as  pos- 
sessing many  objectionable  features  and  few  advantages.  It  is  but  just  for  me  to  say  that 
my  experience  with  vapor  baths  and  hypodermic  injections  has  been  very  limited.  The 
advantages  that  have  been  claimed  for  them,  as  also  for  inunction — viz.,  that  they  do  not 

(171) 


DISEASES  OF  THE  SKIN.— NEOPLASTIC. 

occasion  irritation  of  the  intestinal  tract — are  arguments  in  their  favor  to  those  who  employ 
mercury  internally  in  large  doses  ;  but  they  possess  no  advantage  over  the  method  of  inter- 
nal treatment  which  I  shall  presently  recommend,  and  certainly  cannot  claim  the  merit  of 
simplicity. 

V.  The  Amount  of  Mercury  usually  given  to  SypMlitic  Patients  is  unnecessarily  large. 
From  the  time  when  the  beneficial  effect  of  mercury  was  estimated  by  the  pints  of  saliva 
which  dribbled  from  the  patient's  month,  there  has  been  a  constant  tendency  towards  a  dimi- 
nution in  the  dosage  of  this  drug.  At  the  present  day  it  is  considered  the  proper  thing  to 
give  as  much  mercury  as  the  patient  can  bear  without  showing  symptoms  of  salivation,  and, 
as  nearly  every  writer  on  syphilis  gives  explicit  directions  for  the  treatment  of  salivation,  it 
is  a  just  inference  that  this  undesirable  effect  of  mercury  is  occasionally  met  with  ia  their 
practice.  "While  I  admit  that  certain  patients  are  far  more  liable  to  become  salivated  by 
mercury  than  others,  and  that  in  iritis  and  under  certain  other  conditions  it  may  be  deemed 
advisable  to  "  push"  the  remedy,  I  must  assert  my  belief  that  in  the  vast  majority  of  cases 
of  syphilis  the  very  best  effects  of  mercury  may  be  obtained  by  the  employment  of  doses 
which  will  not  involve  the  slightest  danger  of  salivation. 

There  are  many  patients  who  will  take  a  tablespoonful  of  a  remedy  when  a  teaspoonful 
has  been  prescribed  by  their  physician,  on  the  absurd  principle  that  if  a  small  dose  does 
them  good  a  larger  dose  will  produce  a  corresponding  amount  of  benefit ;  and  there  are  many 
physicians  who  seem  unable  to  disabuse  their  minds  of  the  fallacious  idea  that  within  cer- 
taia  limits  the  curative  effect  of  every  drug  is  in  direct  i-atio  to  the  amount  which  is  adminis- 
tered. I  have  no  faith  whatever  in  the  administration  of  mercury  in  infinitesimal  doses,  but 
my  experience  has  led  me  to  the  belief  that  a  daily  half-grain  or  grain  of  blue  mass,  or  the 
protoiodide  of  mercury  in  divided  doses,  will  do  quite  as  much  if  not  more  good  than  the 
grain  and  a  half  or  two  grains  daily  which  is  the  more  common  dosage. 

VI.  In  the  Internal  Use  of  Mercury  its  Local  Irritant  Effect  should  be  avoided.  This 
can  be  accomplished  by  a  reduction  of  the  size  of  the  dose,  and  its  more  frequent  administra- 
tion if  necessary,  and  by  the  employment  of  milk-sugar  triturations.  Regarding  the  choice 
between  metallic  mercury  and  its  numerous  salts  I  am  not  prepared  to  speak.  My  own  pref- 
erence is  for  the  protoiodide,  which,  given  in  the  form  of  a  trituration  and  in  the  doses  which 
I  have  commended,  will  rarely  be  found  to  occasion  gastric  or  intestinal  disturbance  of  any 
account.  In  the  latter  stage  of  syphilis  I  have  followed  the  custom  of  changing  from  a  mer- 
curous  to  a  mercuric  salt,  from  the  green  iodide  to  the  red  iodide,  e.  g.,  but,  as  the  proto-salts 
are  less  irritant  in  their  local  action,  I  see  no  good  reason  why  the  green  iodide  should  not  be 
continued  throughout  the  course  of  the  disease.  In  my  own  experience  I  have  never  observed 
any  benefit  result  from  a  combination  of  various  salts,  as  recommended  by  Bumstead,  or 
by  a  frequent  change  from  one  preparation  to  another. 

VII.  The  Duraiion  of  Mercurial  Treatment  should  vary  according  to  the  Severity  of 
the  Case.  When  syphilis  began  to  be  described,  at  the  close  of  the  fifteenth  century,  its 
very  worst   forms  were  naturally  observed  and   reported.      The  severest  cases  soon  came 

(172) 


SYPEILIS. 

to  be  regarded  as  a  type  of  the  disease,  and  in  our  text-books  of  the  present  day  the  descrip- 
tion of  syphilis  rarely  corresponds  with  the  average  case  in  practice,  but  is  mainly  a  descrip- 
tion of  the  severer  and  comparatively  uncommon  phase  of  the  disease.  There  are  cases  of 
mild  syphilis,  and  there  are  cases  of  severe  syphUis,  and,  although  I  do  not  coincide  with  M. 
Diday  in  his  opinion  that  mild  syphilis  does  not  demand  mercurial  treatment,  I  do  protest 
against  the  common  practice  of  treating  all  cases  of  syphilis  upon  a  routine  plan.  Who 
would  think  of  venturing  upon  the  unqualified  statement  that  scarlet  fever  should  be  treated 
for  so  many  days  or  weeks  ?  No  one  !  And  yet  we  find  many  writers  on  syphilis  layino- 
down  the  absolute  rule  that  the  disease  must  be  treated  during  a  certain  specified  number  of 
months  or  years,  without  even  hinting  that  for  various  reasons  one  patient  may  not  require 
so  much  treatment  as  another. 

When  I  say  that  there  are  cases  of  scarlet  fever  so  mild  as  to  require  no  treatment,  the 
statement  passes  without  objection ;  but  when  I  hint  that  syphilis  may  occur  in  a  mUd  or 
benignant  form,  I  hear  expressions  of  dissent  on  all  sides.  From  the  text-book  rises  that 
horrible  phantom  of  possible  syphilis,  and  the  awe-stricken  beholder  exclaims,  "  Oh  !  the 
idea  of  applying  the  term  benignant  to  a  disease  which  may  eat  into  the  bones,  cause  paraly- 
sis, blindnsss,  or  sudden  deafness,  or  carry  away  the  nose  of  the  patient ! ' '  The  question  is 
not  whether  the  disease  is  always  benignant,  but  whether  it  is  commonly  benignant.  There 
are  cases  of  syphilis  which  demand  two  years,  or  perhaps  five  years  of  treatment,  but  it 
seems  to  me  to  be  utterly  unreasonable  to  fix  a  certain  time  as  the  duration  of  treatment  for 
all  cases.  When  the  early  symptoms  of  the  disease  are  slight,  and  disappear  speedily  under 
treatment,  I  deem  it  quite  unnecessary  to  continue  the  use  of  mercury  for  two  or  three  years, 
with  an  idea  of  thoroughly  eradicating  the  disease,  and  thus  preventing  subsequent  manifesta- 
tions. The  late  lesions  of  syphilis  may  and  frequently  do  occur  after  a  prolonged  and  thor- 
ough administration  of  mercury.  I  doubt  if  they  are  more  likely  to  apjjear  in  those  cases  in 
which  mercury  is  given  merely  with  a  view  of  removing  the  symptoms  of  the  disease  in  its 
early  stage. 

My  own  practice  is  to  give  mercury  in  every  case  diiring  the  existence  of  any  symptoms 
of  the  diseaae,  whether  it  occurs  early  or  late.  In  the  early  period  I  continue  the  use  of  mer- 
cury for  six  months  after  the  last  symptom  has  yielded,  and  I  do  this  partly  in  deference  to 
the  opinion  of  eminent  authority  and  the  commonly  accepted  teachings.  I  then  stop  the 
administration  of  the  drug  and  await  further  developments.  If  symptoms  reappear,  I  resort 
again  to  the  use  of  mercury,  and  continue  it  this  time  for  two  or  three  months  after  their  dis- 
appearance. In  late  syphilis  I  give  mercury  for  the  purpose  of  subduing  symptoms  which  may 
occur,  and  stop  its  use  as  soon  as  I  have  accomplished  this  result.  In  so  doing,  I  believe  I  am 
practicing  in  accordance  with  the  old  adage  "enough  is  as  good  as  a  feast." 

It  is  a  prevalent  belief  among  authoritative  writers  that  iodide  of  potassium  has  no  actual 
curative  eiiect  in  the  treatment  of  syphilis,  but  merely  the  power  to  cause  the  disappearance 
of  certain  symptoms,  and,  furthermore,  that  it  has  little  or  no  value  in  the  early  stages 
of  the  disease.     I  dislike  to  differ  in  opinion  from  the  weight  of  authority,  particularly  when 

(173) 


DISEASES  OF  THE  SKm— NEOPLASTIC. 

T  have  no  convincing  proof  to  bring  to  the  support  of  my  own  views,  but  I  must  express  my 
belief  that  iodide  of  potassium,  though  inferior  to  mercury,  has  still  a  curative  effect  upon 
syphilis,  and  that  in  the  early  stage  it  is  an  invaluable  therapeutic  agent  in  the  relief  of  cer- 
tain symptoms.  Mercury  in  secondary,  and  iodide  of  potassium  in  tertiary  syphilis,  is  the 
Teaching  and  practice  of  many  physicians.  For  my  part,  I  believe  that  there  is  no  stage  of  the 
disease  when  both  remedies  are  not  calculated  to  do  good.  In  many  cases  of  chancre  charac- 
terized by  a  massive  induration  I  give  iodide  of  potassium,  and  apparently  with  the  effect  of 
reducing  its  size.  In  the  stage  of  eiflorescence  I  must  admit  that  the  drug  has  little  or  no 
effect  upon  the  cutaneous  manifestations.  StiU,  if  it  be  true,  as  has  been  claimed,  that  the 
administration  of  the  drug  causes  an  increase  in  the  number  of  blood  corpuscles,  it  has  the 
same  claim  as  mercury  to  be  ranked  as  a  "tonic  remedy."  In  one  or  two  cases  of  extensive 
mucous  patches,  with  ulceration  of  the  lips  and  tongue,  I  have  seen  a  rapid  disappearance  of 
the  lesion  follow  the  administration  of  iodide  of  potassium  when  mercury  had  been  taken  by 
the  patient  for  several  weeks  with  little  or  no  effect.  But  it  is  in  the  cure  of  the  cephalalgia 
and  arthritic  pains  which  are  so  commonly  associated  with  the  first  outbreak  of  syphilis  that 
iodide  of  potassium  displays  its  remarkable  power,  and  I  am  at  a  loss  to  know  how  these 
symptoms  are  alleviated  by  physicians  who  believe  in  withholding  the  drug  until  the  advent 
of  gummy  tumors  or  late  ulcerations. 

Of  the  great  value  of  the  drug  in  late  syphilis  I  need  not  speak.  I  vaQ.  venture,  how- 
ever, to  remind  the  reader  that  its  power  is  often  exerted  in  a  most  brilliant  manner  when 
its  administration  is  preceded  by  a  short  mercurial  course.  I  can  recall  cases  of  syphi- 
litic orchitis  in  which  the  drug  has  seemed  to  have  very  little  effect.  Mercury  has  been  sub- 
stituted for  it,  and  still  no  marked  change  has  followed.  But,  upon  resuming  the  iodide  of 
potassium  after  the  mercury,  the  swelling  of  the  testicle  has  lessened  with  surprising  rapid- 
ity. In  order  to  ascertain  the  effect  of  either  drug,  I  deem  it  advisable  to  give  mercury  and 
iodide  of  potassium  separately.  It  is  more  instructive  to  the  physician  to  follow  this  plan, 
although  the  "  mixed  treatment "  may  be  equally  beneficial  to  the  patient.  The  iodide  is 
best  prescribed,  I  think,  in  an  aqueous  solution,  a  cubic  centimetre  containing  a  gram,  or  a 
minim  representing  a  grain  of  the  drug. 

Iodide  of  potassium  is  a  remedy  which  no  patient  ought  to  be  compelled  to  take  for  any 
length  of  time.  It  does  its  work  quickly  or  not  at  aU,  and  when  unnecessarily  continued  is 
sure  to  do  harm.  This  is  especially  true  in  those  cases  in  which  immense  doses  are  adminis- 
tered. It  is  undoubtedly  true  that  a  five-gram  dose  will  sometimes  accomplish  a  result 
when  four  grams  would  produce  no  effect,  and  even  larger  doses  may  sometimes  be  re- 
quired ;  but  for  every  case  of  syphilis  which  I  have  seen  benefited  by  immense  doses  of  the 
iodide  I  have  seen  at  least  two  cases  in  which  the  large  doses  have  done  harm.  Several  phy- 
sicians have  told  me  of  cases  of  syphilis  in  which  the  sjTnptoms  were  frightful  to  an  extreme 
degree,  and  could  only  be  kept  in  abeyance  by  the  continued  administration  of  immense 
doses.  I  may  say  here,  what  I  thought  unnecessary  to  say  to  them,  that  my  own  experience 
prevented  my  placing  faith  in  the  correctness  of  their  representations.     I  cannot  believe  that 

(174) 


SYPHILIS. 

there  are  such  cases,  and  I  am  sure  that  in  some  instances  tlie  symptoms  of  lodism  have  been 
mistaken  for  the  effects  of  syphilis.  In  one  or  two  hospitals  I  have  seen  wretched  creatures 
dying  slowly  from  the  combined  effects  of  syphUis  and  heroic  doses  of  potash,  and  have  often 
thought  that,  if  the  amount  of  money  paid  out  for  this  drug  had  been  expended  in  furnish- 
ing a  decent  beef -steak  or  a  little  pure  country  air,  the  chances  for  the  patient's  recovery 
Avould  have  been  vastly  increased.  I  do  not  deny  the  value  of  large  doses  of  the  iodide  of 
potassium  in  certain  cases,  but  I  protest  against  the  continuance  of  such  doses  when  nothing 
but  harm  results. 

Iron  is  a  remedy  which,  in  the  treatment  of  syphUis,  is  of  very  great  value.  Though 
rarely  mentioned  by  syphilographers  as  being  specially  adapted  to  the  treatment  of  this  dis- 
ease, it  deserves,  in  my  opinion,  to  be  ranked  with  mercury  and  iodide  of  potassiiim.  I  wiU 
not  claim  for  it  the  antidotal  or  directly  curative  effect  which  is  usually  ascribed  to  mercury, 
nor  assert  that  it  has  any  marked  influence  upon  the  outward  symptoms  of  the  disease  ;  but 
its  power  to  combat  the  anaemia  which  is  invariably  present  in  the  early  stage  of  syphilis 
renders  it  a  most  valuable  adjunct  to  mercury.  I  usually  prescribe  it  for  patients  presenting 
a  chancre,  or  initial  lesion  of  syphilis,  and  give  it  as  a  routine  remedy  during  the  period  of 
efflorescence,  or  so-caUed  secondary  syphilis.  I  believe  that  it  not  only  elevates  the  tone  of 
the  system,  and  thus  renders  it  more  capable  of  resisting  the  syphilitic  attack,  but  that  it 
also  tends,  in  a  slight  degree  at  least,  to  lessen  the  probability  of  subsequent  manifestations. 
In  the  weakened  state  of  the  system  which  is  so  often  associated  with  late  syphilis,  the  value  of 
iron  is  too  well  known  to  require  even  a  mention,  but  in  the  early  stage  of  the  disease  its  value 
appears  to  be  unknown  or  unappreciated,  and  I  cannot  but  lament  the  prevalent  belief  that 
in  early  syphilis  the  whole  duty  of  the  physician  is  simply  to  give  mercury.  The  tinctui'e 
of  the  chloride  of  iron  is  the  remedy  which  I  usually  employ,  and  I  would  recommend  it, 
not  only  for  its  tonic  effect,  but  for  its  efficacy  in  counteracting  the  slight  diarrhoea  which 
often  results  even  from  very  small  doses  of  mercury.  A  daUy  dose  of  ten  or  fifteen  drops  of 
the  tincture  will  usually  suffice  to  produce  the  latter  result,  and  seems  to  me  to  be  preferable 
to  the  common  custom  of  combining  an  opiate  with  the  merctu'ial. 

Cod-liver  oU  is  a  remedy  which  is  not  unf  requently  of  service  in  the  treatment  of  syphOis. 
When  an  individual  with  a  decidedly  strumous  diathesis  becomes  infected  with  this  disease, 
its  symptoms  are  apt  to  be  severe  and  prolonged,  and  their  amenability  to  the  ordinary  mer- 
curial treatment  is  greatly  lessened.  Indeed,  in  these  scrofulo -syphilitic  subjects  the  adminis- 
tration of  mercury  sometimes  fails  to  produce  a  beneficial  effect,  and  if  pushed  to  any  extent 
is  liable  to  do  harm.  The  use  of  cod-liver  oil,  alone  or  in  connection  with  iodine,  is  more 
likely  to  be  productive  of  good  results  in  these  cases.  It  often  prepares  the  patient  for  a 
systematic  mercurial  treatment,  which  would  not  be  tolerated  if  employed  at  the  very  outset. 
In  late  syphilis,  of  an  ulcerative  type,  I  have  repeatedly  seen  mercury  fail  to  do  good  at  first, 
while  after  the  administration  of  the  oU  for  a  month  or  more  it  has  accomplished  aU  that 
could  be  expected  from  its  use. 

Limited  space  forbids  a  discussion  of  the  hygienic  measixres  which  are  of  value  in  the 

(175) 


DISEASES  OF  THE  SKIN:— NEOPLASTIC. 

treatment  of  syphilis,  but  I  wonld  remind  the  reader  that  in  many  cases  an  over-indulgence  in 
alcoholic  drinks  and  other  habits  of  dissipation,  improper  food,  and  lack  of  out-door  exer- 
cise, hare  produced  a  condition  of  mind  and  body  which  complicates  the  syphilis,  and  for 
which  mercury  is  not  a  specific.  Teachers  of  medicine  strive  to  impress  upon  the  minds  of 
pupils  the  necessity  of  treating  the  disease,  and  not  merely  its  symptoms.  Were  I  able,  I 
would  impress  upon  the  mind  of  every  physician  the  duty  of  treating  the  patient,  and  not 
simply  his  disease.  In  the  use  of  anti-syphilitic  remedies  I  am  certain  that  we  shall  achieve 
the  best  results  if  we  do  not  become  absorbed  -inth  the  idea  that  we  are  treating  a  patient 
with  syphilis,  but  bear  constantly  in  mind  the  important  fact  that  we  are  treating  a  'patient 
with  syphilis. 

LEPRA. 

Synonyms — Mhphan  tiasis   Qrcecorutn. — Zieproty, 

The  leprosy  of  the  present  day,  occurring  in  Oriental  countries  and  elsewhere,  undoubt- 
edly afflicted  the  children  of  Israel  in  the  time  of  Moses.  The  Scriptural  account  of  the  dis- 
ease, however,  as  recorded  in  Leviticus,  is  for  the  most  part  unintelligible,  and  it  is  probable 
that  at  the  time  when  it  was  wi-itten  a  number  of  chronic  and  contagious  affections  were  con- 
founded with  true  leprosy.  In  later  centuries  this  mistake  has  been  repeatedly  made,  and 
the  numerous  leper-houses  established  throughout  Europe  at  the  time  of  the  crusades,  doubt- 
less contained  a  large  proportion  of  syphilitic,  psoriatic  and  other  patients.  In  glancing  at 
the  history  of  leprosy,  we  find  not  only  a  confusion  of  diseases,  but  a  confusion  of  names. 
Suffice  it  to  say  that  the  term  Elephantiasis  Grsecorum  is  now  discarded,  and  the  term  Lepra 
(unfortunately  applied  by  some  writers  to  a  form  of  psoriasis),  is  generally  adopted  in  Ger- 
many, France  and  America  as  the  synonym  of  leprosy. 

True  leprosy  is  now  met  with  not  only  in  distant  parts  of  the  world,  but  also  in  our  own 
country.  Wherever  found  the  disease  presents  the  same  general  characteristics.  In  Egj^pt, 
where  it  doubtless  originated,  and  where  it  has  prevailed  for  several  thousand  years,  it  still 
occurs.  In  Syria,  India,  China  and  Japan,  it  is  quite  common.  In  Europe  it  is  endemic, 
chiefly  along  the  shores  of  the  Mediterranean  and  in  Norway,  although  occasional  cases  are 
met  with  from  time  to  time  in  many  of  the  larger  cities.  In  the  West  Indies  and  portions  ol 
South  America  it  is  also  common,  and  in  the  Sandwich  Islands  it  has  increased  rapidly  in 
recent  years  and  now  affects  a  large  proportion  of  the  native  population.  The  island  of  Mo- 
lokai  has  been  set  apart  as  a  home  for  the  leprous  subjects  of  the  kingdom,  and  several 
thousand  cases  have  been  admitted  to  the  asylum  which  was  founded  there  in  1865.  Coming 
nearer  home,  we  find  the  disease  existing  among  the  Chinese  in  California,  among  the  Nor- 
wegians in  Minnesota,  among  the  French  and  negroes  in  Louisiana,  and  among  certain  French 
Canadians  in  New  Brunswick  and  Nova  Scotia. 

During  the  past  ten  or  fifteen  years  there  have  constantly  been  from  one  to  a  half-dozen 
or  more  cases  of  leprosy  in  the  hospitals  of  New  York  City,  while  other  cases  have  been  re-

l)orted  from  Boston,  Philadelphia,  Baltimore  and  other  cities.  Most  of  these  cases  have 
occurred  among  sailors  or  others,  who  have  spent  considerable  time  in  the  tropical  countrieii 
where  leprosy  is  common  and  there  contracted  the  disease.  In  New  York  there  has  occurred 
but  one  case  in  a  person  who  had  not  been  outside  of  the  State,  and  in  this  case  the  origin  of 
the  disease  could  not  be  explained. 

There  are  three  forms  of  leprosy  based  upon  the  predominance  of  certain  lesions  or 
symptoms,  viz.  :  the  tuberose,  the  macular,  and  the  ancesthetic.  Frequently  both  macules  and 
protuberances  co-exist  in  the  same  patient.  Anaesthesia  in  greater  or  less  degree  is  rarely 
absent  in  advanced  cases,  but  it  may  occur,  as  the  sole  cutaneous  lesion,  neither  macules  nor 
tubercles  being  present.  In  some  text-books  but  two  forms  are  described,  the  macular  and 
the  tubercular. 

Like  syphilis,  lepra  is  a  constitutional  disease,  the  cutaneous  manifestations  of  which, 
though  highly  interesting,  are  of  but  secondary  importance.  A  gradual  decline  in  health 
asuaUy  precedes  the  earliest  characteristic  indications,  which  may  be  faint  brownish  patches 
of  discoloration  or  small  aggregated  tubercles.  In  case  of  tuberose  leprosy  the  first  unmis- 
takable signs  are  usually  seen  upon  the  face.  Tubercular  thickening  invades  the  lower  half 
of  the  forehead,  and  as  the  tubercles  increase  in  size  and  become  tuberous,  the  patient's  face 
assumes  a  very  characteristic  leonine  expression.  The  nose  and  ears  are  very  apt  to  be  the 
seat  of  similar  protuberances. 

The  nerves  undergo  a  remarkable  change  in  lepra,  the  larger  trunks  of  the  extremities, 
as  well  as  the  finer  branches  supplying  the  skin,  becoming  thickened  and  degenerate.  The 
ulnar  nerve,  in  particular,  can  usually  be  felt  enlarged  and  hardened.  The  fingers  and  toes 
and  other  portions  of  skin  supplied  by  these  affected  nerves  suffer  as  a  natural  consequence. 
In  an  early  stage  of  the  disease  they  are  hypersesthetic,  but  as  changes  in  the  nerves  pro- 
gress, they  become  numb  and  almost  lifeless.  Ulcers  form,  which  are  healed  with  difficulty. 
In  severe  cases  the  bones  of  the  extremities  become  carious,  and  one  by  one  the  rotting 
phalanges  fall  off  and  leave  disgusting  stumps.  The  tubercles  upon  the  face  and  elsewhere 
develop  slowly,  and  though  generally  permanent,  they  sometimes  decrease  in  size  and  disap- 
pear by  absorption.  New  ones  in  greater  number  usually  take  their  place,  and  the  disease 
goes  from  bad  to  worse  until  the  strength  of  the  patient  fails. 

It  is  an  extremely  difficult  matter  to  determine  beyond  all  doubt  whether  leprosy  spreads 
only  through  hereditary  transmission  or  only  through  direct  contagion,  or  in  both  of  these 
ways.  The  disease  is  considered  by  many  who  have  had  the  best  opportunities  for  studjing 
it,  to  be  hereditary  in  some  cases,  and  at  the  same  time  capable  of  being  propagated  through 
inoculation. 

The  theory  that  leprosy  may  originate  from  certain  endemic  influences,  such  as  climate, 
diet,  etc. ,  does  not  appear  to  have  a  very  substantial  foundation.  When  the  disease  once 
becomes  prevalent  in  a  community  where  vice,  ignorance  and  filth  abound,  it  usually  tends 
to  increase,  but  it  is  far  from  being  a  highly  contagious  disease,  as  is  commonly  imagined. 
Physicians  and  hospital  nurses  need  have  no  hesitancy  in  caring  for  leprous  patients,  pro- 

(177) 


DISEASES  OF  THE  SKIN.— NEOPLASTIC. 

vided  the  ordinary  precautions  are  taken  which  are  usual  in  the  treatment  of  syphilitic  pa- 
tients. The  fear  of  the  disease  ever  spreading  through  an  intelligent  community  appears  to 
me  to  be  without  foundation. 

The  opinion  that  leprosy  results  from  a  germ  or  parasite  to  be  found  by  careful  micro- 
scopical examination  in  the  affected  tissues  is  one  which  is  now  held  by  many  eminent 
authorities.  This  germ  is  kno^vn  as  the  "bacillus  leprae."  The  rod-like  micro-organisms 
are  found  in  the  cells  of  a  leprous  neoplasm  but  not  in  the  blood  of  leprous  patients. 

Diagnosis.  The  diagnosis  of  a  case  of  leprosy  is  more  or  less  easy,  according  as  the 
disease  is  more  or  less  developed.  In  an  advanced  stage,  its  peculiar  features  proclaim  the 
diagnosis  at  a  glance,  but  in  its  incipiency  it  may  pass  unsuspected  for  months  or  years, 
especially  when  met  with  in  a  country  or  region  where  it  does  not  prevail.  The  earliest 
symptoms  are  usually  a  gradual  loss  of  strength  from  no  apparent  cause,  chillj'  sensations, 
vague  pains,  and  numbness  of  the  extremities.  Later  the  disease  is  characterized  by  the  de- 
velopment of  numerous  brownish  patches  upon  the  extremities,  nodules  above  the  eyebrows 
or  about  the  ears,  and  tracts  of  anaesthetic  skin  particularly  on  the  hands  and  feet.  The 
diseases  \vith  which  leprosy  might  be  most  readily  confounded  are  syphilis,  lupus,  leuco- 
derma,  scleroderma  and  morphoea ;  but  the  features  of  a  case,  if  at  all  well  marked,  will 
usually  proclaim  its  nature  as  soon  as  the  diagnosis  of  leprosy  is  suggested. 

Lepra  tuberosa  may  bear  a  resemblance,  at  first  glance,  to  tubercular  syphilis,  the  fore- 
head being  a  favorite  seat  of  either  disease.  But  the  infiltration  of  the  skin  in  leprosy  is 
more  diffused,  the  protuberances  are  of  variable  size,  often  larger  in  the  center  of  the  patch, 
and  always  of  a  dull,  bronzed  hue.  The  syphiloderm  in  this  locality  presents  small,  hard 
tubercles  of  a  brownish-red  color,  arranged  often  in  a  circular  or  crescentic  form,  tending  to 
ulceration  and  sometimes  enclosing  a  smooth  area.  Lepra  maculosa  may  simulate  leuco- 
denna,  both  in  form  and  color,  but  the  patches  in  the  former  are  never  perfectly  smooth  as 
in  the  latter  affection. 

Treatment.  Leprosy  is  a  disease  which  is  commonly  regarded  as  practically  incurable, 
since  there  is  no  remedy  or  plan  of  treatment  which  can  be  adopted  with  the  certainty  of 
restoring  the  patient  to  perfect  health.  And  yet  many  cases  improve  to  a  greater  or  less 
extent  under  treatment,  and  some  have  been  reported  in  which  an  apparent  cure  of  the  dis- 
ease has  been  effected.  My  own  experience  in  the  treatment  of  this  disease,  though  a  com- 
paratively limited  one,  has  convinced  me  that  judicious  measures  will  ameliorate  the  condi- 
tion of  the  patient  in  a  marked  degree,  and  I  am  by  no  means  disposed  to  admit  that  the 
disease  is  an  incurable  one. 

The  first  step  in  the  treatment  of  leprosy  is  to  remove  the  patient,  if  possible,  from  the 
locality  in  which  the  disease  has  been  contracted.  Hutchinson  has  reported  the  case  of  a 
woman  whose  parents  had  always  resided  in  England,  and  who  contracted  the  disease  in  a 
severe  form  during  a  twelve  years  sojourn  in  Jamaica.  She  became  apparently  free  from  all 
symptoms  after  her  return  to  England,  and  during  a  period  of  twenty  years  there  was  no 
return  of  the  disease,  and  the  woman  considered  herself  perfectly  well.     A  mere  change  of

residence  could  not  be  expected  to  effect  a  cure,  since  leprosy  is  known  to  run  its  course  to  a 
fatal  termination  in  almost  every  climate ;  but  a  change  of  diet  and  habits  is  doubtless  a  fac- 
tor of  far  greater  importance.  In  this  case  Hutchinson  attributed  the  cure  mainly  to  a  ces- 
sation of  a  diet  composed  largely  of  unwholesome  fish,  which  in  leprous  countries  is  supposed 
by  many  to  be  an  active  cause  of  the  disease.  The  next  step  is  to  place  the  patient  under 
the  best  hygienic  conditions,  and  to  treat  the  symptoms  of  the  disease  on  general  principles. 
Where  ulceration  of  the  extremities  has  taken  place,  the  sores  should  be  kept  scrupulously 
clean,  and  dressed  with  some  slightly  stimulating  application,  such  as  balsam  of  Peru.  For 
the  pain,  which  is  usually  annoying  in  an  advanced  stage  of  the  disease,  morphia  may  be 
given.  Stretching  of  the  ulnar  nerve  under  ansesthesia  has  been  resorted  to  in  some  cases  of 
leprosy,  with  a  view  to  restore  its  functions.  The  operation  seems  to  have  i)roduced  at  least 
a  temporary  benefit  in  a  considerable  number  of  cases.  The  thickening  of  the  nerve  has 
been  lessened,  and  the  anaesthetic  portions  of  the  skin  supplied  by  it  have  been  restored  to 
sensibility.  As  regards  internal  treatment,  many  remedies  have  been  vaunted,  but  as  yet  no 
specific  has  been  found.  There  are  certain  balsams  and  oils,  which,  if  used  for  a  length  of 
time,  produce  a  favorable  change  in  the  condition  of  the  patient,  though  it  cannot  be  said 
that  they  will  always  cure  the  disease.  Chief  among  these  are  gurjon  balsam  and  cashew 
and  chaulmoogra  oils.  The  former  is  used  by  British  surgeons  in  India  and  other  tropical 
localities,  with  good  results.  For  internal  use,  an  emulsion  is  made  of  equal  parts  of  the 
oil  and  lime  water,  and  administered  in  half-ounce  doses,  twice  daily.  As  an  external  appli- 
cation, the  oil  is  mixed  with  three  parts  of  lime-water,  and  with  this  the  whole  body  is 
thoroughly  rubbed.  Under  this  plan  of  treatment  patients  in  an  advanced  stage  of  leprosy 
imijrove  in  health,  the  ulcers  heal,  the  tubercles  soften  and  disappear,  and  the  ansestheiic 
parts  resume  their  sensibility. 

Chaulmoogra  oil  (expressed  from  the  seeds  of  gynocardia  odorata)  appears  to  be  the  most 
efficient  remedy  which  has  been  used  in  the  treatment  of  leprosy,  although  it  has  seemed  to 
have  little  or  no  effect  in  certain  cases.  One  patient  with  macular  leprosy  who  was  under  my 
care  for  about  a  year  improved  steadily  under  daily  drachm  doses  of  the  oil.  The  brownish 
patches  upon  face  and  trunk  entirely  disappeared,  his  general  health  improved,  and  at  last, 
report  he  claimed  to  be  entirely  free  from  all  evidence  of  the  disease,  save  the  contraction 
and  numbness  of  the  fingers.  One  case  of  macular  leprosy  in  a  boy  of  nine,  which  I  had  the 
repeated  opportunity  of  seeing,  manifested  a  considerable  degree  of  improvement  under  an 
ordinary  anti-syphilitic  course  of  treatment. 

The  prognosis  of  leprosy,  as  is  evident  from  the  foregoing,  is  unfavorable.  In  the  tuber- 
cular, which  is  the  most  grave  form,  death  is  usually  expected  to  take  place  within  three  to 
nine  years  after  the  first  symptoms  of  the  disease  are  noted.  Very  frequently  pysemia  sets  in, 
and  carries  of  the  patient  with  unexpected  suddenness.  The  macular  or  the  anaesthetic  form 
of  the  disease  may  develop  gradually,  and  exist  for  a  long  time  without  any  marked  impair- 
ment of  the  patient's  health.  Twenty- four  years  has  been  fixed  as  the  extreme  limit  of  the 
disease  by  physicians  who  have  had  the  opportunity  of  observing  it  where  it  is  endemic.

DISEASES  OF  THE  SKm.— NEOPLASTIC. 


RHINOSCLEROMA. 

Rhinoscleroma  is  a  rare  disease  which  has  been  observed  in  Europe,  but  not,  as  far  as  I 
am  aware,  in  this  country.  The  essential  features  of  the  disease,  as  the  name  implies,  con- 
sists in  an  induration  of  the  nose.  This  induration  begins  in  the  form  of  flattened  nodules 
or  circumscribed  patches  which  are  usually  seated  at  the  anterior  nares.  They  are  smooth^ 
of  normal  color  or  of  a  brownish  hue  and  sensitive  to  pressure.  They  gradually  increase  in 
size,  and  involve  both  the  mucous  membrane  and  the  skin  of  the  nose  and  a  portion  of  the 
upper  lip.  In  time  the  nose  becomes  transformed  into  a  hard,  rigid  and  flattened  mass  of 
tissue,  the  nasal  passages  being  diminished  in  size  or  completely  obstructed.  The  gro^\^h 
exhibits  no  tendency  to  softening  or  ulceration,  although  fissures  may  form  at  the  base  of  the 
alse  nasi,  and  become  covered  with  a  crust. 

The  cause  of  the  disease  is  unknown.  Its  course  is  a  chronic  one  and  apparently  inde- 
pendent of  any  constitutional  condition.  The  unsightly  deformity  which  the  growth  pro- 
duces and  the  impeded  respiration  are  the  only  symptoms  of  which  the  patient  is  likely  to 
fiomplain. 

Treatment.  The  disease  will  not  yield  to  any  treatment  short  of  cauterization  or  partial 
excision,  and  even  this  plan  has  usually  been  followed  by  a  subsequent  return  of  the  growth 
to  its  former  condition. 

EPITHELIOMA- 

Synonym — Skin  (lancer. 

The  term  cancer  implies  a  malignant  growth  which  tends  to  invade  and  destroy  certain 
tissues  (notably  the  cutaneous  and  glandular),  which  is  prone  to  recur  after  excision,  and 
which  induces  a  peculiar  diathetic  condition  frequently  ending  in  death.  Epithelioma  is  one 
of  tlie  least  malignant  forms  of  cancer,  and  develops  primarily  on  a  cutaneous  or  mucous 
surface. 

Like  other  affections  of  the  skin,  epithelioma  presents  a  variable  appearance  in  different 
subjects,  in  different  parts  of  the  body  and  at  different  stages  of  its  growth.  Four  clinical 
forms  may  be  described,  viz. ,  a  supei-ficial,  a  rodent,  a  deep-seated  and  a  papillomatous  form. 
These  forms  or  phases  may  present  themselves  in  a  single  case  as  successive  stages  in  the  pro- 
gress of  the  disease. 

The  sup«rficial  form  appears  at  first  as  a  small,  roundish,  slightly  elevated  patch  of  col- 
orless infiltration.  It  may  remain  in  this  condition  for  three  or  four  years,  scarcely  noticed 
by  the  patient.  Slowly  one  or  more  flattened  papules  of  a  yellowish-white  or  waxy  hue  are 
developed,  forming  a  rather  prominent  and  dense  growth,  usually  of  circular  or  oval  .form. 
Arriving  at  the  size  of  a  three  or  five-cent  piece  the  central  portion  becomes  depressed,  while 
the  border  lemains  smooth  and  glossy  or  assumes  a  nodular  aspect.  Frequently  the  growth 
is  composed  of  three  or  four  nodules  grouped  so  as  to  resemble  the  crown  of  a  molar  toof  h.

with  fine  blood-vessels  running  between  them,  and  ramifying  in  the  central  depression. 
When  superficial  ulceration  develops  a  thin  scab  in  this  central  pit,  the  growth  bears  some 
resemblance  in  form  and  appearance  to  a  well-developed  vaccine  vesicle. 

The  rodent  form,  i.  e.,  a  rodent  ulcer,  may  begin,  as  has  been  intimated,  in  the  center  of 
the  superficial,  button-like  epithelioma,  and,  by  extending  in  depth  and  circumference,  grad- 
ually convert  this  into  a  circular,  polygonal  or  irregular  ulcer  with  a  sharp-cut  border,  an 
elevated,  indurated  and  flattened  margin,  and  a  clean  glazed  surface.  By  the  growth  of  dense 
waxy  nodules  at  the  periphery,  and  the  necrosis  of  the  inner  surface  of  the  wall,  this  ulcer 
increases  in  size,  and  in  a  few  years  becomes  as  large  as  a  silver  dollar  or  larger.  It  is  re- 
markably slow  in  its  growth,  and  may  exist  for  fifteen  or  twenty  years  without  affecting  the 
general  health  of  the  patient,  or  involving  the  neighboring  lymphatic  glands.  The  rodent 
epithelioma  often  originates  in  an  insignificant  "  pimple"  or  "wart,"  which  becomes 
scratched  or  injured,  and  forms  a  blackish  scab.  This,  when  removed,  discovers  a  small 
ulcer  of  trifling  appearance,  but  which  shows  little  tendency  to  heal.  If,  under  treatment,  it 
cicatrizes,  it  is  only  to  break  out  again  and  to  form  a  larger  sore.  This  ulcer  may  be  annular, 
and  inclose  an  island  of  cicatricial  tissue,  or  crescentic  in  form,  or  serpiginous  in  its  charac- 
ter, creeping  over  the  surface  and  leaving  a  superficial  scar  in  its  track.  The  induration  is  so 
superficial  as  not  to  be  always  readily  distinguishable,  destruction  of  tissue  seeming  to  keep 
pace  with  the  new  growth. 

The  deep-seated  or  infiltrating  form  of  epithelioma  may  follow  the  superficial  or  rodent 
form,  and  its  clinical  features  will  depend  upon  its  location.  When  the  eyelid  is  attacked 
the  disease  usually  begins  as  a  superficial  nodule.  In  a  few  years  or  sooner  the  whole  palpe 
bral  opening  becomes  affected,  and  the  disease  assumes  a  rodent  form.  Destructive  ulcera- 
tion may  now  attack  the  conjunctiva  and  quickly  destroy  both  lids  and  eye.  Indeed,  the 
disease  often  progresses  in  depth,  attacks  the  bones  of  the  orbit,  and  produces  a  most  fright- 
ful cavity.  A  similar  destructive  process  sometimes  ensues  when  the  disease  is  situated  near 
the  nasal  orifice  or  the  oral  commissure.  When  the  infiltrating  form  begins  as  such,  which  is 
usually  the  case  upon  the  lower  lij),  there  is  developed  a  hard  tumor  of  pea  or  marble  size, 
slightly  elevated  above  the  surface.  It  is  at  first  movable,  but  later  adheres  to  the  subjacent 
tissues.  This  tumor  is  almost  invariably  single,  and  eventually  becomes  an  ulcer,  through 
t\ecrosis  of  the  central  portion  of  the  mass  and  the  formation  of  an  abscess.  It  usually  runs 
a  more  rapid  course  than  the  rodent  ulcer,  and  differs  from  this  form  of  epithelioma  chiefly 
in  its  tendency  to  imi^licate  adjacent  glands.  The  papillomatous  form  is  uncommon,  and 
may  be  regarded  as  a  peculiar  warty  development  of  the  superficial  or  rodent  form.  • 

Epithelioma  usually  attacks  the  face,  thirty  per  cent,  of  aU  cases  appearing  upon  the  Up. 
It  occasionally  occurs  upon  the  genitals,  particularly  in  the  male,  and  may  occur  elsewhere. 
The  supei-ficial  or  rodent  form  occurs  usually  about  the  eyes  and  nose,  while  the  favorite  seat 
of  the  infiltrating  form  is  the  lower  lip.  On  the  scrotum  the  growth  is  at  first  superficial, 
but  soon  progresses  in  depth.  On  the  glans  penis,  and  especially  the  coronal  portion,  the 
superficial  or  papillomatous  form  is  most  apt  to  occur,  frequently  with  swelling  and  indura-

DISEASES  OF  THE  SKIN— NEOPLASTIC. 

tion  of  tlie  lympliatic  vessels  of  tlie  dorsum  penis.  Epitlielioma  usually  occurs  in  patients 
over  lifty,  but  it  may  occur  before  that  age.  Seventy-five  per  cent,  of  cases  occur  in  males. 
In  old  persons  subject  to  epithelioma,  a  peculiar  atrophic  whiteness  of  the  skin  over  the  tem- 
ples is  sometimes  observed,  \vith  various  indications  of  degeneration,  such  as  numerous  small 
specks  of  xanthelasma  and  patches  of  seborrhoea  covered  by  horny  and  blackened  scales 
The  etiology  of  the  disease  is  obscure,  and  in  most  cases  neither  patient  nor  physician  can 
ossio-n  any  reasonable  cause  for  its  development.  In  a  small  percentage  of  cases  a  family 
history  of  cancer  can  be  traced.  Local  irritation  undoubtedly  acts  as  a  predisposing  causes 
but  its  influence  has  been  overrated.  For  instance,  the  term  smoKer  s  cancer  has  been  used 
as  a  synonym  for  epithelioma  of  the  lip,  and  where  a  patient,  as  is  frequently  found  to  be 
the  case  has  for  years  performed  Ms  daily  labor  with  pipe  in  mouth,  the  name  might  seem  to 
be  warranted.  But  other  men  smoke  constantly  at  their  work  and  do  not  have  epithelioma, 
while  the  disease  frequently  attacks  women,  and  men  who  never  smoke.  In  like  manner  the 
chimney-sweeper" s  cancer,  or  epithelioma  of  the  scrotum,  occurs  in  countries  where  the  con- 
struction of  houses  is  such  as  to  furnish  no  occupation  for  this  class  of  laborers. 

TuEATiiENT.  The  treatment  of  epithelioma  usually  demands  prompt  and  active  meas- 
m-es.  When  the  di-sease  is  evidently  increasing  in  extent  by  involving  adjacent  tissue,  there 
should  be  no  temporizing.  The  earlier  the  patch  can  be  destroyed  the  better,  and  it  is  as  well 
to  destroy  the  healthy  skin  at  the  margin  of  a  small  patch  as  to  allow  the  disease  to  invade 
and  destroy  it.  When  progress  is  very  rapid,  the  immediate  removal  of  the  diseased  part, 
or  its  complete  destruction  by  means  of  a  powerful  caustic,  is  the  only  treatment  worthy  of 
being  considered.  As  to  value  of  tonics,  good  food  and  fresh  air,  I  need  not  speak  as  no  one 
will  doubt  their  indii-ect  influence  in  lessening  the  spread  of  the  disease,  and  in  augmenting 
the  beneficial  effects  of  an  operation.  But  while  internal  treatment  may  be  advantageously 
employed  to  put  the  patient  in  the  best  possible  condition  before  attempting  to  remove  the 
growth,  no  time  should  be  lost  in  the  endeavor  to  eradicate  it  by  internal  medication  when- 
ever it  evinces  a  disposition  toward  active  growth.  The  question  as  to  whether  internal 
medication  can  possibly  have  a  direct  effect  upon  the  growth  of  epithelioma  is  sub  jxuHce. 
Although  the  results  following  the  use  of  most  of  the  anti- cancerous  remedies  which  have 
enjoyed  a  widespread  though  transient  reputation,  are  either  disappointing  or  delusive,  '  t  by 
no  means  foUows  that  a  specific  remedy,  or  one  acting  as  decidedly  as  does  quinine  in  inter- 
mittent fever,  may  not  exist.  The  majority  of  writers  agree  in  rejecting  the  idea  that  any 
dii-ect  influence  can  be  exerted  on  epithelioma  by  the  use  of  internal  remedies.  A  certain 
number  of  experienced  physicians  claim,  on  the  other  hand,  that  the  disease  is  amenable  to 
internal  treatment.  Neligan,  who  describes  the  rodent  form  of  epithelioma  under  the  head 
of  lupus  deoorans,  lays  stress  upon  the  importance  of  administering  iodine,  iodide  of  potas- 
sium and  cod-liver  oil  in  small  doses  continued  for  a  length  of  time.  He  regards  the  employ 
;nent  of  topical  agents  as  auxiliary  to  the  constitutional  treatment,  which  he  claims  should 
engage  the  chief  attention  of  the  physician.  I  have  not  such  confidence  in  the  efficacy  of 
these  drugs,  but  in  cases  where  the  patient  objects  to  the  use  of  the  knife  or  cautery,  I  -/ronld

advise  the  administration  of  tlie  remedies  mentioned,  or  preferably  arsenic,  in  small  and  long- 
continued  doses.  Fowler's  solution  might  be  advantageously  used  both  internally  and  exter- 
nally, since  in  some  cases  of  epithelioma  with  slight  ulceration,  healing  has  been  observed  to 
follow  a  daily  penciling  of  the  sore  with  ten  to  twenty  drops  of  the  solution  (Anderson). 

In  the  use  of  caustics  in  epithelioma  failure  and  even  harm  often  results  from  an  insuffi- 
cient application  of  the  caustic,  through  fear  of  going  too  deeply,  or  occasioning  too  much 
pain.  The  growth,  instead  of  being  totally  destroyed,  merely  becomes  inflamed,  and  is  stim- 
ulated to  a  further  increase  in  extent.  As  a  rule  the  burning  must  be  thoroughly  done  or  not 
at,  all.  The  choice  between  the  knife  and  caustic  depends  upon  the  extent,  location  and  char- 
acter of  the  growth,  when  there  is  no  whim  or  prejudice  on  the  part  of  the  patient.  When 
the  growth  is  large,  it  is  usually  advisable  to  scrape  or  excise  as  thoroughly  as  possible,  and 
to  apply  the  deliquesced  chloride  of  zinc  to  the  raw  surface,  especially  when  fears  are  enter- 
tained of  a  recurrence  of  the  disease.  When  the  growth  is  superficial,  one  or  two  applica 
tions  of  a  caustic  paste  will  answer  the  purpose.  Hebra's  arsenical  paste  (arsenious  acid,  one 
pai-t,  red  sulphuret  of  mercury,  three  parts,  and  cold  cream,  twenty-four  parts),  though  a 
painful  application,  acts  merely  upon  the  diseased  tissue,  sparing  the  healthy  skin.  It  should 
be  applied  on  a  piece  of  linen,  and  allowed  to  remain  twenty-four  hours,  being  renewed  if 
necessary.  Marsden's  paste  is  prepared  as  follows  :  To  equal  parts  of  arsenious  acid  and 
powdered  acacia  add  sufficient  water  to  moisten  and  make  a  thick  paste.  This  is  to  be  spread 
over  the  cleansed  surface  of  the  part  to  be  destroyed,  and  covered  with  absorbent  cotton.  A 
slough  forms,  dries,  and  falls  in  a  week  or  more.  As  a  rule,  the  best  caustic  is  the  one  with 
which  the  operator  is  most  familiar.  I  prefer  the  caustic  potassa,  either  solid  or  liquefied. 
This  forms  a  blackish  slough,  small  or  large,  as  is  desired.  Its  action  can  be  readily  checked 
by  applying  vinegar  or  dilute  acetic  acid.  The  pain  resulting  is  not  very  severe,  and  quicklj 
ceases,  having  this  great  advantage  over  the  arsenical  paste.  An  ointment  of  pyrogallic  acid 
(20  per  cent. )  applied  as  a  paste  has  recently  been  highly  recommended. 

The  removal  of  an  extensive  ex)ithelioma,  occurring  upon  the  lip  or  elsewhere,  frequentlj 
involves  a  plastic  operation  to  restore  the  lost  parts.  In  such  cases  the  knife  is  far  prefera- 
ble to  caustics,  as  the  removal  of  the  disease  and  the  restoration  of  the  part  can  be  combined 
in  one  operation. 

SARCOMA. 

Sarcoma  is  a  malignant  growth  which  commonly  involves  the  lymphatic  glands  primarilj-, 
and  only  appears  upon  the  surface  of  the  skin  as  a  metastatic  form  of  the  disease.  In  cer- 
tain cases,  however,  it  has  been  observed  as  an  idiopathic  cutaneous  affection.  In  these  cases 
a  number  of  small  tumors  varying  in  size  from  a  pea  to  a  marble,  make  their  appearance 
upon  various  portions  of  the  body.  They  are  at  first  discrete,  of  a  tolerably  firm  consistence, 
and  present  a  smooth,  raised  surface.  In  time  they  become  larger  and  flatter,  and  the  cen- 
tral portion  is  more  or  less  depressed.  When  two  or  more  develop  in  close  proximity  to  one 
another,  they  often  manifest  a  tendency  to  coalesce. 

(183) 


DISEASES  OF  THE  SKIN.— NEOPLASTIC. 

As  the  name  implies,  sarcoma  constitutes  a  fleshy  tumor,  and  microscopic  examination 
Khows  that  it  is  composed  of  cellular  tissue  of  an  embryonic  character.  Various  foi-ms  of 
sarcoma  are  described  by  pathologists,  but  there  are  three  forms  which  are  most  apt  to  involve 
the  skin     These  are  known  as  the  round  cell,  the  spindle  cell  and  the  melanotic  sarcomata. 

The  round  cell  sarcoma  is  made  up  of  small  round  or  oval  cells,  usually  no  larger  than 
the  white  blood  corpuscles.  It  commonly  forms  a  soft  tumor  which  is  apt  to  be  discolored 
as  the  result  of  interstitial  hemorrhage.  In  certain  cases  the  cells  are  packed  in  masses  sepa- 
rated by  a  c(>nnective  tissue  stroma,  forming  the  variety  kno^vn  as  alveolar  sarcoma. 

The  spii'.dle  cell  sarcoma  is  made  up  of  bundles  of  spindle-shaped  cells,  which  interlace 
and  form  a  1  umor  which  is  usually  much  firmer  than  the  round  cell  sarcoma.  It  is  not  as 
likely  as  the  other  forms  to  be  followed  by  secondary  tumors  in  the  internal  organs. 

The  melanotic  sarcoma,  which  is  the  most  common  of  these  three  forms,  is  made  up  of 
cells  which  are  usually  spindle-shai^ed,  and  contain  more  or  less  brown  or  blackish  pigment. 
It  always  develops  in  the  pigmented  layer  of  the  eye  or  skin,  and  is  very  apt  to  appear  pri- 
marily on  the  site  of  a  pigmented  mole.  It  exhibits  a  marked  tendency  to  metastasis,  and 
numerous  tumors  of  varying  size  are  soon  formed  not  only  in  other  portions  of  the  skin,  but 
also  in  ihn  internal  organs. 

DiAONOsis.  The  diagnosis  of  sarcoma  occurring  in  a  multiple  form  is  usually  easy.  A 
solitary  tumor  in  the  absence  of  pigmentation  and  ulceration  might  be  mistaken  for  a  syphi- 
litic gumma,  but  the  firmness  of  the  latter  gro\vth  and  the  history  or  coincident  symptoms 
of  syphilis  w  ould  usually  reveal  its  nature.  A  single  ulcerated  sarcoma  may  be  recognized 
by  its  marked  tendency  to  bleed  upon  the  slightest  provocation. 

Tkeatjiext.  a  solitary  sarcoma  may  be  excised  or  destroyed  by  means  of  the  galvano- 
cautery,  ample  precautions  having  been  taken  to  control  the  hemorrhage  which  is  often  ex- 
cessive. Th«  disease  is  likely  to  return  in  situ,  or  to  manifest  itself  in  some  other  part.  In 
multiple  sarcoma  curative  measures  are  scarcely  to  be  hoped  for,  and  usually  the  fatal  termi- 
aation  can  only  be  delayed  by  treatment. 

Kobner,  however,  has  reported  a  case  of  general  sarcoma  cured  by  the  subcutaneous 
injection  of  arsenic.  The  patient  was  a  girl  eight  and-a-half  years  old,  who  presented  nu- 
merous small,  hard,  brownish-red  nodules  on  the  face  and  both  upper  and  lower  extremities. 
The  treatment  lasted  a  year  or  more,  and  resulted  in  the  complete  disappearance  of  the  small 
tumors,  which  microscopical  examination  had  shown  to  be  the  unmistakable  products  of  a 
genuino  spindle-ceUed  sarcoma  of  the  skin  and  subcutaneous  tissue.

CHAPTER  VII. 

NEUROTIC  DISEASES. 

The  part  which  the  nerves  of  the  skin  play  in  the  production  of  cutaneous  disease  is  a 
very  important  one.  Inasmuch  as  the  nutrition  of  the  skin  and  its  functional  activity  are 
dependent  upon  nervous  inHuence,  the  prime  factor  in  the  etiology  of  many  skin  affections 
may  be  sought  and  found  in  an  impaired  condition  of  the  nervous  system.  Many  other 
affections  are  greatly  aggravated,  if  indeed  they  are  not  caused  by  irritation  reflected  from 
internal  organs,  and  hence  it  may  be  safely  asserted  that  a  neurotic  element  of  greater  or  less 
importance  may  be  shown  to  exist  in  the  majority  of  diseases  of  the  skin.  In  some  an  actual 
lesion  of  the  brain  or  nerve  trunk  has  been  demonstrated,  but  the  clinical  appearances  of 
such  affections  have  led  to  their  association  with  other  classes.  In  the  present  class  are 
included  merely  those  cases  in  which  there  is  an  abnormal  sensibility  of  the  skin,  with  no 
special  lesions  of  an  inflammatory  or  other  character.  This  abnormal  sensibility  may  be 
classed  as  hyperaesthesia,  anaesthesia  or  parsesthesia.  Under  the  latter  head  are  included  two 
affections  in  which  the  functional  disturbance  of  the  nerves  is  one  of  quality  rather  than  of 
quantity.     These  are  pruritus  and  dermatalgia. 

An  extreme  sensibility  of  the  skin  is  not  unfrequently  met  with  in  connection  with  gen- 
eral nervous  derangement,  and  in  certain  rare  cases  it  may  be  met  with  alone,  The  whole 
surface  or  but  a  limited  portion  of  the  skin  may  be  affected,  and  the  slightest  external  irrita- 
tion may  suffice  to  produce  vasomotor  disturbance  with  various  subjective  sensations.  The 
hyperaesthesia  in  one  case  may  be  readily  excited  by  friction  of  clothing,  whUe  in  others  it 
is  more  likely  to  be  the  result  of  heat  or  cold.  A  complete  or  partial  loss  of  sensibUity  of 
the  skin  is  often  observed  in  the  case  of  hysterical  females,  without  any  cutaneous  lesions- 
In  a  few  skin  diseases,  and  notably  leprosy,  anaesthesia  may  be  a  prominent  feature  of  the 
affected  parts. 

PRURITUS. 

Pruritus,  or  "itching,"  is  usually  a  symptom  rather  than  a  disease,  but  to  very  many 
cases  in  which  there  is  an  intense  itching  of  the  skin,  evidently  of  internal  origin,  the  term 
"  Pruritus  cutaneus  "  is  conveniently  applied.  The  itching,  which  is  associated  with  eczema, 
scabies  and  certain  other  pruriginous  skin  affections,  is  not  included  in  the  present  disease, 
which  is  whoUy  independent  of  any  structural  alteration  of  the  skin.  The  affection,  thus 
limited,  is  usually  a  chronic  one  and  may  involve  the  whole  skin  or  be  limited  to  a  particular 
region,  such  as  the  anus,  scrotum  or  vulva.     The  sensation  experienced  by  the  patient  is 

(186) 


DISEASES  OF  THE  SKIN—NEUBOTIC. 

variously  described  as  prickling,  crawling  or  burning.  It  is  very  annoying  even  when  slight, 
and  in  its  most  pronounced  form  is  capable  of  destroying  all  sense  of  comfort  and  sometimes 
driving  the  unfortunate  sufferer  to  the  verge  of  suicide.  During  the  day  the  itching  may  be 
comparatively  slight  and  only  troublesome  when  the  patient  is  overheated  or  excited.  At 
night,  however,  severe  exacerbations  occur  and  often  many  sleepless  hours  axe  devoted  to 
i  neffectual  attempts  to  quell  the  torment  by  constant  scratching. 

In  the  worst  cases  of  pruritus  an  impairment  of  the  general  health  is  always  noticeable. 
This  may  be  considered  as  partly  the  cause  of  the  affection  and  partly  the  result  of  the  in- 
tense suffering  which  the  patient  is  forced  to  undergo.  Many  causes  of  the  affection  have 
been  discovered  by  the  careful  study  of  cases,  but  nevertheless  its  etiology  is  frequently 
obscure.  Hepatic  and  renal  disease  frequently  give  rise  to  itching  of  the  skin.  In  jaundice 
it  is  observed  in  a  large  proportion  of  cases  at  the  outset  of  the  attack  or  even  some  time 
before,  and  probably  is  due  to  the  circulation  of  abnormal  biliary  constituents  in  the  blood. 
In  diabetes  an  irritable  condition  of  the  skin  is  very  common,  and  in  many  cases  of  Brighfs 
disease  it  is  also  met  with.  Indeed,  the  connection  between  cutaneous  pruiitus  and  renal 
disorder  is  so  intimate  that  in  every  case  of  chronic  itching  of  the  skin  occurring  without 
apparent  cause,  a  careful  examination  of  the  urine  should  be  made.  In  this  connection  it 
may  be  mentioned  that  severe  and  prolonged  cutaneous  irritation  may  be  one  of  the  causes 
of  albuminuria.  The  ingestion  of  certain  drugs  is  well  known  to  occasion  itching  of  the 
skin,  and  the  pruritus  resulting  from  opium  is  mentioned  by  many  of  the  earliest  medical 
^^•riters.  In  advanced  age  pruritus  is  occasionally  found  to  be  a  distressing  and  intractable 
affection.  Sudden  changes  of  temperature  often  give  rise  to  it,  and  the  change  from  light  to 
heavy  underclothing  in  the  autumn  or  early  winter  is  apt  to  occasion  a  temporary  itching  of 
the  skin  in  many  persons. 

The  cause  of  localized  pruritus  is  often  found  to  reside  in  a  venous  congestion  of  the  part. 
In  pruritus  ani,  e.  g.,  the  suffering  is  invariably  aggravated  by  constipation  and  obstruction 
of  the  portal  circulation,  whUe  in  pruritus  vulvae,  uterine  engorgement  and  pregnancy  are 
well  kno^\'n  to  be  exciting  causes.  In  children,  worms  are  not  infrequently  productive  of 
itching,  not  only  of  the  anus  but  of  the  nose. 

Diagnosis.  In  cutaneous  pruritus,  as  has  already  been  stated,  there  are  no  primary 
lesions.  There  is  simply  an  itching  of  the  skin  with  the  excoriations  or  scratch-marks  wliicli 
result  from  the  use  of  the  finger  nail?  In  many  cases  the  skin  presents  a  normal  appear- 
ance at  the  time  of  examination,  and  the  diagnosis  must  be  based  upon  the  statement  of  the 
patient  as  to  the  constant  or  frequent  irritability  of  the  sldn  and  the  unconquerable  desire  to 
scratch  and  tear  it.  Usually,  however,  we  find  corroborative  evidence  of  this  statement  in 
tlie  form  of  hyperaemic  patches  which  have  been  recently  rubbed  or  scratched,  linear  excori- 
ations lapon  the  skin  or  disseminated  blood-crusts.  In  very  chronic  cases  there  may  be  a  cer- 
tain amount  of  pigmentation,  either  general  or  localized. 

The  absence  of  lesions,  save  those  which  result  from  scratching,  will  usually  enable  one 
lo  distinguish  the  affection  from  a  number  of  itching  eruptions  with  which  it  may  be  con- 

(186) 


PRURITUS. 

founded.  When  the  prnritus  is  localized  it  is  very  apt  to  give  rise  in  time  to  eczema,  the  con- 
stant scratching  causing  an  inflammatory  and  thickened  condition  of  the  skin.  In  general  pru- 
ritus the  affections  likely  to  be  mistaken  for  it  are  urticaria  and  the  animal  parasitic  diseases. 

Urticaria  is  readily  recognized  when  wheals  are  present,  but  as  these  lesions  have  fre- 
quently disappeared  when  the  patient  is  seen  by  the  physician,  and  only  the  marks  of  scratch- 
ing are  to  be  observed,  the  case  is  liable  to  be  considered  as  pruritus.  In  such  a  case  the  his- 
tory given  by  the  patient  of  sudden  outbreaks  of  red  or  white  "lumps,"  and  the  character- 
istic irritability  manifested  after  the  finger  nail  is  drawn  rapidly  over  the  sldn  must  serve  as 
the  basis  of  a  diagnosis. 

Scabies  will  often  occasion  itching  and  excoriation  of  the  skin  in  cases  where  there  are 
no  lesions  upon  the  hands,  and  hence  the  parasitic  origin  of  the  affection  may  be  overlooked. 
In  adult  males  a  few  inflammatory  nodules  or  excoriations  upon  the  genitals  will  point  with 
certainty  to  scabies,  and  in  children  the  fact  that  two  or  more  in  a  family  are  simultaneously 
affected  will  suggest  a  contagious  affection  in  place  of  pruritus. 

Phtheiriasis  occasionalb'  occurs  among  patients  whose  social  position  would  not  lead  one 
to  suspect  that  a  few  pediculi  were  harboring  in  their  clothing.  In  such  a  case  the  itching  of 
the  skin  is  often  unaccountable  until  a  most  careful  examination  reveals  the  hemorrhao-ic 
points  produced  by  the  "  bite"  of  the  pediculus,  or  brings  a  stray  insect  to  light,  and  thus 
settles  the  diagnosis. 

Treatment.  In  no  disease  of  the  skin  is  it  more  necessary  to  consider  the  general  con- 
dition of  the  patient  in  order  to  effect  a  cure  than  in  pruritus.  While  great  relief  will  often 
be  obtained  from  the  use  of  local  ajjplications,  it  is  evident  from  the  host  of  these  that  have 
been  recommended  that  they  only  afford  temporary  palliation  of  the  trouble,  and  that  o-en- 
eral  treatment  must  be  relied  upon  to  effect  a  cure.  Attention  to  the  internal  disorders  whicli 
have  been  already  mentioned  as  causing  or  aggravating  the  itching  of  the  skin  is  the  first 
step  in  treatment,  and  in  some  cases  the  only  step  which  is  necessary  to  be  taken.  When  no 
abnormal  state  of  the  stomach,  liver  or  kidneys  can  be  detected,  the  tone  of  the  patient's  sys- 
tem should  be  improved  by  hj-gienic  treatment,  and  in  many  obstinate  cases,  an  entire  chano-e 
of  diet,  scene,  etc.,  will  not  only  improve  the  patient's  health,  but  at  the  same  time  di\'ert 
his  mind  from  the  condition  of  his  skin  until  a  cure  is  unconsciously  effected. 

Of  internal  remedies  a  number  have  been  recommended  as  tending  to  allay  cutaneous 
hypersesthesia.  Of  these  gelseminum  and  pilocarpine  deserve  especial  mention.  The  value 
of  gelseminum,  as  an  anti-pruritic,  as  suggested  by  Bulkley,  I  have  found  to  be  quite  marked 
in  a  number  of  cases,  especially  in  old  people.  Prom  ten  to  fifteen  drops  of  the  fresh  tincture 
may  be  given  at  bed  time  or  at  intervals  of  two  or  three  hours,  until  the  itching  is  controlled 
or  the  chai'acteristic  toxic  effect  of  the  drug  is  noted.  Pilocarpine  may  be  given  in  the  form 
of  fluid  extract,  in  small  and  repeated  doses,  until  a  slight  decrease  of  perspiration  is  noted, 
when  the  pruritus  will  often  be  found  to  have  disappeared  or  abated.  Hypodermic  injections 
of  the  muriate  of  pilocarpine  have  produced  excellent  results  both  in  the  pruritus  of  youth 
and  old  age.     Behrend  speaks  highly  of  the  internal  use  of  carbolic  acid. 

(187) 


DISEASES  OF  TEE  SKIN— NEUROTIC. 

The  local  remedies  which  have  been  employed  for  the  relief  of  itching  are  innumerable, 
the  majority  of  them  being  of  much  less  value  than  one  would  infer  from  the  statements 
made  as  to  their  effects.  At  best  they  are  simply  palliative  and  only  relieve  the  patient's 
suffering  until  the  cause  of  the  itching  is  removed.  Warm  baths  containing  starch  or  carbo- 
nate of  soda  will  soften  a  dry,  harsh  skin  or  soothe  an  irritated  one,  and  constitute  one  of  the 
most  important  methods  of  local  treatment  in  cases  of  universal  pruritus.  After  the  bath 
the  skin  may  be  rubbed  with  alcohol  and  anointed  with  some  mildly  stimulating  unguent. 

The  stimulating  applications  which  cause  the  skin  to  tingle  or  bum  for  a  few  minutes 
are  often  followed  by  a  complete  relief  of  the  itching  for  several  hours.  Of  these  carbolic 
acid  is  one  of  the  most  reliable  if  used  of  sufficient  strength.  The  following  lotion  may  be 
used  at  first,  diluted  with  two  or  more  parts  of  water,  and  then  gradually  increased  to  its 
full  strength,  if  found  nescessary.

Chloroform  is  a  good  local  remedy  and  may  be  used  in  the  form  of  the  officinal  liniment. 

Pruritus  of  the  anus  is  often  relieved  by  the  pressure  of  a  tuft  of  cotton  or  other  foreign 
body  iatroduced  into  the  sphincter,  when  lotions  and  ointments  have  failed  to  give  relief. 
Pruritus  of  the  vulva  may  likewise  be  relieved  by  introducing  a  tampon  of  cotton  soaked  in 
glycerine  and  water,  with  a  string  attached  for  its  convenient  removal. 

DERMATALG-IA. 

Synonym — Neuralgia  of  the  Skin. 

In  certain  rare  cases  a  limited  portion  of  the  skin  becomes  the  seat  of  an  intense  pain  or 
burning  sensation  which  is  generally  paroxysmal  in  character.  This  may  exist  without  any 
change  in  the  appearance  of  the  skin,  although  in  most  cases  the  sensation  is  apt  to  be 
quicldy  followed  by  an  erythematous  condition,  and  in  some  instances  by  the  outbreak  of 
vesicles.  The  affection  is  always  symptomatic  in  character  and  is  due  to  some  lesion  of  the 
nen-e  centres  or  tract  leading  to  the  affected  part.  In  some  cases  it  has  been  referred  to  a 
nerve  lesion  of  syphilitic  origin,  and  in  other  cases  has  been  observed  in  connection  with 
locomotor  ataxia.  It  is  most  apt  to  occur  in  middle  aged  females,  and  particularly  at  the 
period  of  the  menopause.  I  have  recently  seen  a  lady  suffering  from  locomotor  ataxia  whose 
foot  and  ankle  gave  her  intense  pain,  which  was  referred  to  the  skin,  and  which  was  invaria- 
bly followed  by  an  erythema  and  indistinct  herpetic  eruption. 

Treatment.  The  application  of  hot  water  may  be  resorted  to  in  this  affection,  or  the 
oleate  of  mercury  and  morphia  rubbed  into  the  skin.

FAVUS    CAPITIS 


FAVU3    CORPORIS. 


CHAPTER  VIII. 

PARASITIC  DISEASES. 
PAVUS. 

Synonym — Tinea  Favosa. 

Favns  is  a  parasitic  disease  occurring  upon  the  scalp  or  on  non-hairy  parts,  and  is  char- 
acterized by  the  development  of  sulphur-colored  cup-shaped  crusts.  These  are  not  met  with 
at  all  stages  of  the  disease,  although  they  are  generally  present.  At  the  beginning  there 
may  be  simply  a  circular  f arfuraceous  patch,  which  on  the  body  cannot  be  distinguished 
from  trichophytosis  or  ringworm.  Soon,  however,  bright  yellow  specks  are  seen,  and  as  the 
cup-shaped  crusts  rapidly  develop,  it  will  be  noted  on  the  scalp  that  each  one  is  seated  at  the 
mouth  of  a  hair  follicle,  and  that  its  centre  is  generally  perforated  by  a  hair.  As  these 
"  cups"  become  numerous  they  tend  to  coalesce,  and  a  thick,  irregular  crust  of  lighter  color 
is  formed,  and  the  original  cup-shaped  crusts  can  be  found  only  about  hairs  at  the  margin  of 
the  large  patch. 

If,  in  any  case  of  incipient  favus,  the  crusts  be  removed  and  the  hair  shaven,  the  scalp 
will  appear  smooth  and  m  a  tolerably  healthy  condition,  and  the  development  of  the  disease 
may  be  conveniently  studied.  In  about  two  weeks  the  parasitic  growth  which  has  remained 
in  the  follicl<^s  will  show  itself  on  the  surface  of  the  scalp  in  the  form  of  minute  yellow 
crusts  around  some  of  the  growing  hairs.  These  crusts  being  covered  with  a  layer  of  epider- 
mis are  not,  strictly  speaking,  upon  the  surface.  When  in  a  few  days  they  have  reached  the 
size  of  a  split  pea,  the  margin  becomes  elevated  and  the  centre  depressed,  forming  the  favus 
"cup."  This  is  concave  on  the  upper  surface  and  convex  beneath,  fitting  into  a  correspond- 
ing depression  of  the  scalp,  which  is  covered  with  a  very  thin  layer  of  epidermis.  The 
peculiar  form  of  the  cup  arises  in  the  following  manner :  The  spores  of  the  parasite  grow 
between  the  layers  of  the  epidermis,  at  the  funnel-shaped  mouth  of  the  hair  foUicle.  As  the 
fungous  mass  increases  in  bulk,  it  raises  the  superficial  layer  at  the  periphery  of  the  disc 
above  the  surface  of  the  skin,  while  in  the  centre,  where  the  epidermis  is  in  connection  with 
the  hair,  and  immovable,  a  pit  is  consequently  formed.  On  the  under  surface  nothing  hin- 
ders the  mass  in  its  growth  from  pressing  down  upon  the  succulent  cells  of  the  rete,  and  the 
convexity  of  the  inferior  surface  of  the  cup,  and  the  corresponding  depression  of  the  scalp 
is  thus  produced.  When  a  case  of  favus  goes  untreated  the  crusts  invade  a  large  portion  of 
the  scalp,  increase  in  bulk  while  fading  in  color,  and  finally,  becoming  quite  friable,  break 
uiid  tend  to  fall  off  in  piecemeal.     The  pressure  of  the  cups  causes  atrophy  of  the  haii-  roots. 

(189) 


DISEASES  OF  THE  SKIN.— PARASITIC. 

and  bald  spots  of  a  dull,  purplish-red  hue,  and  cicatricial  appearance  are  seen  after  the  fall 
of  the  crasts.  The  hair  nevei-  grows  with  normal  luxuriance  after  a  severe  attack  of  favTis, 
but  the  scalp  is  covered  with  a  sparse  growth  of  wiry  and  curling  hairs.  The  disease,  un- 
treated, persists  until  the  whole  scalp  is  affected,  and  the  hair  very  nearly  destroyed. 

The  disease  presents  somewhat  different  features  according  to  its  seat.  On  the  head, 
where  it  usually  appears,  it  is  not  often  seen  by  the  physician  at  the  outset,  but  only  when, 
through  ignorance  or  wilful  neglect  or  mismanagement,  it  has  been  allowed  to  extend  over  con- 
siderable ground.  Favus  epidermidis,  or  f  avus  corporis,  as  it  is  more  appropriately  termed, 
is  not  as  apt  to  be  as  severe  as  favus  capitis.  It  does  not  present  the  accumulation  of  friable 
crust,  and  is  far  more  amenable  to  treatment,  on  account  of  the  inability  of  the  spores  to 
take  root  in  deep  follicles.  The  reddened  and  scaly  circular  patches  which  precede  the  devel- 
opment of  the  cups,  and  present  a  notable  similarity  to  patches  of  ringworm,  can  be  well 
studied  in  these  cases.  Sometimes  favus  co-exists  upon  the  scalp  and  non-hairy  parts,  bxit 
in  a  number  of  cases  of  favus  corporis  coming  under  my  observation,  the  scalp  has  been  free. 
It  has  been  reported  as  attacking  the  finger  nails,  and  from  the  itching  of  the  affected  scalp 
its  transference  to  the  nails  would  not  appear  strange. 

Favus  occurs  chiefly  in  childhood,  although  from  lack  of  proper  treatment,  it  may  per- 
sist upon  the  scalp  and  be  observed  in  middle  life.  It  is  i-are  in  this  country,  as  compared 
with  its  occurrence  in  some  parts  of  Europe.  The  disease  is  contagious,  and  as  it  is  trans- 
ferred directly  to  another,  those  most  Likely  to  contract  it  are  children  in  schools  and  crowded 
tenements.  Though  a  local  disease,  it  seems  to  flourish  best  upon  the  scalp  and  skin  of  those 
who  are  poorly  fed  and  cared  for,  and  those  in  impaired  health.  Family  pets  aie  often  a 
source  of  the  disease,  and  in  every  case  of  its  occurrence  in  a  household,  it  is  well  to  exam- 
ine the  dog  and  the  cat.  Mice  seem  peculiarly  subject  to  favus,  and  are  often  caught  with 
large,  yellow  crusts  upon  their  heads.  Through  the  cat  they  transmit  the  disease  to  some 
member  of  the  family.  In  spontaneous  cases,  it  is  probable  that  the  spores  have  been  carried 
through  the  air,  and  found  a  favorable  nidus  upon  a  moist  scalp  or  patch  of  skin.  A  well- 
marked  case  of  favus  of  the  scalp  exhales  a  peculiar  odor,  which  has  been  likened  to  that  of 
mice  or  of  an  ill-kept  menagerie. 

Treatmkxt.  The  treatment  is  simple,  although  it  requires  much  time  and  patience  to 
cure  a  case  in  which  the  scalp  is  extensively  affected.  Favus  of  non-hairy  parts  can  be  readily 
cured  by  softening  and  scraping  off  the  crusts  and  applying  one  of  the  numerous  parasiticide 
remedies.  A  few  weeks,  at  most,  sufiice  for  a  cure.  Upon  the  scalp  the  spores  of  the  para- 
site have  usually  invaded  the  deepest  portion  of  the  follicles,  and  consequently  no  superficial 
applications  can  effect  a  radical  cure,  at  least,  until  the  hairs  have  been  pulled  out.  This 
must  be  done  over  the  whole  of  the  affected  surface,  and  in  obstinate  cases,  repeated  a  num- 
ber of  times.  After  the  epilation,  a  one-half  per  cent,  lotion  of  corrosive  sublimate,  or  a 
three  per  cent,  ointment  of  chrysophanic  acid  may  be  well  rubbed  into  the  scalp  several  times 
a  day,  and  continued  until  both  scalp  and  hairs  have  apparently  assumed  a  tendency  to 
healthy  growth.     Even  now,  however,  it  cannot  be  asserted  that  the  disease  is  cured,  with-

out  a  microscopical  examination  of  some  of  the  new  hairs  from  different  portions  of  the 
scalp. 

TRICHOPHYTOSIS. 

Synonyms — Herpes  Tonsurans. —  Tinea  Triehophytina. — Ringworm. 

Trichophytosis  is  an  affection  of  the  sldn  resulting  from  the  growth  of  a  microscopic 
plant  called  the  Trichophyton.  It  is  one  of  the  three  vegetable  parasitic  diseases  of  the  skin, 
the  other  two  being  chromophytosis  a  ad  favus.  Like  these,  trichophytosis  is  contagious, 
possessing  the  quality  in  a  far  more  marked  degree  than  chromophytosis.  Children  are  more 
susceptible  than  adults  to  contagion,  and  when  once  introduced  into  a  family  or  school  the 
disease  is  apt  to  be  conveyed  from  one  to  another  untU  nearly  all  are  affected.  It  is  some 
times  obsen^ed  in  horses,  cows,  cats  and  other  domestic  animals. 

From  the  peculiarities  presented  by  trichophytosis,  according  to  its  location,  iive  regional 
forms  of  the  disease  may  be  conveniently  described.  These  are  given  below  in  the  order  of 
their  importance,  and  with  their  most  frequent  synonyms  appended.

On  the  general  surface  of  the  body  (T  corporis),  where  the  eruption  can  be  most  satisfac- 
torily observed,  the  disease  begins  either  in  the  form  of  a  group  of  minute  vesicles,  or  a  small, 
reddened,  scaly  macule,  which,  increasing  in  size,  presents  a  circular  outline  and  a  slightly 
elevated  margin.  The  skin  is  but  slightly  inflamed  as  a  rule,  and  at  the  advancing  border  of 
a  typical  patch  a  circle  of  minute  vesicles  may  be  sometimes  discovered  upon  close  examina- 
tion. The  patch  extends  at  the  periphery,  and  as  the  elevated  margin  creeps  over  the  healthy 
skin,  the  central  portion  becomes  but  slightly,  if  at  all  elevated,  and  far  less  scaly  than  the 
border.  In  many  cases  the  enclosed  area  becomes  quite  normal  or  remains  somewhat  pig- 
mented, and  the  eruption  presents  a  characteristic  annular  appearance.  There  is  rarely  but 
a  single  focus  of  disease,  and  in  many  instances  a  score  or  more  of  circular  patches  may  be 
counted.  When  these  are  near  each  other  they  coalesce  as  they  increase  in  size,  and  large 
patches  of  irregular  outline  result. 

Trichophytosis  of  non-hairy  parts  (T.  corporis)  occurs  in  both  sexes,  and  at  almost  all 
ages.     It  has  been  reported  as  occurring  upon  an  infant  six  hours  old. 

In  the  genito-crural  region  (T.  cruris)  the  parasite  grows  luxuriantly,  owing  to  the  heat 
and  frequent  moisture  of  the  parts  affected,  and  the  eruption  extends  upon  the  buttocks  and 
inner  surface  of  the  thighs.  It  produces  in  this  region  an  unusual  amount  of  dermatitis,  and 
in  many  subjects  a  pronounced  eczema.  In  the  tropics  this  form  of  disease  is  common  and 
obstinate.

DISEASES  OF  TEE  SKIN:— PARASITIC. 

On  the  scalp  (T.  capitis)  or  bearded  portion  of  the  face  (T.  barbae)  the  disease  begins  in 
the  form  of  one  or  several  small,  scaly  patches.  After  having  existed  a  short  time  without 
treatment,  the  hairs  springing  from  the  patch  lose  their  lustre,  become  brittle,  and  finally 
break  off  very  near  the  surface  of  the  skin.  The  patch,  which  has  now  perhaps  reached  the 
size  of  a  cent  or  quarter  dollar,  appears  bald  at  first  glance,  but  on  close  inspection  is  found 
to  be  covered  with  white  powdery  scales,  through  which  the  broken  hairs  project  like  stubble. 
Trychophytosis  capitis  is  never  seen  in  adults,  although  the  occurrence  of  the  disease  upon, 
the  bearded  portion  of  the  face  is  by  no  means  uncommon.  Trichophytosis  of  the  beard 
may  be  contracted  in  the  barber's  chair,  and  constitute  one  form  of  the  so-called  "  barber's 
itch,"  which  term  is  usually  made  to  include  eczema  and  sycosis.  It  does  not  arise  from  the 
use  of  an  unclean  razor,  as  is  commonly  imagined,  but  from  the  use  of  a  damp,  soiled  towel, 
which  furnishes  a  most  excellent  nidus  for  the  growth  of  any  vegetable  parasite. 

In  certain  cases  of  ringworm  of  the  scalp  or  beard  a  marked  inflammatory  reaction  is 
occasioned  by  the  penetration  of  the  spores  into  the  deeper  portion  of  the  hair  follicles.  A 
peculiar  condition  of  the  skin  is  produced,  which  differs  greatly  in  appearance  from  the  ordi- 
narj'  form  of  the  disease.  It  is  commonly  knoAvn  as  kerion,  or  the  kerionic  form  of  ringwonn. 
It  usually  begins  with  the  developinent  of  one  or  several  small,  pea-sized  tumors,  which  are 
always  reddened  and  "boggy,"  and  which  often  present  a  deceptive  feeling  of  fluctuation 
which  is  apt  to  lead  one  to  declare  them  abscesses.  In  spite  of  the  appearance  presented  bj^ 
these  little  tumors,  it  is  a  noteworty  fact  that  they  rarely  if  ever  suppurate.  The  fluid  con- 
tained in  the  deeper  portion  of  the  corium,  and  which  gives  to  the  swollen  part  its  soft, 
spongy  feeling,  is  a  highly  albuminous  serum,  which  appears  in  the  form  of  viscid,  honey- 
like drops,  at  the  dilated  orifices  of  the  follicles,  especially  after  the  hairs  have  loosened  and 
fallen.  This  loss  of  hair,  which  usually  takes  place  soon  after  the  affection  has  developed, 
is  limited  to  the  portion  of  the  scalp  affected.  The  little  tumor  remains  for  an  indefinite 
period  of  a  livid  red  hue,  and  then  tends  to  gradually  fade  and  flatten,  unless  similar  lesion* 
develop  in  the  immediate  vicinity.  Sometimes,  especially  in  young  children,  it  enlarges 
peripherally,  and  forms  a  soft,  flattened,  and  but  slightly  elevated  disk,  as  large  as  a  half 
dollar.  Generally,  a  group  of  closely  packed  tumors,  or  mounds,  develop,  and  the  symp- 
toms already  described  as  pertaining  to  a  single  small  tumor  present  themselves  in  an  exag- 
gerated form. 

Trichophytosis  affecting  the  nails  (T.  vvguium)  is  extremely  rare,  but  it  maj'  occur 
either  alone  or  in  connection  with  rings  of  the  disease  tipon  the  hands  or  other  portions  of 
the  body.  The  nails,  one  or  more  of  which  may  be  affected,  become  thickened,  discolored, 
and  friable.     Those  of  the  fingers  are  more  likely  to  suffer  than  those  of  the  toes. 

Diagnosis.  The  diagnosis  of  trichophytosis  is  often  so  simple  that  it  can  be  made  by 
the  patient.  When  the  eruption,  however,  has  been  treated  and  partially  cured,  or  when,  on 
the  other  hand,  it  has  been  maltreated  or  overtreated,  so  that  it  has  become  obscured  by  a 
secondary  eczema,  the  physician  must  be  cautious  in  venturing  an  opinion  until  a  microscopic 
examination  has  determined  the  presence  or  absence  of   the  parasite.     The  diseases  with 

(192) 


TRIG  HO  PR  TTOSIS. 

A-.  liicli  it  is  most  likely  to  be  confounded  are  favus,  psoriasis  and  eczema.  In  tlie  early  stage 
of  favus,  before  the  characteristic  yellow  crusts  have  developed,  the  appearance  presented  is 
very  similar  to  ringworm,  and  a  diagnosis  can  only  be  based  on  a  microscopic  examination  of 
the  hairs.  Psoriasis  sometimes  appears  in  the  form  of  circular,  reddened  patches,  mth  a 
very  moderate  amount  of  scaling,  closely  resembling  the  patches  of  trichophytosis,  and 
wlien  on  the  wane  they  tend  moreover  to  heal  in  the  center,  and  form  rings  which  have  often 
been  mistaken  for  ringworm  by  physician  as  well  as  patient.  The  peculiar  location  and  sym- 
metry of  the  eruption  in  psoriasis  will  generally  serve  as  a  guide  in  diagnosis. 

Eczema  may  simulate  every  skin  disease.  In  its  dry  and  scaly  stage,  especially  when 
occurring  as  one  or  more  small  roundish  patches,  such  as  may  be  met  with  on  the  face,  breast 
or  hands,  it  resembles  trichophytosis  in  being  hyperaemic,  scaly  and  itchy  in  a  moderate 
degree.  The  patch  of  eczema,  however,  is  rarely  circular,  and  generally  shades  off  into  the 
surrounding  skin  instead  of  presenting  an  abrupt  margin.  Furthermore,  there  is  never  any 
tendency  toward  healing  in  the  central  portion  of  the  patch.  Trichophytosis  capitis  is  often 
confounded  with  eczema,  bi^tthe  circular  form  of  the  patch,  the  absence  of  moisture,  and  par- 
ticularly the  mealy  epidermis  and  the  short,  broken  hairs  ought  to  reveal  the  nature  of  the 
affection  in  most  cases.  In  all  doubtful  cases  of  skin  disease,  where  trichophytosis  or  one  of 
the  other  parasitic  diseases  is  suspected,  microscopical  examination  of  a  few  scales  or  hairs 
must  be  resorted  to  in  order  to  settle  the  question.  The  diagnosis  of  a  weU-marked  case  of 
kerion  is  attended  vsdth  no  difficulty.  The  bald  and  lumpy  condition  of  the  scalp  is  not  seen 
in  any  other  affection.  In  the  earlier  stage  of  kerion  a  mistake  might  readily  occur.  Where 
there  are  a  number  of  scattered  red  and  soft  tubercles  upon  the  scalp  they  might  be  mistaken 
for  boils,  abscesses  or  for  syphilis.  The  latter  disease  would  not  be  likely  to  occur  at  the  age 
when  the  kerion  is  commonly  met  with,  unless  it  were  hereditary,  in  which  case  it  would  not 
manifest  itself  in  the  fonn  of  tubercles  limited  to  the  scalp.  Boils  would  be  recognized  by 
their  more  conical  form,  indurated  base,  and  tendency  to  suppuration,  while  a  number  of 
small  equal-sized  abscesses  would  not  be  apt  to  occur  upon  the  scalp  without  apparent 
cause.  After  tlie  hair  has  faUen  from  the  little  tumors,  and  the  boggy  feeling  lessened,  they 
might  be  regarded  as  indications  of  incipient  alopecia  areata ;  but  in  this  affection  the  bald 
patches  show  no  signs  whatever  of  past  or  present  inflammation,  the  affected  scalp  being ' 
white,  smooth,  and  not  at  all  elevated.  "Where  a  portion  of  scalp  is  suddenly  attacked,  and  a 
copious  discharge  of  gummy  serum  takes  place,  the  affection  bears  a  resemblance  to  an  acute 
eczema.  It  will  be  noted,  however,  that  the  hairs  are  loosened  and  pull  easily,  which  is  never 
the  case  in  eczema  of  the  scalp. 

Treatment.  As  trichophytosis  is  essentially  a  dermatitis  of  greater  or  less  severity, 
resulting  from  the  growth  of  a  parasitic  fungus  in  or  tipon  the  skin,  its  treatment  must  con- 
sist mainly  in  the  use  of  local  measures.  As  the  trichophyton  will  take  root  and  thrive  upon 
a  perfectly  healthy  skin,  it  is  evident  that  internal  treatment  cannot  effect  a  cure.  At  the 
same  time  clinical  observation  teaches  that  in  certain  conditions  of  the  system  the  skin  affords 
a  more  favorable  soil  for  the  development  of  the  fungus.     The  affection  appears  to  be  more 

(193) 


DISEASES  OF  THE  SKm.— PARASITIC. 

disposed  to  spread,  and  to  be  less  easily  checked  by  the  action  of  parasiticides,  when  the 
patient  is  ill-nourished  or  physically  depraved.  Internal  roni^dies  may,  therefore,  in  a  slight 
deo-ree  at  least,  prove  conducive  to  a  cure,  and  in  a  majority  of  cases  it  is  advisable  to  look 
well  after  the  general  health  while  carrying  out  the  local  treatment.  Cod-liver  oil,  by  pro- 
moting nutrition  of  the  skin,  and  bathing,  by  rousing  into  activity  the  cutaneous  functions, 
produce  a  beneficial  effect,  and  are  especially  called  for  by  the  class  of  patients  affected,  many 
of  whom  are  of  a  lymphatic  temperament,  averse  to  fatty  food,  and  with  a  dull,  torpid,  pasty 
skin. 

The  main  object  of  local  treatment  should  be,  (1)  to  reduce  any  undue  amount  of  inflam- 
mation, shoidd  such  be  present,  and  (2),  to  destroy  the  very  last  germ  of  the  parasite.  Suc- 
cess depends  upon  the  appropriateness  of  the  remedy.  Failure  may  result  from  the  use  of 
one  which  is  too  weak,  or  from  the  too  long  continued  use  of  one  which  is  unnecessarily 
strono-.  In  most  cases  vigorous  local  treatment  may  be  instituted  at  once,  but  on  the  soft  skin 
of  childhood,  and  on  certain  regions  in  the  adult  where  the  skin  is  thin  and  easily  inflamed, 
it  is  preferable  to  employ  the  milder  parasiticide  remedies  for  a  greater  length  of  time,  than 
to  risk  the  production  of  a  severe  dermatitis  or  eczema.  To  destroy  the  parasite  it  is  usually 
necessary  to  destroy  the  epidermis  and  hairs  which  are  invaded.  Where  the  disease  occurs 
on  non -hairy  parts,  it  is  commonly  superficial  and  easUy  cured.  As  the  spores  and  mycelium 
grow  between  the  cells  of  the  horny  layer  of  the  epidermis  it  is  evident  that  whatever  will 
remove  this  layer  wUl  carry  away  with  it  the  j)arasitic  growth.  When  this,  however,  has 
grown  down  into  the  hair  follicles,  and  even  penetrated  the  hairs  themselves,  the  disease  is 
not  readily  cured.  It  maj'  indeed  prove  exceedingly  intractable,  and  recur  after  it  is  appa- 
rently well. 

The  treatment  of  kerion  consists  in  improving  the  general  tone  of  the  patient,  and  in 
thoroughly  epilating  the  affected  part.  Whether  the  disease  is  of  parasitic  origin  or  not, 
epilation  is  demanded  by  the  condition  of  the  hairs,  which  are  not  broken  off,  but  lie,  as  in 
case  of  sycosis,  lilie  foreign  bodies  in  the  inflamed  follicles.  Their  extraction  removes  a 
source  of  irritation,  and  the  free  discharge  of  viscid  serum  through  the  follicles  lessens  the 
boggy  condition  of  the  scalp  and  promotes  the  subsidence  of  inflammation.  It  must  not  be 
exjiected  that  epilation  will  effect  a  speedy  cure  of  the  affection,  even  when  the  trichophytic 
fungus  is  present  as  an  exciting  cause.  As  the  fungus,  in  this  case,  is  not  the  sole  cause  of 
the  peculiar  phlegmonous  condition,  its  removal  with  the  hairs  will  not  produce  as  striking 
an  improvement  as  in  cases  of  ordinary  trichophytosis  capitis. 

On  the  general  surface  of  the  body,  where  the  hairs  are  fine  or  absent,  the  disease  can  be 
removed  mechanically  by  scrubbing  the  affected  part  daily  with  sapo  viridis.  This  alone  will 
usually  suffice,  but  the  patient  is  apt  to  be  more  contented,  and  indeed,  the  cure  may  be 
hastened,  if  he  applies  an  ointment  or  a  lotion  to  the  affected  part  between  the  soap  frictions. 
An  ointment  of  thymol  (three  to  five  per  cent.),  or  of  carbolic  acid  (ten  to  fifteen  per  cent.\ 
or  a  lotion  of  the  hyposulphite  of  sodium  (twenty  per  cent.),  will  be  found  very  useful. 
These  remedies  have  the  power  to  arrest  the  development  of  vegetable  spores,  if  not  to

atterlj-  destoy  them,  but  to  secui-e  their  beneficial  action  they  must  be  applied  with  great 
frequency,  as  the  parasitic  spores  multiply  with  amazing  rapidity,  and  no  time  should  be  lost 
between  the  applications.  Most  of  the  so-called  parasiticides,  however,  merely  have  an 
astringent  or  slight  caustic  action,  and  would  be  more  properly  termed  epiderrnicides.  Com- 
mon ink,  and  a  copper  cent  dipped  in  vinegar,  are  valued  remedies  among  the  laity,  and  not 
wholly  without  effect ;  but  the  physician  will  do  better  to  paint  the  patches  with  acetic  acid 
or  the  tincture  of  iodine.  The  latter  is  objectionable  when  the  affection  is  on  the  face  or 
hands,  o\ving  to  the  staining  of  the  skin.  If  decolorized,  the  tincture  loses  much  of  its  effi- 
cacy. A  still  better  application  is  a  five  per  cent,  ointment  of  chrysophanic  acid,  or  one  of 
the  remedies  already  spoken  of  as  acting  in  a  truly  parasiticidal  manner.  Blistering  a  patch 
with  cantharidal  collodion,  or  some  other  epispastic,  is  a  most  efficacious  plan  of  removing 
the  disease,  but  is  rarely  called  for. 

In  the  genito-crural  form  of  the  disease  the  parasitic  growth  is  rather  difficult  to  get  rid 
of,  as  strong  applications  must  be  used  with  caution.  But  the  chief  difficulty  in  treating 
this  form  arises  from  the  fact  that  it  is  so  frequently  associated  with  an  erythematous  eczema. 
The  skin  is  reddened,  thickened  and  itchy,  and  even  when  the  parasite  has  been  destroyed 
by  the  use  of  pure  sulphurous  acid,  or  the  remedies  already  suggested,  the  outline  of  the 
patches  and  their  general  appearance  remain  pretty  much  the  same.  In  other  words,  the 
eczema  still  remains  to  be  treated. 

The  treatment  of  trichophytosis  capitis  is  similar  to  the  treatment  of  favus,  after  the 
crusts  have  been  removed,  and  consists  mainly  in  epilation.  In  trichophytosis  the  hairs  are 
more  difficult  to  extract  than  in  favus,  since,  owing  to  the  penetration  of  spores  into  the 
fibrous  portion  of  the  shaft,  the  hairs  break,  and  a  patch  has  to  be  epilated  repeatedly  before 
the  scalp  is  left  smooth  and  clean.  The  prognosis  of  this  affection  is  much  better  than  in 
favus  of  equal  extent,  since  the  hair  bulbs  are  not  so  apt  to  be  destroyed,  and  consequently 
the  bald,  depressed  spots  and  the  sparse,  wiry  hair,  which  usually  result  from  a  severe  attack 
of  favus,  do  not  follow.  After  trichophytosis  of  the  greater  portion  of  the  scalp,  the  hair 
may  in  time  grow  as  thick  and  strong  as  ever. 

Epilation  may  be  performed  in  various  ways.  I  have  made  some  use  of  an  epilating 
paste,  composed  of  resin,  wax  and  balsam  of  tolu,  molded  into  the  form  of  a  convenient 
stick,  about  an  inch  in  diameter.  One  end  of  this  being  melted  by  heat  and  pressed  upon 
the  patch,  a  sudden  twist  and  jerk  will  extract  a  large  number  of  hairs  at  once  ;  but  the 
epilating  forceps  are  almost  universally  used  for  this  purpose.  They  should  be  carefully 
made,  with  broad,  accurately-closing  and  slightly-roughened  blades.  If  too  stiff  they  are 
certain  to  tire  the  fingers  of  the  operator  where  a  patch  of  any  size  is  to  be  epilated.  When 
the  scalp  or  beard  is  recently  affected,  the  patches  small,  and  the. hairs  normal,  epilation  is 
not  necessary.  The  patches  may  be  shaved,  and  parasiticide  applications  vigorously  applied 
for  a  considerable  length  of  time.  If,  now,  the  microscope  shows  no  indications  of  a  parasitic 
disease  after  repeated  examination  of  thehaii-sand  epidermic  scales,  the  shaving  may  be  discon- 
tinued, but  the  patches  must  be  closely  watched  for  a  mouth  or  two,  lest  the  disease  reappear.

DISEASES  OF  TEE  SKIN:— PARASITIC. 


CHROMOPHYTOSIS. 

Synonyms — Pityriasis   Versicolor. —  Tinea  Versicolor. —  Chloasma, — Hver  8pot$. 

Ckromopliytosis  is  another  of  the  three  important  affections  of  the  skin  which  owe 
their  origin  to  the  growth  of  a  vegetable  parasite  or  fungus.  It  is  contagious,  though  not  in 
a  marked  degree,  and  patients  seldom  have  any  idea  of  the  manner  in  which  they  contracted 
the  affection.  The  trunk  and  upper  extremities  are  its  favorite  and  almost  its  sole  seat.  It 
sometimes  extends  upon  the  neck,  and  even  upon  the  cheeks,  and  may  be  found,  in  rare 
instances,  upon  the  thighs.  It  usually  commences  upon  the  upper  portion  of  the  breast,  and 
in  many  cases  is  quite  symmetrical  in  its  development.  Although,  at  the  beginning,  the 
eruption  may  be  one-sided  in  respect  to  situation,  in  nearly  all  cases  of  long  standing,  where 
the  whole  trunk  is  more  or  less  affected,  the  symmetrical  disti-ibution  of  the  eruption  is  a 
marked  feature. 

The  affection  begins  in  the  form  of  a  few  pin-head-sized,  yellowish,  scaly  spots,  which  grad- 
ually increase  in  size  and  number.  When  first  noticed  by  the  patient,  there  may  be  a  score  or 
more  of  isolated,  brownish-yellow,  pea-sized  circular  patches,  showing  very  distinctly  upon 
the  background  of  the  normal  skin,  or  there  may  be  a  small  irregular  patch  of  the  same 
color,  variable  in  size,  with  a  few  isolated  circular  spots  scattered  near  its  margin.  As  the 
eruption  increases  in  extent,  it  spreads  over  the  upper  portion  of  the  chest  and  follows  down 
the  median  line  as  a  rule  towards  the  pubis.  The  back  likewise  becomes  affected,  though  not 
generally  in  so  marked  a  degree  as  the  breast.  The  sternal  region,  though  often  the  first  to 
present  the  eruption,  frequently  becomes  free  in  an  advanced  stage.  The  groins  are  usually 
exempt,  and  the  axillae  and  sides  of  the  chest  are  not  as  thickly  covered  as  the  breast  and 
back. 

The  circular  discs  are  usually  slightly  elevated,  but  the  diffused  patches  are  less  so,  and 
sometimes  can  with  difficulty  be  distinguished  from  normal  skin.  The  margin  may  be  quite 
abrupt,  or  it  may  shade  off  so  imperceptibly  that  it  is  difficult  to  say  exactly  where  the 
affected  skin  begins. 

Itching  is  present  in  a  moderate  degree  in  some  cases,  but  generally  there  is  nothing  to 
attract  the  patient's  attention  to  the  trouble,  and  in  patients  who  bathe  Little,  the  affection 
may  exist  for  a  long  time,  and  then  be  accidentally  discovered.  Though  occurring  often 
among  those  who  pay  due  attention  to  personal  cleanliness,  and  hence  met  with  in  private 
practice,  it  is  far  more  common  in  that  class  of  i^ersons  who  perspire  freely  and  bathe  sel- 
dom. In  dispensary  practice  patients  rarely  apply  for  treatment,  unless  a  guilty  conscience 
leads  them  to  mistake  the  eruption  for  a  manifestation  of  syphilis  ;  and  yet,  where  patients 
with  syphilis  and  other  affections  are  stripped  for  examination,  chromophytosis  in  greater  or 
less  extent  is  very  frequently  observed. 

The  disease  may  exist  for  the  greater  portion  of  a  lifetime  if  nothing  be  done  to  remove 
it.     In  some  cases  a  small  patch  or  number  of  patches  show  no  tendency  whatever  to  spread,

CHROMOPHYTOSIS. 

v>  liile  in  other  cases  portions  of  the  body  become  quickly  covered,  and  the  eruption  shows  a 
marked  tendency  to  retnm  after  treatment.  The  disease  is  only  met  with  in  adults,  and 
occurs  with  nearly  equal  frequency  in  either  sex.  It  is  common  in  early  adult  life,  and 
rarely  if  ever  seen  upon  the  aged. 

Diagnosis.  The  affection  is  generally  recognized  with  ease  by  the  color,  the  peculiar 
configuration  of  the  patches,  and  the  scaling  of  the  epidermis  when  scratched  lightly  -nith 
the  finger  naU.  In  cases  where  the  patient  has  bathed  and  nsed  soap  freely,  the  disease  may 
be  extensive,  and  yet  be  only  recognized  by  the  yellowish  or  tawny  hue  which  it  imparts  to 
the  skin.     In  case  of  doubt,  the  microscope  will  settle  the  question  at  once. 

Treatment.  As  the  disease  is  a  strictly  local  one,  local  measures  will  effect  a  cure. 
Care  must  be  taken,  however,  that  the  treatment  is  faithfully  carried  out  by  the  patient,  else 
the  disease  Avill  only  be  apparently  cured,  and  in  a  short  time  will  reappear.  Two  points 
should  always  be  borne  in  mind.  Firstly,  that  the  affection  is  confined  to  the  epidermis,  and 
whatever  means  wiU  remove  the  outer  layers  of  epidermic  cells  will  necessarily  remove  the 
disease.  Secondly,  that  it  Is  useless  -to  cure  nine-tenths  of  the  disease,  for  if  a  single  spot  be 
left,  or  even  if  the  same  underclothing  be  worn  again,  without  being  thoroughly  cleaned,  tlie 
eruption  is  almost  certain  to  return. 

Soap  will  cure  a  great  many  cases,  if  the  skin  be  scrubbed,  rather  than  rubbed  with  it, 
or  if  it  be  rubbed  into  the  affected  patches  daily,  and  allowed  to  remain  for  a  week.  A  bath 
taken  then  will  remove  considerable  dead  epidermis,  and  with  it  the  spores  and  mycelium  of 
the  parasite.  Common  soft  soap  may  be  used  when  the  sapo  viridis,  or  green  soap,  is  not 
easily  obtained.  The  following  ointment  or  paste  I  have  used  in  many  cases,  and  always  with 
the  most  satisfactory  results.

The  tincture  of  iodine,  painted  over  the  patches,  and  daubed  on  the  small  circular  spots, 
wiU  cause  the  epidermis  to  peel  off,  and  thus  remove  the  disease.  This  remedy,  even  diluted, 
changes  the  color  of  the  affected  patches  to  a  much  darker  brown  than  the  noi-mal  skin,  and 
hence  is  of  advantage  in  revealing  the  presence  of  minute  spots  which  might  readily  be  over- 
looked. An  ointment  of  chrysophanic  acid  quickly  cures  the  affection,  but  is  objectionable 
on  account  of  its  tendency  to  inflame  the  skin,  and  to  stain  the  clothing.  When  the  patient 
is  apparently  free  from  the  eruption,  it  is  well  to  apply  for  several  weeks  a  lotion  of  carbolic 
Jfccid  of  five  per  cent,  strength,  or  the  following  more  agreeable  preparation :

DISEASES  OF  THE  SKIN.—PAEASITIC. 


SCABIES. 

Synonym —  The  ItcK 

Scabies  Is  an  affection  of  the  skin,  resulting  primarily  from  the  burrowing  of  minute 
insects  called  "acari."  The  presence  of  these  parasites  in  the  skin  occasions  a  severe  pruri- 
tus, and  provokes  a  characteristic  eruption,  which  cannot  be  duly  appreciated  and  rationally 
treated  without  a  certain  knowledge  of  their  anatomical  striactnre  and  peculiar  habits 

The  Acarus  Scabiei,  or  itch-mite,  is  a  minute  and  almost  microscopic  insect.  It  can  be 
readily  seen  with  the  naked  eye  when  extracted  from  its  burrow  or  cuniculus  by  means  of  a 
needle,  but  its  features  can  only  be  studied  beneath  the  microscope.  The  mature  acarus  is  of 
oval  shape,  and  provided  with  eight  legs.  The  male  is  smaller  than  the  female,  does  not 
burrow  as  does  the  latter,  and  is  not  readily  found.  The  young  acari  jDossess  but  six  legs 
(two  posteriorly),  and  these  are  in  time  thrown  off  with  its  skin,  when  the  mature  eight-leg 
ged  insect  appears.  If  a  female,  she  becomes  speedily  impregnated  by  the  male,  who  roams 
at  night  upon  the  free  surface  of  the  skin.  She  then  proceeds  to  burrow,  and  deposit  her 
ova  to  the  number  of  a  dozen  or  more  beneath  the  epidermis.  At  the  end  of  this  burrow  she 
dies,  unless  prematurely  removed  by  the  finger  nail  of  her  imwilling  host.  The  ova  are 
hatched  within  fourteen  days,  and  find  their  way  to  the  surface  of  the  skin.  Here  the 
maiden  acari  are  wooed,  become  impi'egnated,  and  the  burrowing  and  hatching  process  is 
repeated.  The  burrows  are  generally  found  where  the  skin  is  thin  and  warm,  as  between  the 
fingers,  upon  the  penis  in  the  male,  and  the  nipple  in  the  female.  They  appear  as  dotted, 
slightly  elevated  and  curving  lines.  Vesicles  and  pustules  are  frequently  observed  in  their 
vicinity,  but  the  extensive  eruption  which,  in  some  severe  cases,  covers  the  bodj^  and  extremi- 
ties, is  not  a  direct  effect  of  the  burrowing  of  the  acari,  but  results  from  the  free  use  of  the 
finger-nails.  The  itching  is  almost  intolerable,  especially  in  the  night,  when  the  patient  is 
warm  in  bed. 

The  eruption  in  scabies  is  localized  in  great  measure  according  to  the  character  of  the 
patient's  clothing,  and  differs  in  this  respect  in  men,  women  and  children.  Upon  the  hands 
and  wrists  it  is  common  in  all,  but  its  prevalence  about  the  breasts  of  women,  and  upon  the 
genitals  in  men  and  boys  seems  to  depend  upon  the  ease  with  which  they  can  scratch  in  those 
localities,  especially  at  night.  In  young  children,  who  wear  long,  close-fitting  night-dresses, 
the  anldes,  which  alone  are  exposed,  are  usually  the  seat  of  an  eruption.  The  face  and  scalp 
are  usually  free  from  eruption,  even  in  the  most  severe  cases  of  scabies.  A  secondary  eczema, 
however,  may  be  found  upon  the  head,  as  well  as  on  the  body.  The  disease  is  usually  con- 
tracted at  night,  from  some  affected  bedfellow.  The  physician  may  handle  the  hands  of  a 
patient  with  impunity,  according  to  my  experience.  Nevertheless,  one  writer  has  stated 
that  he  contracted  the  disease  "  from  incautiously  handling  and  hunting  for  the  mite  on  a 
child's  arm." 

Diagnosis.    The  diagnosis  of  scabies  may  be  based  upon  the  discovery  of  burrows,  or, 

(198) 


SCABIES 


roType,  e.  bierstaot 


SCABIES. 

in  the  event  of  not  finding  them,  upon  the  characteristic  locality  of  the  excoriated  papulea 
which  constitute  the  eruption.  The  burrows  are  more  apt  to  be  found  in  mild  and  recent 
cases  than  in  severe  cases,  where  the  hands  are  covered  with  vesicles  and  pustules.  When 
the  occupation  of  the  patient  causes  the  hands  to  be  kept  very  much  in  water,  they  may  ap- 
pear perfectly  free  from  the  disease,  and  yet  a  characteristic  eruption  exist  on  the  body. 

Treatment.  The  treatment  of  scabies  depends  upon  the  age  of  the  patient,  the  chro- 
nicity  of  the  disease,  and  the  presence  of  a  secondary  eczema.  In  infants,  whose  tender  skin 
would  certainly  become  inflamed  from  use  of  the  ordinary  stimulating  sulphur  ointment, 
squal  parts  of  vaseline  and  balsam  of  Peru  may  be  employed  with  a  satisfactory  result.  In 
children  and  adults  stronger  applications  may  be  made,  although  it  must  be  remembered 
that  some  skins  can  bear  what  others  cannot.  Styrax  balsam,  in  the  form  of  a  liniment, 
made  by  adding  twenty  per  cent,  of  olive  oil,  or  as  an  ointment,  made  from  an  equal  part  of 
cosmoline,  is  an  agreeable  and  effective  application.  Sulphur,  however,  has  long  been  the 
chief  remedy  in  scabies,  and  although  others  may  be  equally  good,  there  seems  to  be  none 
more  efiicacious  in  the  majority  of  cases.  It  is  frequently  combined  \vith  carbonate  of  potas- 
sium, mercury,  tar,  chalk,  etc.,  but  as  far  as  my  experience  goes,  these  compound  ointments 
possess  no  marked  advantage  over  a  simple  sulphur  ointment,  which,  if  applied  in  strength 
suitable  to  the  case  and  to  the  various  parts  of  the  body,  vnl\  leave  nothing  to  be  desired. 
The  Ungt.  Sulphuris  (U.  S.  P.)  consisting  of  thirty  parts  of  sulphur  to  seventy  parts  of  lard, 
is  rather  stronger  thai^is  necessary,  especially  when  its  application  is  to  be  repeated,  and  com- 
bined with  baths  and  soap  frictions.  A  twenty,  or  even  a  ten  per  cent,  ointment  is  prefera- 
ble m  most  cases,  for  the  patient  generally  prefers  to  be  cured  pleasantly  and  permanently, 
to  being  cured  quicldy.     A  ten  per  cent,  ointment  of  naphthol  is  also  an  efficient  remedy. 

In  a  recent  case  of  scabies,  smearing  the  hands  at  night  with  the  ointment  may  suffice  to 
effect  a  cure  ;  but  when  the  disease  is  of  long  standing,  the  whole  body  with  the  exception  of 
the  head,  should  be  anointed.  Before  going  to  bed,  the  patient  may  remain  for  a  quarter 
of  an  hour  in  a  warm  bath.  This  macerates  the  epidermis  upon  the  hands  and  other  affected 
parts  to  such  a  degree  that  a  brisk  friction  with  soap  will  doubtless  exhume  some  of  the 
acari,  and  certainly  increase  the  effect  of  the  ointment  which  is  to  be  subsequently  applied. 
Hebra  warns  against  the  injudicious  use  of  warm  baths,  but  the  effect  of  bathing,  in  predis- 
posing of  the  skin  to  eczematous  inflammation  is  only  noticed  when  one  employs  the  very 
strong  applications  which  he  recommends.  If  the  eruption  is  seated  on  a  delicate  skin,  and 
especially  if  an  eczematous  tendency  manifests  itself,  baths  may  be  discarded,  while  the  oint- 
ment is  used  with  great  care,  and  not  continued  but  for  a  few  days  at  a  time. 

Disinfection  of  the  clothing  is  unnecessary  in  most  cases,  if  not  in  all.  It  is  important, 
however,  to  treat  not  only  the  patient  who  applies  for  treatment,  but  also  the  bed-fellows, 
playmates  or  associates  who  may  be  similarly  affected.  Otherwise  the  disease  will  be  re-con- 
tracted as  soon  as  it  is  fairly  cured. 

The  duration  of  the  treatment  must  necessarily  vary.  Ordinary  cases  can  be  cured  in 
from  live  to  ten  days.    It  is  always  difficult  to  say  just  when  the  patient  is  curtd,  and  when, 

(199)

therefore,  the  treatment  should  cease.  Too  often  the  treatment  is  continued  on  account  of 
an  eruption  which  is  not  due  to  the  acari,  but  to  the  irritating  applications  which  are  being 
employed. 

PHTHEIRIASIS. 

Synonyms — Pediculosis. — Lousiness. 

Phtheiriasis  is  a  term  which  includes  both  the  presence  of  lice  and  the  cutaneous  lesions 
to  which  their  presence  gives  rise.  In  some  cases,  where  an  eczematous  tendency  on  the 
part  of  the  patient  exists,  the  external  irritation  and  consequent  scratching  is  sufficient  to 
occasion  patches  of  typical  eczema.  The  older  writers  regarded  the  affection  in  the  light  of 
a  specific  dyscrasia,  of  which  the  pediculi  were  a  natural  result,  and  among  the  laity  at  the 
present  time  it  is  a  common  belief  that  the  lice  come  out  of  the  skin,  where  they  are  sup- 
posed to  be  bred  by  the  disease. 

Pediculi  are  insects  belonging  to  the  group  of  hemiptera.  They  are  without  wings, 
possess  a  sucldng  mouth,  and  undergo  no  metamorphosis.  There  are  three  members  of  the 
family  which  are  parasites  of  the  human  body,  viz.,  the  pediculus  capitis  or  head-louse,  the 
pediculus  corporis  or  body-louse  and  the  pediculus  pubis  or  crab-louse.  These  occasion  the 
three  affections  known  as  Phtheiriasis  capitis,  Phtheu-iasis  corporis  and  Phtheiriasis  pubis. 

The  pediculus  capitis  is  of  a  whitish  color,  and  varies  in  size  from  one  to  three  millime- 
tres in  length.  Attached  to  its  thorax  are  six  hairy,  jointed  and  clawed  legs,  with  which 
it  is  enabled  to  travel  rapidly  along  and  among  the  hairs.  It  is  only  met  with  upon  the 
scalp.  The  lice  deposit  their  ova  either  singly  or  in  groups  upon  the  hairs.  These  ova 
or  "nits"  are  found,  upon  close  examination,  to  be  whitish,  pyriform  bodies,  glued  to  the 
hairs  with  the  smaller  end  close  to  the  shaft  and  pointing  toward  the  scalp.  They  are 
always  deposited  near  the  root  of  the  hair,  and  accordingly,  when  observed  near  the  free 
extremity,  it  is  an  indication  that  the  affection  has  existed  for  a  considerable  length  of  time. 

The  pediculus  corporis  bears  a  strong  resemblance  to  the  pediculus  capitis,  although  it  is 
somewhat  larger.  Its  habits  are  quite  peculiar.  It  does  not  burrow  in  the  skin  like  the  acarus 
or  itch-mite,  nor  is  it  ever  found  in  the  hair  like  the  other  species  of  pediculi.  It  inhabits 
the  clothing  and  merely  pastures  upon  the  skin.  It  does  not  bite,  but  sucks  the  blood  of  its 
victim  through  a  haustellum  or  proboscis  which  it  inserts  into  the  skin.  Its  appetite  is  vora- 
cious, and  when  observed  beneath  a  watch-glass,  during  meal-time,  its  bodj'^  may  be  seen  to 
increase  in  size  and  assume  a  darker  or  reddish  color.  When  numerous  the  pediculi  may  be 
seen  traveling  over  the  free  surface  of  the  patient's  apparel,  but  when  a  strict  search  is  neces- 
sary to  discover  them,  they  will  generally  be  found  secreted  in  the  folds  and  seams  of  the 
garments.  In  cheap  lodging-houses,  police  stations  and  wherever  lousy  persons  are  in  the 
various  habit  of  sleeping,  the  bed-ticks  and  woolen  blankets  may  become  infested. 

'ITie  pediculus  pubis  is  a  smaller,  broad-bodied  louse,  which  may  infest  any  harry  part 
»ixcept  the  scalp.  As  the  name  implies,  it  is  commonly  met  with  in  the  pubic  region,  but 
occasionally  it  is  found  in  the  axilla,  upon  the  sternum,  in  the  beard,  and  upon  the  eyelashes.

PHTHEIRIASIS. 


PHTHEIRIASIS  CAPITIS. 


Phtheiriasis  capitis  is  an  extremely  common  affection  among  the  lower  classes.  Thougn 
most  frequently  attacking  children,  and  especially  those  who  associate  with  a  number  of 
others  in  schools,  asylums  and  similar  institutions,  it  is  not  infrequent  among  adults.  Filth 
and  neglect  act  as  predisposing  causes,  but  at  the  same  time,  children  who  have  every  possi- 
ble attention  paid  them  are  often  affected,  and  even  ladies  of  wealth  and  refinement  sometimes 
discover  that  they  have  been  unconsciously  harboring  a  large  number  of  unwelcome  and  dis- 
gusting vermin.  Men,  on  account  of  their  short  hair,  are  much  less  likely  to  be  attacked. 
It  is  a  notable  fact  that  certain  individuals  are  peculiarly  liable  to  become  affected  whenever 
exposed,  and,  in  case  of  some  children  whose  heads  are  carefully  washed  and  cared  for,  it  is 
a  puzzling  matter  to  account  for  the  repeated  presence  of  the  insects  in  the  hair. 

The  first  symptom  produced  by  the  presence  of  the  pediculi  is  an  unpleasant  itching  of 
the  scalp.  In  children,  the  continued  scratching  produces  excoriations,  and  a  serous  or  sero- 
purulent  discharge  soon  appears,  which  tends  to  mat  the  hairs.  An  eczema,  especially  upon 
the  occipital  region,  is  frequently  evoked,  and  this  is  so  characteristic  that,  when  limited  to 
this  region,  it  should  always  lead  to  a  search  for  pediculi  as  its  probable  cause.  An  eruption 
of  contagious  pustules,  as  in  the  case  illustrated,  may  appear  upon  the  neck  and  shoulders. 
In  strumous  children  the  irritation  of  the  scalp  may  lead  to  a  marked  swelling  of  the  Ij'm- 
phatic  glands  of  the  neck. 

Diagnosis.  The  diagnosis  of  the  affection  is  readily  made  if  the  pediculi  are  found,  but 
the  presence  of  nits  upon  the  hairs  is  alone  sufficient  to  establish  it,  since  they  indicate  that 
there  have  been,  and  probably  will  be,  pediculi  in  the  hair,  even  though  none  may  have  been 
discovered  by  a  careful  investigation. 

"When  eczema  of  the  scalp  exists  the  presence  of  pediculi  is  often  overlooked,  and  the 
affection  may  be  unsuccessfully  treated  until  its  parasitic  origin  is  discovered.  As  above 
stated,  occipital  eczema  is  an  almost  certain  sign  of  phtheiriasis. 

Treatment.  The  treatment  vai'ies  with  the  extent  of  the  affection  and  the  social  condi- 
tion of  the  patient.  In  dispensary  practice  it  is  usually  advisable  to  have  the  child' s  hair 
cut  close,  especially  in  warm  weather.  If  no  eczema  is  present  the  lice  and  nits  may  be  de- 
stroyed by  rubbing  the  scalp  night  and  morning  with  ordinary  kerosene.  Caution  should  be 
given  respecting  the  danger  of  setting  the  child's  head  on  fire  by  rubbing  in  the  oil  in  too 
close  proximity  to  a  gas-jet  or  candle.  When  severe  eczema  is  present  this  must  be  treated 
by  means  of  a  soothing  ointment,  although  it  is  sometimes  advisable  to  destroy  the  parasitic 
cause  of  the  eczema  at  the  outset,  even  though  the  treatment  should  aggravate  the  eczema- 
tons  condition.  In  private  practice  it  is  not  necessary  to  have  the  hair  cut,  and,  with  proper 
attention,  it  will  be  found  easy  to  cure  the  affection  by  careful  combing  and  the  nightly 
inunction  of  the  ammoniated  mercury  ointment.  The  nits  are  sometimes  difficult  to  remove, 
but  this  may  be  accomplished  by  rubbing  each  affected  hair  from  root  to  tip  with  a  sponge  or 
soft  cloth  dipped  in  alcohol  or  cologne-water.

DISEASES  OF  THE  SKIN.— PARASITIC. 


PHTHEIRIASIS  CORPORIS. 


Phtheiriasis  corporis  implies  the  presence  of  lice  in  the  clothing,  together  with  the  exist- 
tence,  to  a  greater  or  less  degree,  of  certain  cutaneous  lesions.  The  affection  is  common,  and 
often  a  chronic  one  among  the  poor  and  miserable,  and  under  certain  circumstances,  the  pos- 
sessor of  wealth  and  refinement  is  not  protected  against  an  acute  attack.  As  Professor  Hebra 
once  remarked  to  his  students,  it  is  not  always  a  disgrace  to  have  lice,  but  it  is  a  disgrace  not 
to  get  rid  of  them  speedily. 

The  lesions  constituting  the  eruption  in  phtheiriasis  corporis  are  :  (1)  peculiar  hemon-ha 
gic  specks  or  so-caUed  "bites,"  (2)  small  wheals  or  inflammatorj^  papules,  (3)  excoriations 
either  presenting  a  raw  surface,  or  covered  mth  a  crust  of  dried  blood,  (4)  scratch  marks  ol 
parallel  direction,  such  as  are  not  met  with  upon  the  skin,  except  as  a  i-esult  of  phtheiriasic 
irritation,  and  (5)  pustules,  furuncles  and  supei-ficial  ulcerations. 

The  eruption  is  observed  chiefly  upon  the  body  and  thighs.  It  is  always  most  marked 
in  certain  localities  which  correspond  to  the  seams  and  folds  of  the  clothing,  where  the  pedi- 
culi  secrete  themselves,  and  deposit,  in  great  numbers,  their  small,  white  and  shining  eggs. 
A  tract  of  skin  that  can  be'  almost  covered  by  the  palm,  lying  between  the  upper  portion  of 
the  scapulae,  is  a  spot  most  likely  to  present  excoriations,  since  it  is  a  favorite  habitat  of  the 
lice,  and  quite  accessible  to  the  hands  of  the  patient.  The  eruption  in  this  locality  usually 
presents  a  striking  appearance,  the  skin  being  frequently  pigmented,  and  showing  old  cica- 
trices scattered  among  the  recent  excoriations.  The  eruption  is  also  apt  to  be  well  marked 
around  the  loins,  presenting  a  distribution  which  might  be  termed  the  phtheiriasic  girdle. 
This  is  commonly  observed  when  the  trousers  are  supported  by  a  belt.  Excoriations  are 
common  about  the  trochanteric  region  and  outer  aspect  of  the  thighs,  when  the  trousers  are 
chiefly  infested.  I  have  seen  a  patient  with  dark  stripes  running  down  the  thighs  and  legs, 
and  corresponding  to  the  seams,  which  were  swarming  with  pediculi  and  their  ova. 

Diagnosis.  The  diagnosis  of  phtheiriasis  corporis  can  usually  be  made  by  observing 
the  patient  at  a  respectful  distance — a  very  fortunate  circumstance  for  the  physician,  who  in 
charity  practice  has  to  treat  a  large  number  of  cases.  When  the  patient  strips,  the  nature  o/ 
the  affection,  if  it  be  of  long  standing  and  weU-marked,  is  evident  from  the  characteristic  loca 
tion  of  the  scratch  marks,  and  from  the  fact  that  the  patient  finds  it  impossible  to  keep  hi? 
bands  stUl.  There  is  no  other  disease  in  which  the  pruritus  is  so  intense  as  in  a  severe  case 
of  phtheiriasis.  Exposure  of  the  body  to  the  cool  air  seems  to  excite  the  desire  to  scratch. 
If  the  patient  is  requested  to  stand  perfectly  still,  with  his  hands  hanging,  he  may  retain  his 
soldier-like  position  for  a  few  seconds,  when  he  wiU  probably  begin,  with  both  hands,  to  rub 
and  scratch,  and  even  to  tear  the  skin,  until  it  is  bleeding  at  numerous  points.  The  pruritic 
character  of  the  eruption  being  thus  manifest,  we  are  led  at  once  to  exclude  a  diagnosis  of 
syphiloderma  and  every  other  non-pruritic  skin  affection,  and  to  think  of  urticaria,  prurigo, 
eczema,  or  scabies,  eruptions  which  are  always  accompanied  by  severe  itching.  The  irrita- 
bility of  the  skin,  shown  by  the  parallel  pink  streaks  which  follow  in  the  wake  of  the  finger-

nails,  and  tjie  rapidly  developing  white  ridges  or  small  wheals,  is  a  striking  feature  of  urti 
caria,  and  might  lead  to  the  diagnosis  of  this  affection.  But  in  urticaria  the  severe  excoria 
tions  are  lacking,  and  the  eruption  is  usually  of  recent  and  sudden  development.  Prurigo 
in  the  severe  form,  which  is  seen  in  the  skin  clinic  of  Vienna,  is  rarely,  if  e^er,  met  with  in 
this  country.  In  a  mild  form  it  is  occasionally  encountered,  and  can  be  distinguished  from 
phtheiriasis  by  its  attacking  chiefly  the  extremities,  and  being  invariably  a  disease  of  long 
standing. 

A  case  of  phtheiriasis  might  be  diagnosed  as  one  of  papular  or  pustular  eczema,  the  dif- 
ference in  the  appearance  of  these  eruptions  not  always  being  very  marked  ;  but  the  charac- 
teristic location  of  excoriations  across  the  back  of  the  shoulders,  around  the  waist,  and  upon 
the  outer  surface  of  the  hips  and  thighs,  should  point  at  once  to  their  parasitic  origin.  Sca- 
bies, when  affecting  the  body  extensively,  may  resemble  phtheiriasis,  but  it  manifests  a 
strong  preference  for  the  hands,  forearms,  lower  part  of  abdomen,  genitals,  and  the  inner 
aspect  of  the  thighs,  while  avoiding  the  favorite  seats  of  phtheiriasic  lesions.  It  is  intensely 
pruritic,  as  the  common  name  of  "the  itch"  suggests,  but  the  patient  scratches  with  com- 
parative gentleness,  and  never  digs  the  skrn  with  fury,  as  in  case  of  phtheiriasis. 

It  will  thus  be  seen  that  the  diagnosis  is  easy,  in  a  severe  form  of  the  affection,  but  fre- 
quently cases  occur  in  which  only  a  moderate  pruritus,  with  very  few  excoriations,  is  present. 
Here  it  may  be  impossible  to  discover  any  pediculi,  and  it  is  sometimes  extremely  difficult  to 
distinguish  the  affection  from  the  pruritus  cutaneus,  which  is  a  neurotic  affection,  depend- 
ing upon  some  internal  disorder.  The  hemorrhagic  points  produced  by  the  haustellum  of 
the  pediculus  can  generally  be  discovered,  however,  and  serve  an  excellent  purpose  in  point- 
ing out  the  parasitic  origin  of  the  trouble.  When  in  private  practice  there  exists  a  suspicion 
of  pediculi  (and  phtheiriasis  is  not  wholly  confined  to  dispensary  patients),  it  is  far  prefera- 
ble to  quietly  hunt  for  these  characteristic  lesions  of  the  disease,  than  to  give  offense  to  a 
patient  by  instituting  a  fruitless  search  through  the  clothing. 

Treatment.  The  treatment  of  phtheiriasis  corporis  consists  in  getting  rid  of  the  pedi- 
culi, and  soothing  the  irritation  of  the  skin,  which  their  attacks  have  occasioned.  In  dispen- 
sary practice,  I  might  say  that  the  first  aim  of  treatment  should  be  to  convince  the  patient 
that  the  eruption  is  not  due  to  "  heat "  or  "humor"  in  the  blood,  but  that  it  is  the  natural 
result  of  lice  in  his  clothing.  The  patient  may  be  ignoi-ant  of  the  existence  of  lice,  (though 
generally  is  conscious  of  their  presence),  but  yet  so  thoroughly  possessed  with  the  idea 
that  they  are  the  effect,  rather  than  the  cause,  of  the  eruption,  that  it  is  vain  to  argue  the 
point,  and  hopeless  to  give  directions  for  treatment.  Such  cases  can  only  be  treated  satisfac- 
torily in  hospitals,  where  enforced  cleanliness  is  possible.  When  the  patient  appreciates  the 
fact  that  the  lice  cause  the  eruption,  he  may  be  directed  to  change  his  clothing  throughout, 
with  a  fair  prospect  of  his  doing  so.  It  is  not  sufficient,  as  many  patients  imagine,  to  put  on 
a  clean  shirt  once  or  twice  a  week,  or  even  oftener.  The  patient  must  be  told  and  shown,  if 
necessary,  that  the  outer  garments  are  infested,  and  that  it  is  essential  to  change  these  as  well 
as  the  underclothes.     AVhile  the  latter  are  being  boiled,  the  former  may  be  baked  in  a  hot

DISEASES  OF  THE  SKm.— PARASITIC. 

o:  en,  with  the  probable  result  of  destrojdng  both  lice  and  ova.  It  may  not  be  superfluous, 
he  wever,  after  the  clothes  have  been  thoroughly  baked,  to  sprinkle  the  seams,  where  the  ova 
were  numerous,  with  sulphur,  pyrethrum  or  staphisagria.  As  regards  the  eruption  on  the 
body,  this  will  quickly  disappear  when  its  cause  is  removed.  A  daily  warm  bath  ^vill  prove 
agreeable  and  beneficial  when  the  skin  is  greatly  irritated.  For  dispensary  patients  I  usually 
prescribe  an  ointment  or  lotion  of  carbolic  acid,  which  tends  to  allay  the  itching,  and  to 
repel  the  parasite. 

PHTHEIRIASIS  PUBIS. 

Phtheiriasis ^m5i«  is  a  pruriginous  affection  of  the  hairy  region  to  which  "crab-lice" 
have  gained  access.  The  mons  pubis  is  the  part  usually  affected,  as  the  lice  are  apt  to  be 
transferred  from  one  individual  to  another  during  sexual  intercourse.  Their  presence  occa- 
sions a  considerable  amount  of  itching  and  the  frequent  scratching  of  the  affected  part  soon 
gives  rise  to  an  eruption  of  small  papules,  and  in  some  cases  to  an  eczematous  condition. 
The  lice  are  not  readily  discovered,  if  unsuspected,  but  a  careful  examination  usually  reveals 
a  number  of  minute  bodies  adhering  closely  to  the  roots  of  the  hair.  When  these  are  dis- 
lodged and  placed  upon  a  white  paper  and  viewed  with  a  keen  eye  or  magnifying  glass,  they 
will  be  readily  recognized  as  pediculi. 

TREATiiE>'T.  The  blue  mercurial  ointment,  which  is  a  favorite  lay  remedy  for  this  affec- 
tion, is  certainly  efficacious,  although  objectionable.  When  freely  applied  it  evokes  an 
eczema  of  the  affected  part.  A  sparing  use  of  the  ammoniated  mercury  ointment  is  far  pref- 
erable.
